Purpose Antibiotic resistance (ABR) has now become a major global public health issue. New legislation has recently been introduced in Northern Ireland from April 2017, requiring domestic households to recycle all domestic food waste items. Resulting increases in the volume of such waste which is collected by the local council has driven technologies for the safe recycling of such material including commercial composting. Little is known about the antimicrobial resistance (AMR) profile of such composted food waste materials and hence the purpose of this paper is to characterise total AMR in bacteria isolated from such composted domestic food waste and to consider the potential public health consequences of such material. Design/methodology/approach Finished compost containing food waste material was obtained in the Spring 2017 from a local authority recycling amenity site, which freely distributes such material to the public. Total culturable populations of bacteria were isolated from the composted material and antibiotic susceptibility to six classes of antibiotics, namely florfenicol, fluoroquinolone, aminoglycoside, lincosamide, tetracycline and β-lactam was examined. Findings ABR was greatest for lincomycin > tobramycin > minocycline/amoxycillin > ciprofloxacin > florfenicol. In this study, there was one compost, which showed complete resistance to all antibiotics tested. No compost displayed complete antibiotic sensitivity. Two composts were considered pan-resistant, whilst four were considered multi-resistant. Originality/value This study showed that the total ABR profile of food waste compost is significant, with bacterial populations within the compost having ABR to several classes of antibiotics, which are important and sometimes critical to human health. The application of such materials to enrich and fertilise garden soils in significant volumes inadvertently allows for the artifical and man-made transfer of AMR bacteria and their genes to new environments, which have been hitherto niave to the presence of such AMR properties. The application of such compost horticulturally to enrich soils used to cultivate flowers, fruits and vegetables may have important consequences for human and animal health. Urgent work is now needed to quantify the fate of such antibiotic resistant bacteria from compost to their new environment and risk assessments made to estimate the carriage through to human health.

Full textAbstract:
Food management is an inefficient activity, and households are the major contributors responsible for food waste across the food supply chain. Ten years remain to halve household food waste, as recommended by the 2030 Agenda for Sustainable Development. Up to now, Italian investigations into household food waste have been research activities with limitations in measurement and sampling. The need to establish a monitoring system led the Italian Observatory on Food Surplus, Recovery and Waste to apply a methodology that permits comparison with other European countries. In 2018, a survey involving a representative sample of 1142 Italian households was carried out. The majority of respondents (77%) reported that they had wasted 370 g of food during the last week, evidence in line with data from the Netherlands and progressively different from what was found in Germany, Hungary, and Spain. Perishable products, such as fresh fruit and vegetables, bread, and nonalcoholic drinks, were mainly wasted. The most frequently disposed foods were unused (43.2%) or partly used (30.3%). As for possible causes, household food waste was significantly associated with preventive practices and ability. This study endeavored to segment household food waste based on possible drivers and barriers to preventive action, setting the stage for future monitoring, supporting policy action, and educational intervention.

Full textAbstract:
Food waste is the origin of major social and environmental issues. In industrial societies, domestic households are the biggest contributors to this problem. But why do people waste food although they buy and value it? Answering this question is mandatory to design effective interventions against food waste. So far, however, many interventions have not been based on theoretical knowledge. Integrating food waste literature and ambivalence research, we propose that domestic food waste can be understood via the concept of ambivalence—the simultaneous presence of positive and negative associations towards the same attitude object. In support of this notion, we demonstrated in three pre-registered experiments that people experienced ambivalence towards non-perishable food products with expired best before dates. The experience of ambivalence was in turn associated with an increased willingness to waste food. However, two informational interventions aiming to prevent people from experiencing ambivalence did not work as intended (Experiment 3). We hope that the outlined conceptualization inspires theory-driven research on why and when people dispose of food and on how to design effective interventions.

Full textAbstract:
In the world in general and in Ukraine in particular, there is a catastrophic environmental situation with food waste. The solution to the problem of waste accumulation, the organization of quality control of compliance with legislation in their treatment, the formation of environmental awareness of the population is hampered by the lack of unanimity in defining the essence of waste, industrial waste, waste in the regulatory framework and among scientists. The aim of the work is to study the essence of the definition of food waste in domestic and foreign scientific discussions and regulations in terms of improving the regulation of their treatment in Ukraine. Scientific discussion of domestic and foreign authors on the concept of waste, in particular food, as well as their regulations demonstrate a wide variety of not only definitions but also approaches. This takes into account the legal basis for waste operations, their physical condition and properties, environmental and economic characteristics, the criterion of goal setting, accounting approach and so on. The analysis of the existing classifications of waste stated the absence of a separate category of food waste both in the works of Ukrainian scientists and in domestic regulations, while foreign authors are actively researching this category. According to the results of the study, it is proposed to introduce into the domestic regulatory framework the term "loss of food and food waste" commonly used abroad with the following definition: products (substances) as edible parts of plants and animals produced or collected for human consumption but ultimately not consumed. Critical analysis of domestic environmental legislation in comparison with European allowed to propose the implementation of the Waste Framework Directive, as well as the formation of a hierarchy of waste management priorities: prevention, preparation for reuse, recycling, other types of disposal, elimination as Ukraine's European integration. Areas of further research will be the study of food waste disposal technologies of the modern city.

Full textAbstract:
The objective of this study was to assess the current situation of generation and management of plastic waste in Thoi Lai district, Can Tho city, Vietnam through collecting domestic solid waste samples from 30 households and interviewing 150 households using questionaires. The results showed that the average amount of domestic solid waste was 0.3 kg/person/day, in which the plastic waste accounted for 11.7% with generation rate of 0.035 kg/person/day. Shopping bags were dominant accounting for 34.7%, single-use plastic products accounting for 18.5% and food packaging plastic bags accounting for 9.51%. The generation rates of domestic solid waste and plastic waste had positive correlation with household’s size and income. In addition, the rate of plastic waste generation also appeared to have a relationship with the characteristics of the study area. Plastic waste has not been classified but it is mixed with other domestic solid waste. Knowledge of plastic waste impact has not been widely propagated in the community. Therefore, appropriate measures should be implemented to reduce municipal waste and plastic wastes.

Full textAbstract:
As it is the case in many industrialized countries, household food waste accounts for a large share of total food waste in Germany. Within this study, the characteristics of edible and inedible domestic food waste, the reasons for discarding food and the potential influence of socio-demographic factors on food waste generation are assessed. A data set of 6853 households who participated in a diary study in 2016 and 2017 was analyzed by use of descriptive statistics, parametric tests, and linear regression. The results indicate that perishable products such as vegetables, fruits, and bread are mainly affected by disposal. Moreover, household food waste occurs due to quantity problems at purchase for small households and quantity problems at home for larger households and households with children. Despite statistically significant differences in food waste amounts between household lifecycle stages, age of the head of household, household size, and size category of the municipality, socio-demographic factors have a limited power in predicting a household’s food waste level. The study has important implications for food waste policy and research regarding the issues of food waste prevention measures, quantification methodologies, and monitoring implementation.

Song, He. "Anaerobic digestion of source-segregated domestic food waste." Thesis, University of Southampton, 2016. https://eprints.soton.ac.uk/402998/.
Full textAbstract:
Anaerobic digestion (AD) is an attractive waste treatment process in which both pollution control and energy recovery can be achieved. Source-segregated domestic food waste (FW) has a high organic content on a dry weight basis and is rich in lipids and proteins, indicating the potential for a good biogas yield with high methane content. Process instability, however, has often been reported in food waste digesters, which was mainly manifested by the accumulation of volatile fatty acids (VFA) and reduction of specific methane production. Trace element (TE) supplementation has been proved to be an effective way to rectify this problem and has been applied to industrial AD plants. This practice, however, was usually characterised by a trial-and-error approach due to the lack of a clear understanding of the impact of TEs on AD under different process conditions. The aim of this study was therefore to optimise TE dosing strategies for FW digestion at different loading rates, with particular attention to the role of cobalt (Co) and selenium (Se). The limiting concentrations of Co and Se were studied in long-term continuously stirred tank reactor (CSTR)-type digester experiments at organic loading rates (OLR) from 1.8 to 5 kg volatile solids (VS) m-3 d-1. In a digester operated at OLR 1.8 kg VS m-3 d-1 without TE addition, dosing of Co at a strength of 1 mg Co kg-1 fresh matter was effective to stimulate the complete degradation of accumulated VFA. Around 2500 mg L-1 VFA built up, however, after OLR increased to 2.5 kg VS m-3 d-1; then dropped slightly by addition of Se at a strength of 0.05 mg Se kg-1 fresh matter. After stepwise increases in Se concentration to 0.2 mg kg-1, VFA reduced to less than 1000 mg L-1. In another 2 digesters, at OLR 3 and 4 kg VS m-3 d-1 respectively, TE washing-out was introduced for determination of the limiting Co concentration. All TE supplementation was ceased in these 2 digesters for around 300 days with the exception of continuous addition of 0.2 mg kg-1 of Se. VFA accumulation up to 30000 mg L-1 occurred in one digester immediately after the OLR increased from 4 to 5 kg VS m-3 d-1 and later up to 22500 mg L-1 in the other digester when OLR increased from 3 to 4 kg VS m-3 d-1. By gradually increasing Co concentration in both digesters to 0.3~0.5 mg kg-1, VFA started to be consumed. At the end of test, the recovered digester with OLR 5 kg VS m-3 d-1 was running stably with 0.2 mg kg-1 Se and 0.3~0.5 mg kg-1 Co addition, with a pH of 7.8, IA/PA ratio 0.4, specific methane production (SMP) 0.47 standard temperature and pressure (STP) m3 CH4 kg-1 VS d-1, volumetric methane production (VMP) 2.37 STP m3 CH4 m-3 d-1, and VFA concentration less than 500 mg L-1. To further understand the effect of trace elements on VFA production, short-term trials were carried out to assess their function in VFA production. The results indicated that with accumulated VFA, supplementation of trace elements stimulated VFA production to a greater extent than VFA consumption. Effect of organic loading rate on TE dosing strategy and digester performance was studied in 5 digesters, all of which had stable operation but different trace element addition histories. One pair digesters was run as control at OLR 5 kg VS m-3 d-1 over the course of the experiment, another pair operated with a gradual loading increase to 6, 7, 8 and 9 kg VS m-3 d-1. A SMP of 0.46±0.02 STP m3 CH4 kg-1 VS d-1 at OLR 8 kg VS m-3 d-1 was achieved. Volatile solids destruction (VSD) rates were similar between OLR 5 and 8 kg VS m-3 d-1, at approximately 0.74~0.75, but reduced to 0.71~0.72 at OLR 9 kg VS m-3 d-1. Residual methane production (RBP) test results showed that biogas production of digestate from OLR 5 and 7 kg VS m-3 d-1 were similar, whereas digestate from OLR 9 kg VS m-3 d-1 generated more biogas than OLR 5 kg VS m-3 d-1, indicating lower conversion efficiency was achieved at OLR 9 kg VS m-3 d-1. Nitrogen mass balance equations were developed to distinguish nitrogen distribution in digesters. These showed that microbial biomass density increased along with OLR increase, which in turn requires an increase in TE addition. The specific rate of biomass increase at OLR 9 kg VS m-3 d-1, however, was lower than at 8 kg VS m-3 d-1, reflecting the decrease in specific methane production and VSD rate. The results indicate that FW digester was able to operate at OLR 8 kg VS m-3 d-1, without loss of performance when compared with OLR 5 kg VS m-3 d-1. Loading 9 kg VS m-3 d-1 was regarded as overloaded due to the lower hydrolysis and acidification efficiency. The fifth digester, in which the same TE dosing was applied, was operated with random loading: a daily load between 2.5~7.5 kg VS m-3 d-1 was randomly introduced while weekly average OLR was maintained at 5 kg VS m-3 d-1. Stable performance was observed in this digester with 2.27 STP m3 CH4 m-3 d-1 of 30-day rolling average VMP and 76% of VSD rate, and VFA concentrations less than 500 mg L-1. Further research on essential TE supplementation for stable FW digestion at high loading was carried out. All TE additions were ceased except 0.3 mg kg-1 of Co and 0.2 mg kg-1 of Se, in two pairs of digesters at loading 5 and 8 kg VS m-3 d-1, respectively. VFA accumulation occurred in digesters at the higher loading, which finally failed. VFA fluctuated around 4000 mg L-1 in digesters at OLR 5 kg VS m-3 d-1, until the rest of trace elements in a full 11 trace elements recipe were reintroduced, when VFA degraded quickly to below 1000 mg L-1. The research provided new insight on optimising essential TE supplementation to FW digestion, especially at moderate and high loading rates, to ensure stable and high productive biogas production.

Full textAbstract:
The aim of this thesis is to explore design directions to minimize a food wastage problem in western domestic kitchens. Central to the thesis is an understanding of people&rsquos behavior towards the food waste phenomenon. Three interconnected studies and one design project are included. In Study I, 18 participants were interviewed to explore their perceptions and attitudes towards food waste, revealing the most wasted food types and reasons for food wastage. The findings of Study I are clustered under four phases of food handling: acquisition, preparation, consumption and storage. Study II comprised a generative session with three users and two designers, devised to explore latent and tacit knowledge regarding food wastage. Study II resulted in user-generated ideas for minimizing food waste, which were analyzed so as to reveal possible design directions. From these results, a set of criteria for a &lsquo
perfect&rsquo
kitchen appliance, which could minimize food waste, was drawn-up. The design project took the research findings of Study I and II and devised a collection of design concepts as possible ways to help reduce domestic food waste. Two concepts &ndash
Philips Dispense and Canvas - are taken further because they relate to the most wasted food types: &lsquo
bread&rsquo
and &lsquo
vegetables and fruits&rsquo
. In Study III, Philips Dispense and Canvas were evaluated with a questionnaire. According to the results, in households containing busy couples without children, Philips Dispense is valued highest (it takes the food waste responsibility away from users) whereas Philips Canvas was valued lower (it gives feedback on current stocks and persuades homeowners not to waste food).

Serna-Maza, Alba. "Nitrogen control in source segregated domestic food waste anaerobic digestion using stripping technologies." Thesis, University of Southampton, 2014. https://eprints.soton.ac.uk/372768/.
Full textAbstract:
Anaerobic digestion of source segregated domestic food waste (SS-DFW) offers a sustainable management route for reclaiming potential energy in the form of a fuel gas, and nutrients which can be recycled back to land. However, the biochemical characteristics of SS-DFW can lead to free ammonia nitrogen (FAN) concentrations that are inhibitory to the digestion process causing unstable operation and in some cases complete process failure, particularly in thermophilic systems. With the purpose of reducing the total ammoniacal nitrogen (TAN) in the digester, side-stream and in situ biogas stripping technologies were tested. Mesophilic and thermophilic temperatures were evaluated under moderate and complete biogas mixing rates (0.4 l min-1 – 2.6 l min-1) in a batch system. Laboratory investigations showed that TAN reductions in an in situ bubbling reactor with moderate and complete gas mixing rates were non-existent at mesophilic temperatures and minimal at thermophilic temperatures. For this reason, it is unlikely that in situ biogas stripping would be adequate to prevent TAN concentrations greater than 2500 mg N l-1 in a food waste digester and thus will not mitigate ammonia inhibition in a thermophilic system. Semi-continuous trials carried out on SS-DFW in laboratory-scale digesters, fed daily at an organic loading rate (OLR) of 2 kg VS m-3 day-1 and coupled to stripping columns at low bleed rates (2 – 3.5 % digester volume per day treated in the stripping process) were effective in reducing ammonia concentrations to below thermophilic toxic levels (TAN concentration of 2500 – 3500 mg N l-1). The experiments also confirmed that removal of a proportion of the digester contents and their exposure to thermophilic conditions with pH adjustment to 10 had no adverse effects on performance in terms of biogas production (0.83 ± 0.03 l g-1 VS without stripping, 0.84 ± 0.05 l g-1 VS with stripping) or VS destruction (81.8 % without stripping, 88.5 % with stripping). The process required high pH and temperature (≥70 ⁰C) to achieve a TAN concentration below the toxic threshold for thermophilic digestion, and it is unlikely that stripping at 55 ⁰C and pH 10 would achieve the target reduction. The research showed the way forward for the application of side-stream stripping to prevent the build-up of ammonia under thermophilic conditions, if the digester is started up with a non-inhibitory FAN concentration in the inoculum.

Full textAbstract:
To significantly reduce the volumes of food currently wasted in industrialized countries,
tackling food waste on the household level is paramount. While awareness
campaigns and economic incentives are important measures, it is crucial to look beyond
individual decision making and scrutinize how contextual factors frame consumer
lifestyles in ways that intensify the issue of food going to waste. This paper
addresses the role of material contexts-in particular, infrastructures and Technologies-
in the shaping of food shopping and storing practices and thus consumer food
waste. It presents an in-depth, qualitative study with 24 Austrian households, conducted
from November 2016 to February 2017. Data were collected through food
waste diaries, semi-structured interviews and a total of 16 focus group discussions.
In line with other studies, we find that food waste is a largely unintended outcome of
entangled daily routines revolving around food, such as meal planning, grocery shopping
and food storing. The characteristics of food retail infrastructures-in terms of
accessibility, density and type-shape these routines and thus potentially influence
excess food purchases. Food storing practices as well depend on the characteristics
of domestic infrastructures and co-evolve with technologies used for storing food.
Unraveling the interconnectivity between material contexts and household food
practices can inform policy, product design and food retail development and thus has
implications for reducing consumer food waste.

Full textAbstract:
The research focuses on developing and evaluating the performance of low cost, low technology food residue based fuel briquettes as an alternative to the widespread use of wood fuels (charcoal and firewood) for domestic cooking applications. In view of the declining accessibility of wood fuels, inadequate electrification coverage and ever-rising prices of cooking gas and kerosene in Uganda, harnessing energy from within reach, alternative sustainable energy sources such as food residues has been regarded as a viable solution to domestic cooking energy. In this research, both desktop reviews of earlier studies and laboratory investigations of the developed food residue based fuel briquettes have been considered. Carbonized sweet potato, banana (matooke) and cassava peelings were mixed in different proportions with either sweet potato or banana stem pulp (1 or 2kgs) and later densified using a hand operated molder to develop the food residue based briquettes. The drop test method was used to determine the resilience of the produced briquettes to disintegrating forces in particular during transportation and storage. An oxygen bomb calorimeter was used to determined the Higher Heating Value (HHV) of the briquettes and it ranged from 13.6 – 26 MJ/kg with cassava peelings char: sweet potato peelings char: sweet potato stem pulp 1kg giving the lowest HHV and cassava peelings char: sweet potato peelings char: banana stem pulp 2kg giving the highest HHV. Generally the tests results revealed that the type of natural binder used had an effect on both the HHV and mechanical strength of the produced briquettes.Thesis was presented and defended via Skype

Full textAbstract:
Vietnam’s fast economic growth has to a large extent been achieved on the expense of a rapid deterioration of the natural environment, including eutrophication of local water sources. Proper planning is needed to move towards a sustainable wastewater management and one recognized tool for such planning is material flow analysis (MFA). This thesis uses MFA to define the current flows of phosphorus (P) and organic matter, measured as COD, in domestic wastewater and food waste in Sông Công town, Thai Nguyen province, Vietnam. The aim is further to compare two different improved wastewater management scenarios with a business-as-usual scenario. The methods used to find data for the MFA are literature review, interviews and a survey questionnaire. The literature review presents challenges facing the wastewater sector of Vietnam and treatment techniques for wastewater and septage. The wastewater sector is affected by technical difficulties such as lack of capacity and organizational challenges as a result of adjacent and overlapping authorities. Contradictions and gaps in legislation, poor governance, and problems with financing are all issues that need to be addressed. Although the number of wastewater treatment plants in Vietnam is increasing, not more than 10 % of the wastewater is being treated. Various techniques are tried out in Vietnam, among others constructed treatment wetlands and activated sludge techniques, such as Sequencing Batch Reactors and Anaerobic/Anoxic/Oxic processes. These and other techniques are explained and compared in the literature review. From the gathered data three future scenarios for Sông Công’s wastewater and food waste treatment were created along with one of the current situation. The future business-as-usual scenario (BAU-2030) shows the development in Sông Công if no changes are implemented before year 2030, while the centralized scenario (CTP-2030) redirects flows of wastewater to a conventional chemical/biological treatment plant. The third scenario, semi-centralized (STP-2030), implements one treatment plant with enhanced biological phosphate removal (EBPR) followed by a constructed treatment wetland, and a bigger EBPR plant followed by disinfection. Both of the improved scenarios also use food waste and sludge to produce biogas and digestate that can be used as compost in agriculture. The results of the MFA indicate that if nothing is done to change the current management, a 24 % increase of pollutants to the Công River is imminent in just 15 years. On the other hand, if one of the improved scenarios is implemented, 92 % (CTP- 2030) or 90 % (STP-2030) of the P will be available for reuse in agriculture, reducing the need for artificial fertilizer. Further biogas is produced, which can substitute petroleum based gas for domestic purposes or be used to generate electricity.Vietnam har åstadkommit en snabb ekonomisk utveckling under de senaste åren, till stor del på bekostnad av den naturliga miljön. Städer och industrier har vuxit fram utan hänsyn till rening av avloppsvatten. Ett tecken på detta är övergödning av lokala vattendrag. Denna kandidatuppsats använder MFA, ett erkänt verktyg för planering av VA-system, för att kartlägga och visualisera dagens flöden av fosfor (P) och organiskt material (COD) i avlopp och matavfall i Sông Công town i Thai Nguyen provinsen, Vietnam. Syftet är även att jämföra två förbättrade scenarier med ett så kallat business-as-usual scenario. För att hitta data till MFA-beräkningarna utfördes en litteraturstudie, intervjuer och en enkätundersökning. Litteraturstudien behandlar utmaningar i Vietnams VA-sektor och reningstekniker för avlopp och anaerob behandling. VA-sektorn i Vietnam står inför en rad utmaningar för att nå långsiktig hållbarhet, däribland kapacitetsbrist och organisatoriska problem som beror på närliggande och överlappande ansvarsområden. Motsägelsefull och ofullständig lagstiftning, dåligt upprätthållna lagar och finansiering är andra problem som måste åtgärdas. Även om antalet reningsverk i Vietnam ökar så renas endast 10 % av avloppsvattnet idag. Olika reningstekniker provas runt om i landet, däribland våtmarker och aktivslambehandlingstekniker, som Sequencing Batch Reactors och Anaerobic/Anoxic/Oxic processer. Dessa och ett flertal andra tekniker förklaras och jämförs i litteraturstudiekapitlet. Baserat på de data som samlades in skapades tre framtida scenarier och ett scenario för nuläget. Business-as-usual scenariot (BAU-2030) visar hur flödena kommer se ut år 2030 om ingenting förändras från dagens läge. I det centraliserade scenariot (CTP-2030) inrättas ett centraliserat reningsverk med traditionell kemisk/biologisk rening och samtliga avloppsflöden omdirigeras dit. Det decentraliserade scenariot (STP-2030) använder två reningsverk. Ett med förbättrad fosforavskiljning (EBPR) som efterföljs av en våtmark och ett reningsverk med EBPR där desinfektion används som slutbehandling istället för våtmark. Båda de förbättrade framtidsscenarierna använder matavfall och avloppsslam för att producera biogas. Resultaten visar att om inga åtgärder genomförs kommer COD- och fosforflödena till floden Công öka med 24 % under de närmaste 15 åren. Om något av de förbättrade scenarierna införs kan 92 % (CTP-2030) eller 90 % (STP-2030) återföras till jordbruk och därmed antas ersätta konstgödsel. Eftersom de förbättrade scenarierna även innefattar biogasproduktion kan petroleumbaserad gasol ersättas i hushållen eller användas för att generera elektricitet.

Full textAbstract:
This research aimed to understand how the domestic kitchen design can help the user to reduce their food waste. From this, we had the objective to define strategies and principles directed to professionals who develop domestic kitchen designs. To accomplish this goal, we approached the themes of sustainable development and design for sustainability as the basis for proposing solutions, focusing on the user phase, that create ruptures in the current system and instigate more responsible behaviours in terms of economy, environment and society. In this sense, we investigated the problem of food waste, mainly in the Portuguese scenario, to understand its dimension, what is actually wasted and what are the factors related to this behaviour. So we presented strategies and design projects to induce behavioural change, focusing both on sustainability and food waste. From that, we systematized those that can be transported to the kitchen scenario. About the kitchen space, we presented brief chronological evolution and the design rules and parameters existing in the literature, in order to define key moments in the design process for implementation of the selected strategies. Finally, we established a set of nine strategies and their principles, which were evaluated by a sample of professionals in the sector, through online survey. From all the data and information gathered in the research, we concluded this dissertation with the design of a kitchen model, in which we implemented the established guidelines, which meant a practical evaluation of our result.Esta investigação buscou compreender como o desenho das cozinhas domésticas pode auxiliar o usuário a diminuir seu desperdício de alimentos. A partir disso tivemos o objetivo de definir estratégias e princípios direcionados a profissionais que desenvolvem desenhos de cozinhas domésticas. Para cumprir este objetivo, abordamos os temas do desenvolvimento sustentável e do design para a sustentabilidade como a base para a proposição de soluções, com foco na fase do usuário, que criem ruturas no sistema atual e que instiguem comportamentos mais responsáveis em termos de economia, meio ambiente e sociedade. Neste sentido, investigamos o problema do desperdício de alimentos, principalmente no cenário português, a fim de compreender qual a sua dimensão, o que é de fato desperdiçado e quais são os fatores relacionados a este comportamento. Apresentamos, então, estratégias e projetos de design para induzir mudança de comportamento, com foco, tanto na sustentabilidade, quanto no desperdício de alimentos. A partir disso, sistematizamos aquelas que podem ser transportadas ao cenário da cozinha. Sobre o espaço da cozinha, apresentamos breve evolução cronológica e as regras e parâmetros de projeto existentes na literatura, a fim de definir momentos chave no processo de desenho para implementação das estratégias selecionadas. Por fim, estabelecemos um conjunto de nove estratégias e seus princípios, que foram avaliadas por uma amostra de profissionais do setor, por meio de inquérito online. A partir de todos os dados e informações colhidas na investigação, concluímos esta dissertação com a criação de uma proposta de projeto modelo de cozinha, no qual implementamos as guidelines estabelecidas, o que significou uma avaliação prática do nosso resultado.

In Taiwan, the organic waste, called household food waste, is about 20 to 30 percent of trash from the average families. If not settled well, it must damage the evronment and exhaust the social cost, so its recycling is important and obligatory.There are two stage in this study. At first stage, the weights of composting and wasts pig-raising in Taipei city and county were investigated for 7 days, which is produced by 20 houses with cooking at home everyday. The statistic results were shown that the average weight of composting wasts was 2740g in Taipei city and 2620g in Taipei county, respectivery, and pig-raising wastes was 920g in Taipei city and 1075g in Taipei, respectively. As for Taipei city, the weight of its composting was lower than 5.5kg and pig-raising was lower than 2kg, so 7.5kg classified bucket was designed. At the second stage, the AIO life-style list was used to investigate the behavior of recycling of 86 subjects to improve design of bucket of household food waste. The result is that subjects were grouped into two groups, one is a glatton of work-prefered group about 76 people（84﹪）, and another is egeguntly fashiona group about 14 people（16﹪）. The former is significantly different from the latter in the preference of the bucket, including the meterials, the airtight, and the convenient of hanging, and cleaning. Finally, according to the those results, a newly imprased bucket was designed to fulfill the range and principle drawed by the analysis on evaluation of 20 peple of the urbn, and to resolve the inconvience when use recycling bucket daily.

Full textAbstract:
Globally, food waste has become a central issue in the management of municipal solid wastes. The collection and disposal of food waste (FW)is exposing environmental resources (land, water, air) to pollution levels pressure of unprecedented scale. In Australia alone, FW costs the economy close to AU$20 billion annually, and in each household, between $2,200 and $3,800 worth of food is being discarded per year. In the domestic food supply chain, understanding households’ attitudes and their behaviours towards domestic food waste (DFW) is crucial to implement realistic prevention and/or reduction policy options. Identifying communities’ preferred options is also crucial to create meaningful schemes that can motivate people to participate and adopt desirable behavioural changes. Despite these, householders’ non-market values relating to DFW are not adequately investigated and their policy implications are poorly understood.
There are currently insufficient empirical data on DFW drivers from interdisciplinary standpoints. New research is therefore required to further the understanding of the conjunction of socioeconomic, environmental, and psychological, and policy preferences that householders have in regards to DFW. Such research would provide clear evidence on which to base policy settings and best-practices; in the absence of this, food waste will continue to be a growing global concern in relation to both economic and environmental sustainability.
This research set out to address the identified gaps through a mixed methods approach, applying a case-study design in a regional Australian context. It was aimed at exploring householders’ preferences, willingness to pay for, and motivation to participate in DFW reduction options. The research was focused mainly on point-of-purchase and post-purchase stages of household food-related activities. These stages are essential components of a food supply chain that considerably influence householders’ decisions in food consumption and wastage. The research was conducted in the Rockhampton Regional Council and Livingstone Shire Council local government areas in Central Queensland, Australia. The underlying rationale for this case location is that regional areas face extra pressures on DFW reduction mainly due to the lack of economies of scale and limited access to recycling schemes compared with better-serviced metropolitan areas.
In a preliminary exploration, two focus group discussions were conducted with 17 residents, to gain understanding of DFW drivers and preferences relating to prevention and reduction scenarios. Subsequently, an online survey was conducted with 587 residents. The quantitative research data were drawn from three main sub-categories of survey questions—Likert-type behaviours, sociodemographics, and questions relating to non-market valuation of DFW attributes. Factor analyses, multiple regressions, logistic regressions, choice modelling and contingent valuation techniques were used to analyse a range of relationships between response and explanatory variables. The mixed approach to data gathering and analyses was instrumental to reveal complex conceptual constructs in DFW issues that would have been difficult to reveal if only a qualitative or quantitative approach was used.
Results from the qualitative analyses revealed a range of trade-offs that influenced the preferences for, and participation in, DFW prevention and diversion options. Overall, the participants appeared to prefer diversion through backyard composting over prevention (e.g. via education to avoid overconsumption and over-purchasing). In the quantitative analyses, a range of significant behavioural and socio-demographic predictor variables were identified. The level of support and value attached to the suggested DFW diversion option significantly varied across the residents surveyed. This indicates that it would be costly for Councils to simultaneously implement several options in an attempt to cater to the householders’ variable preferences. In that regard, the case study suggests that DFW diversion must be considered as one viable option. This would mean implementing avoidance as a non-optional measure, prompting the need to practice behavioural changes.
Overall, this research offers novel contributions to the DFW literature in terms of its interdisciplinary approach and key findings that inform conceptual advances and practical applications for future studies. The focus of the study on a regional context highlights the relevance of acknowledging regional community preferences, perspectives, and challenges relating to DFW. The research also provides policy-makers with exploratory and explanatory insights into understanding behaviours that can underpin and/or inform practical policy interventions, especially those that will be valuable at local government levels in Australia and elsewhere.

Among the various agro-industries, food processing industries are the second prime generator of wastes after domestic sewage. In the current epoch of the rapid budding world, the wastes are mounting, which robustly sway the health of ecosystems and eventually the human population. For that reason, each agro-industrial sector has critical stipulation toward the secure utilization of agro-materials all the way through recycling of wastes. A crude disposal and littering of these waste materials frequently signifies a problem that is additionally provoked by different legal restrictions. Inadequate management of these solid waste constituents could lead to drastic change in physico-chemical properties of soils. The waste product, which is discarded into the environment, is loaded with valuable compounds. They are new, innate, and monetary sources of colorants, protein, dietary fiber, flavoring, antimicrobials, and antioxidants, which can be utilized in the food industry as a basis of natural food additives.

Full textAbstract:
Traditional agricultural production is circular. Virtually no waste is produced. Residues are returned to soil as compost; used as bedding material in livestock husbandry (and returned to soil as compost) or as feed to produce animal protein and manure; utilized as construction materials; or fuel for domestic energy. Circular agricultural production ensures soil conservation, waste reduction, residues reuse, and recycling. The ever rising global population, and demand for food and agro-industrial products, necessitated a transition to linear agricultural production which generates enormous quantities of agricultural residues, agro-industrial, and food wastes. The economic losses, environmental degradation, and health hazards resulting from poor management of excess wastes, and their mitigation have been the subject of research and policy efforts at continental and regional levels. Current waste management models redirect attention to circular agricultural production and bioeconomic approaches aimed at waste reduction, reuse, and recycling. Such approaches view agricultural wastes as raw materials with economic benefits for the farmer, consumer, and investor in varied industrial enterprises (crop and animal production, animal and human health, food, beverage, neutraceutical, pharmaceutical, cosmetics, and material industries). The present review attempts to collate information on global production, and possible valorization of recyclable agro-industrial residues and food wastes.

Constructed Wetlands (CWs) are low-cost and sustainable systems for wastewater treatment. Traditionally they have been used for urban and domestic wastewater treatment, but in the last two decades, the applications for industrial wastewater treatment increased due to the evolution of the technology and the extended research on the field. Nowadays, CWs have been applied to the treatment of different kind of wastewaters as such as refinery and petrochemical industry effluents, food industry effluents including abattoir, dairy, meat, fruit and vegetables processing industries, distillery and winery effluents, pulp and paper, textile, tannery, aquaculture, steel and mixed industrial effluents. In this chapter, the authors present the main types of CWs, explain how they work and the expected performances, and describe the principal applications of CWs for industrial wastewater treatment with particular attention to suspended solids, organic matter and nutrient removal. A review of these applications as well as some case studies will be discussed.

Full textAbstract:
Abundant amount of agro wastes is produced day by day globally to manage the escalating needs of billons of human population. The agro wastes are produced from various sources mainly crops left out, agro industries, aquaculture, and livestock. The major ingredient of agro wastes are of cellulose, lignin, hemicelluloses, etc. Conventionally, most of the crops left out were used for composting, animal fodder, domestic fuel, etc. Due to modernization technology in agriculture sector, people from Third World countries prefer cost-effective methods such as combustion process. Improper management of agro waste generated in the process has been contributing toward escalating air, soil, and water pollution. A proper environmental-friendly management of agro waste is the need of the time for sustainability, food, and health security of human. Lignin and hemicellulose can be used for generation of biofuels and biofertilizer. Cellulose can be sustainably used for the production of nanosilica, biodegradable polymer, paper, pulp, etc. This chapter emphasizes sustainable agro waste management without affecting the environment at lower cost in timely manner. In particular, the agro waste biomass could be used as a source of value-added bio-product, which has wide applications and impacts the bio-economy without hampering the climatic change issue.

China is one of the world's biggest importers of agricultural products. Until quite recently, China's agricultural policy focused on food self-sufficiency. Globalizing trade in agricultural commodities, however, has brought new challenges to establishing secure supply and achieving security rather than self-sufficiency. In the face of emerging trade tensions with the USA, one of China's responses to the emerging volatility of the global market is to expand production facilities abroad and thus diversify deliveries. This chapter discusses how China's Belt and Road Initiative may serve improving food security of the country by establishing of a predictable system of agricultural production and trade across Eurasia, particularly, with the involvement of land-abundant Russia and the countries of Central Asia. The author explores possible responses to emerging threats to China's domestic food market by elaborating an approach to theoretical definitions and practical issues of ensurance of food security and adaptation of China's policy to contemporary global challenges.

The fermented beverages and foods either of plant or animal source play a vital role in the food of society in several parts of the world. The fermented of foods not only afford vital sources of nutrients but also have abundant potential in maintaining health and also preventing various diseases. The bacteria and yeasts are the major groups of microorganisms related to traditional fermented of the foods. Numerous diverse types of traditional fermented beverages and foods are formed at domestic level in the various countries. The advancement of fermentation technology provides value addition to waste food by their complete conversion into the different value-added products. The recent research suggests that the biological functions of fermented foods affect the health due to functional microbes involved during fermentation which provides several health-promoting benefits to the consumers. The emphasis of this chapter is to describe the fermentation technology and their potential to minimize the wastage of foods by conversion of value-added products and their benefits.

Full textAbstract:
Enterprises engaged in food production are one of the focuses of the European Green Deal, as the implementation of its objectives will make impacts on agriculture, which is one of the most important industries supplying raw materials to food producers, as well as on energy and transport. Previous research studies have emphasized that processes within the local food system (LFS) occur over a relatively short geographical distance, thereby creating a number of economic advantages as well as making a significant impact on the community economy. In other words, this diversifies the rural economy, makes enterprises more economically independent, develops local potential and contributes to the image of the area. Most of the food produced in Latvia was sold in the domestic market, and only approximately a third of the food output was exported over the last decade. The expansion of the domestic market is therefore very important for local producers. Food production is spread throughout the country, and both home producers and rural small and medium enterprises producing food participate in the market, which contributes particularly to the socio-economic viability of the population living in rural communities. As a result, local food systems emerge, which is a complex phenomenon, as it involves more than just economic aspects. Food production, distribution and waste management are indirectly affected by several public policies, as the food production begins with the exploitation of primary production resources linked to the environment and ends with the development of cultural services, including the preservation of traditions and values. Accordingly, it might be argued that an LFS represents a very complex and diverse set of actors and their interrelationships, which is constrained by specific social, cultural, economic and institutional frameworks, and therefore the research aims to give insight into the public policy dimension in food systems and, based on the research findings, identify key problems and develop recommendations for the development of food systems in Latvia.

In this work we estimate the amount of energy required to produce the food consumed in the United States in 2002 and 2007. Data from government sources and the scientific literature were used to calculate the energy intensity of food production from agriculture, transportation, manufacturing, food sales, storage and preparation. Most data were from 2002; consequently we scaled all data from other years to 2002 by using ratios of total energy consumption in 2002 to total energy consumption in the year data were reported. We concluded that food production required at least 7,880±733 trillion BTU in 2002 and 8,080±752 trillion BTU of energy in 2007, over a third of which came from food handling in homes, restaurants and grocery stores. The energy used to produce food represents approximately 8% of energy consumption. Our estimate is for the energy required to produce the food consumed in the United States and takes into account food imports and exports. To account for net food exports in the agriculture sector we calculated values for the energy intensity of ten food categories and then used the mass of domestic food consumption in each category to calculate the energy embedded in the food consumed in the United States. The amount of energy required to produce the food consumed in the United States has policy implications because it is a substantial fraction of total energy consumption and is responsible for a commensurate amount of greenhouse gas emissions. There are many opportunities for decreasing the energy intensity of food production at all steps of the food system. Education of the public and policy measures that promote energy efficiency in the food sector have the potential for decreasing food waste and the energy intensity of the food system.

Say the word “environment” today, and most likely you will generate some sort of a response. It’s one of our society’s hot issues and we have seen Washington, from President Bush on down, and many of our states and cities jumping on the environmental issue because there are real problems that need to be solved and, in addition, it appears to be good politics. Solid waste is part of the environmental issue and packaging is part of solid waste. So, I would like to take you through how we, at Continental Can, are looking at this. We are one of the leading packaging producers with seven domestic divisions producing aluminum cans, steel and bi-metal cans, PET plastic bottles, extrusion blow molded plastic bottles from HDPE, PP, PVC, with multilayers and multimaterial barriers, and thermo formed microwave trays and tubs and aseptic cups mostly made from plastic multimaterial barrier sheet which we extrude. Continental also annually produces over 6 billion metal vacuum “twist off” closures, some plastic closures and our Bondware division produces paper and plastic coated paper containers mostly or fast food outlets.

There is growing interest in innovative waste water treatment technologies that can utilize the inherent energy-producing potential of organic waste. A microbial fuel cell (MFC) is a type of bioreactor that produces electricity by converting energy in the chemical bonds of organic material, through a catalytic reaction of microorganisms under anaerobic conditions. MFCs provide a promising low cost, highly efficient, and renewable energy-producing alternative to conventional wastewater treatments. MFC technology at the laboratory scale has advanced to the point where chemical oxygen demand (COD) removal efficiencies (RE) over 90% are commonly achieved; however, low coulombic efficiencies (CE) and power densities often result when treating actual industrial and domestic wastewaters. In spite of their low energy recovery and power production, MFCs have been shown to be economically viable when factoring in costs savings from the sale of produced chemical byproducts and reduction of solid waste removal costs. However, further research of large-scale MFC wastewater treatment applications must be performed to determine the extent of their feasibility. This paper reviews several pilot-test MFC systems, addresses promising future industrial applications, and discusses current research gaps in MFC technology for wastewater treatment. Of particular interest in our research program is the use of MFCs to treat liquid-phase organic waste generated at food processing plants. Because of the general scalability of fuel cell systems, there is reason to believe that an MFC treatment system would be better suited to relatively small waste flow rates, unlike other treatment methods (e.g., anaerobic digestion) which typically require large volume to achieve economic viability.

Full textAbstract:
Abstract Recent interest in reducing stress on the food-energy-water (FEW) nexus requires the use of renewable, organic products that can subsequently address environmental sustainability concerns, such as mitigating greenhouse gas emissions. Pyrolysis-derived biochar from organic wastes (e.g., nutrient-rich agricultural wastes and leftovers, forest harvest residues, and cattle manure) and advanced feedstocks (e.g., algae) is capable of addressing ever-increasing global FEW concerns. Biochar water-nutrient holding capacity and carbon sequestration are key attributes for improving organic farming and irrigation management. The major challenge to commercialize biochar production from organic wastes is the conversion process. Pyrolysis process is a cost-effective and successful approach in comparison to other conversion technologies (e.g., gasification) due to low energy requirement and capital cost, as well as high process efficiency and biochar quality. To determine the environmental impacts of the biochar production process, an analysis of the material, energy, and emission flows of a small-scale pyrolysis process is conducted for a real case study, using life cycle assessment method with the assistance of available life cycle inventory databases within OpenLCA software. The results demonstrate that this study is able to enhance sustainability aspects across FEW systems by (a) employing a portable refinery to address upstream challenges (i.e., collection, transportation, and preprocessing) of waste-to-biochar life cycle, (b) recycling domestic forest and agricultural residues (e.g., pine wood), (c) producing organic biochar-derived soil conditioners that can improve organic cropping and FEW systems. Ultimately, we conclude by discussing techno-economic and socio-environmental implications of biochar production from organic wastes and advanced feedstocks.

Full textAbstract:
Surfactants are versatile and ubiquitous chemical compounds that find application in everything from laundry detergents to pharmaceuticals. Commercial production of anionic surfactants, which provide the foaming and soil removal properties consumers have come to enjoy in their cleaning and personal care products, is at the highest production volumes focused on several surfactants. These include the petrochemical-derived surfactant linear alkylbenzene sulfonate (LAS), as well as the partially biorenewable surfactant sodium lauryl ether sulfate (SLES) which has recently been the target of regulations due to the carcinogenic byproduct 1,4-dioxane. Oleo-furan sulfonate surfactants developed by Sironix Renewables provide a fully biorenewable anionic surfactant alternative without the carcinogenic byproducts, with performance in application testing which rivals or exceeds that of LAS and SLES, particularly in challenging application conditions such as with hard water. Recent developments in Sironix’s research have identified unique and finely-tuned surfactant structures that provide a combination of desired properties with application across a wide range of applications, including exhibiting superior foaming compared to LAS or SLES with a less irritating effect on the skin. Oleo-furan surfactants have exceptional solubility, allowing for formulation of more concentrated consumer products; the surfactants can also be produced and shipped in powder form, allowing for reduced fuel use during transportation and a resulting decrease in product cost and lifecycle carbon emissions. Herein, we provide an overview of the properties for oleo-furan surfactants with comparison to commercial anionic surfactants and take a closer look at how costs and carbon emissions can be reduced by their substitution. We also discuss ongoing research at Sironix to produce oleo-furan surfactants from domestic and abundant biomass sources, including sources that are non-food competitive and those derived from agricultural waste.
