Abstract:
Various attempts have been made to solve problems of abundant solid wastes in big cities. One approach is the utilization of domestic waste to make composite materials, such as particle board. To increase the attractiveness of the product in this study we develop prototypes of statues using composites of domestic solid wastes and then coated the statues using carboneus phosphor material to produce artistic color under ultraviolet illumination. The composite materials were derived from domestic waste such as leaves, paper, and plastics as a filler and polyvinil acetate as a matrix. The coated material was a luminescent colloidal carbon particles that have been synthesized from urea ((NH2)2CO) and citric acid (C6H8O7) using a simple heating method. The colloidan carbon emits a luminescence peak at around 457 nm (blue color) under UV illumination. The produced statue from the domectic wastes composites we simply coated by a mixture of epoxy resin and phosphor material. Under UV light, the statue surface shows a bluish white luminescence.

Abstract:
We report the synthesis of a composite from domestic waste with the strength of wood building materials. We used original domestic waste with only a simple pretreatment to reduce the processing cost. The wastes were composed of organic components (generally originating from foods), paper, plastics, and clothes; the average fraction of each type of waste mirrored the corresponding fractions of wastes in the city of Bandung, Indonesia. An initial survey of ten landfills scattered through Bandung was conducted to determine the average fraction of each component in the waste. The composite was made using a hot press. A large number of synthesis parameters were tested to determine the optimum ones. The measured mechanical strength of the produced composite approached the mechanical properties of wood building materials. A fire-retardant powder was added to retard fire so that the composite could be useful for the construction of residential homes of lower-income people who often have problems with fire. Fire tests showed that the composites were more resistant to fire than widely used wood building materials.

Abstract:
ABSTRACT This study focused on developing a sustainable composite material using metallic wastes of the iron-steel industry and plastic wastes of the plastic industry in order to reduce resultant waste from the production processes of various industrial products and to sustain waste management of these industries. In this study, different amounts of blast furnace dust (BFD), which is the major iron-steel industry waste and is used as filler for recycled low-density polyethylene (LDPE), was mixed with LDPE to produce the composite material. The morphology, mechanical, vicat softening temperature thermal conductivity, hardness and wear resistance properties of BFD filled LDPE composites were assessed. The increasing of BFD in recycled LDPE improved the heat resistance, increased thermal conductivity and wear resistance of composite materials. In addition, it was found that the composite materials had sufficient mechanical properties, when mechanical tests were evaluated. These results showed that the produced composite material could be used in buildings as a floor coating material and thereby saving raw materials and resources, as well as potentially reducing environmental problems.

Abstract:
Water-sachets made from low density polyethylene (LDPE) form a bulk of plastic wastes which creates environmental challenges, while certain species of plants like Imperata cylindrica constitute large portion of weeds on farm lands. As a technological approach to the reduction and utilization of these materials, composites of Imperata cylindrica (IC) particulate and synthetic polymer (from recycled waste water-sachets) were produced and evaluated for several mechanical and physical properties. The production of the composites and testing were done using the standard methods available in the literature. The results showed an increase in tensile modulus, hardness, impact strength, and water absorption of the composite in comparison with unreinforced polymer, as the IC particulate loading increased from 5 wt% to 30 wt%. However, there was a decrease in tensile strength, percentage elongation at break and density of the composite as the particulate loading increased from 5 wt% to 30 wt%. The combination of the recycled waste water-sachets and IC particulate is really promising for composites development. This creates opportunities to reduce LDPE wastes and add economic importance to an otherwise agricultural menace. It will mean creating an economic value from “wastes”.

In the present work, composite materials with a two wastes - waste goose feather as a filler and resinous waste from HMF production as a binder - have been developed. The mechanical properties and water sorption in dependence with feather/HMF resin composite content were studied. The composites containing 50% of feather have high strength properties up to 46 N/mm2 and low water sorption (lower 1%), which results in high water resistance. Due to these properties, they can become an excellent alternative to urea-formaldehyde resins and plastics based on them.

Abstract:
Technological parameters of receiving composites from Tetra Pak packaging waste are determined in the work. Physical - mechanical characteristics of the received composites are defined. The analysis of the received results showed that composites from Tetra Pak packaging waste have loose structure and lower strength properties, in comparison with cardboard. Introduction of polyvinyl acetate (PVA) suspension leads to an increase in density of composites and strength properties. Tensile strength increases by 1,9 times, but doesn't reach the level of tensile strength of cardboard composites. Application of hot pressing results in formation of denser composite, thus, tensile strength of a sample increases by 2,8 times. Cumulative effect of PVA glue and hot pressing leads to an increase of composite tensile strength by 5,9 times. It becomes significantly higher than the similar characteristic for a packing cardboard. According to the realized complete factorial (CF), the adequate regression equation was received. It shows that the strength of Tetra Pak wastes composites, in a greater degree, depends on the concentration of PVA suspension.

Abstract:
Proper disposal methods and solid waste management are necessary for all the processing industries such as leather, textile and chemical industry. In this regard, the present paper reviews in detail about the leather and textile waste fibre-polymer composites and nanocomposites as a viable solid waste management strategy. In the paper, several published papers and patents available in this area are reviewed in detail. This approach adopts confinement of leather or textile waste fibres in a polymer matrix as a composite. Nanocomposites of leather waste fibre and polymer with nano-particle reinforcement have been reported to have enhanced physical and other properties. This would not only solve the problem of the disposal issue regarding leather solid wastes containing leather or textile waste fibres, but also provide versatile composite or nanocomposite materials as “Wealth from Waste Approach”. The unique feature of the present analysis and the review paper is that both leather and textile waste management have been covered in the present approach for the first time.

Abstract:
Purpose In the current scenario, air pollution and soil pollution from the industries wastes are one of the major problems all over the world. Further, disposal of these wastes from industries are very costly. However, several attempts were carried out by various researchers in the past to use these wastes. One of the most common waste products is bagasse from sugar industries. These hazardous bagasse wastes lead to air and soil pollution. This study aims to recycle bagasse waste in the development of aluminium base composite as partial replacement of ceramic particles. Design/methodology/approach In the present investigation, recycled bagasse waste was used in the development of aluminium base composite as partial replacement of ceramic particles such as SiC, Al2O3 and B4C. Production industries of these ceramic particles (SiC, B4C and Al2O3) emit huge amount of greenhouse gases such as N2O3, CH4, CO2 and H2O. These green house gases produce lots of environment problem. Furthermore, production of these ceramic particles is also costly. AA6061 aluminium alloy was taken as matrix material. Composite material was developed using the stir casting technique. Findings Microstructure results showed proper distribution of bagasse ash and MgO powder in the aluminium base metal matrix composite. It was notified from analysis that minimum corrosion loss and minimum porosity were found for Al/2.5% bagasse ash/12.5% MgO powder composite. For the same composition, hardness and thermal expansion were also observed better as compared to other selected compositions. However, density and cost of composites continuously decrease by increasing percentage of bagasse ash in development of composite. Originality/value Results showed about 11.30% improvement in tensile strength, 11.64% improvement in specific strength and 40% improvement in hardness by using bagasse ash as reinforcement with MgO powder in development of aluminium base composite.

Abstract:
Leather buffing dust (BF) is a waste from tannery which is usually disposed on landfills. The interest in using wastes as fillers or reinforcements for composites has raised recently due to environmental concerns. This study investigates the potential use of BF waste as filler for a high density polyethylene matrix (HDPE). A series of HDPE-BF composites, containing filler concentrations ranging from 20 to 50wt%, were formulated, injection molded and tested. The effect of filler contents on the mechanical properties of the composites were evaluated and discussed. Composites with BF contents up to 30wt% improved the tensile strength and Young’s modulus of the matrix, achieving similar mechanical properties to polypropylene (PP). In the case of flexural strength, it was found to be proportionally enhanced by increasing reinforcement content, maintaining high impact strength. These composites present great opportunities for PP application areas that require higher impact resistance. The materials were submitted to a series of closed-loop recycling cycles in order to assess their recyclability, being able to maintain better tensile strength than virgin HDPE after 5 cycles. The study develops new low-cost and sustainable composites by using a waste as composite filler.

Abstract:
Many plant wastes are not currently used in production, they are disposed of in landfills or incinerated. The aim of this study is to develop a composite thermal insulation material from unused spinning waste of flax and cotton fibers and soft wood waste. Samples of thermal insulation materials from plant waste were made by drying using the technology of production of soft wood fiber boards. For composite board defined physico-mechanical characteristics and thermal conductivity. The experiment was carried out according to a second-order plan, regression models of the dependences of the material indicators on the proportion of the binder additive, drying temperature and the proportion of wood waste additives were developed. The study showed that composites from unused spinning waste of plant fibers and soft wood waste have the necessary strength under static bending, the swelling in thickness after staying in water is much lower in comparison with the performance of boards from other plant fillers. The coefficient of thermal conductivity of the boards is comparable with the indicator for mineral wool boards.

Abstract:
Composting is a sustainable method to deal with huge amount of daily organic waste due to its robustness and easy operation. However, food waste (FW) as the main material in composting has disadvantages such as the heterogenous properties, high foreign matters contamination, high moisture content, low C/N ratio, poor structure, low porosity and high acidity during the initial phase of composting. These shortcomings not only influence degradation efficiency but also cease the composting process. Therefore, a bulking agent is required to increase the porosity and adjust the moisture content as well as C/N ratio of the composting mixture (Wong et al., 2010). For previous research, sawdust (SD) and tree barks were commonly used as the bulking agent in composting system but the demand for sawdust and tree barks significantly increased the cost of the composting process, and this has stimulated the demand of alternative substitutes. Therefore, the ideal situation is to find the bulking agent which is not only suitable for composting but is also a waste. Traditional Chinese medicine is widely used nowadays and huge amount of residues are accumulated and treated in landfilling (Wang and Li, 2013). According to previous research, only 5% of the active ingredients can be extracted from the medicinal plants which means there are still a large fraction of active ingredients remain in the herbal residues (Wu et al., 2013). In addition to the bulking property of Chinese medicinal herbal residues (CMHRs), it is assumed mature CMHRs compost have the ability to hinder regular metabolic pathway of phytopathogens after land application (Bernal-Vicente et al., 2008). The first experiment of this study investigated the formula between food waste, sawdust and CMHRs in order to achieve efficient composting. The experimental results demonstrated positively the use of CHMRs is a suitable candidate to co-compost with food waste. In terms of biodegradation decomposition efficiency and compost maturity, the treatment 1:1:1 (FW: SD: CHMRs, dry wt. basis) showed the best performance among all treatments with 67% organic matter degradation and 157% seed germination index. Only well-matured composting product can suppress plant diseases in soil since it has some microorganisms which can inhibit phytopathogens. The treatment 5:5:1 (FW: SD: CHMRs, dry wt. basis) also reached maturity but with a longer composting period; however, it was the treatment which could accommodate the highest quantity of food waste. The log copy number of the bacterial population was 7-8 initially, which decreased and stabilized along the composting. Results revealed that the CHMRs can be used as a bulking agent with food waste, and a dry weight ratio of 1:1:1 (FW: SD: CHMRs) would be optimum to achieve higher organic decomposition and faster maturity. However, the initial lower microbial population in the treatment, though without any adverse effect on the overall microbial decomposition, will warrant further work to indicate the total population is not a practical means to illuminate the effective microbial decomposition. Besides, the advantage in using CHMRs will need further experiment to indicate its potential pathogen suppression capability. Humification during co-composting of food waste, sawdust and CMHRs was investigated to reveal its correlation with compost maturity. The huge decrease in the treatment 1:1:1 (FW: SD: CHMRs, dry wt. basis) of aliphatic organics in humic acids (HA) demonstrated the degradation of the readily available organics, while an increase in aromatic functional groups indicated the maturity of compost. Disappearance of hemicellulose and weak intensity of lignin in the CMHRs treatments indicated that the lignin provided the nucleus for HA formation; and the CMHRs accelerated the compost maturity. Humic acid to fulvic acid (HA/FA) ratio of 1:1:1 treatment was the highest at the end of composting and showed a clear correlation with compost maturity as also evidenced through the presence of higher aromatic functional groups in the HA fraction. Pyr-TMAH-GC-MS results indicated that dominant groups were aliphatic and alicyclic esters and ethers at the early composting stages in all treatments. Long chain fatty acids were broken down into smaller molecular compounds earlier in treatment 1:1:1 (FW: SD: CHMRs, dry wt. basis), resulting from the faster decomposition rate. The complicated ring-structure components appeared dominantly at the later phase of composting. The peak intensities in treatment 1:1:1 (FW: SD: CHMRs, dry wt. basis) indicated that the composts became mature earlier than the other two treatments. In brief, the treatment with dry weight ratio 1:1:1 had greatest humification degree with more cyclic structures and stable final products at the end of composting. Water and acetone extract of composts with food waste and CMHRs were tested with their antipathogenic effect on two kinds of commonly found phytopathogens, Alternaria solani (A. solani) and Fusarium oxysporum (F. oxysporum). Seventeen bacterial species and 22 fungal species were isolated and identified as prevalently existed microbes during composting process. The results of MIC50 indicated that the treatment with dry weight ratio 1:1:1 (FW: SD: CHMRs, dry wt. basis) required least concentration of composts extraction to kill half quantity of the phytopathogens, 16% for A. solani and 22% for F. oxysporum extracted by acetone. The phytopathogen suppression capacity of composts was partially due to antagonistic abilities from some of the isolated microorganisms as well as the inhibition of active compounds. As shown in the comparison, the interfere/compete between antagonistic microorganisms and target pathogens were more powerful than individually influenced by chemical compounds. However, the influencing factors should not be considered independently since antagonistic interactions between microbes in composts and phytopathogens are highly dependent on the abiotic properties of the composts and the alternative environment. In a word, the antipathogenic effects from composts were synergism of both antagonism and chemical factors. Suppressive capacity on phytopathogens is one of the major function of mature composts and the antipathogenic effect was stimulated when CMHRs was used as the bulking agent in composting process. The abiotic inhibitory rates of treatment 1:1:1 (FW: SD: CHMRs, dry wt. basis) indicated that more powerful bioactive components were remained at the end of composting than in the treatment 5:5:1 and control which had no CMHRs but plastic beads as the bulking agent. Hence sensitive and comprehensive analytical technique of ultra-performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC-QTOF-MS) was utilized to acquire a better understanding of the complicated structures of final composting products. Seven dominant among 22 active compounds with antibacterial/antifungal properties were obtained in the treatments with CMHRs while 17 kinds of compounds with higher contents were shared in all treatments, which should be derived from food waste. The bioactive components from CMHRs composting were mainly from the groups of alkaloids, flavonoids and coumarins. Mature composts were used as biofertilizer to protect plants (Brassica chinensis and Lycopersicon esculentum) from phytopathogenic infection. This study showed the crop yields were increased with the addition of mature CMHRs composts to acid soil, and 5% CMHRs compost was the optimum application rate, while at the higher application rate of 10% (dry weight basis, w/w) plant growth was inhibited which might be due to the higher salt contents and the phytotoxicity of alkaloids, flavonoids and coumarins in the CMHRs. According to the biomass results, Brassica chinensis was more sensitive to the inhibitory effect of phytopathogen inoculation, while nutrient supply was to a less extent due to the short growth period as compared to Lycopersicon esculentum. The present study showed clearly that mature compost provided Lycopersicon esculentum and Brassica chinensis sufficient nutrients such as nitrogen and phosphorus. Additionally, the advantage of using mature CMHRs compost as a soil conditioner was also observed for blocking phytopathogenic infection from plant roots. The mechanism was mainly derived from the bioactive components in mature CMHRs compost which inhibited phytopathogenic activities in soil. Many identified compounds were alkaloids, flavonoids and coumarins which have powerful antifungal and antibacterial abilities and most of them maintained during growth period though their amounts reduced greatly due to their photolytic and pyrolytic properties. Therefore, mature CMHRs compost can be the substitute to reduce the usage of fungicides and its associated environmental hazards. The present study demonstrates clearly the beneficial effects of using CMHRs as a bulking agent to co-compost with food waste with the additional phytopathogens suppression property. Therefore, it is concluded that Chinese medicinal herbal residues can be a good choice of bulking agent in food waste composting system. Organic matter degradation and humification process were accelerated by CMHRs addition and mature CMHRs compost had antipathogenic effect and protect plants from infection

Chan, Man Ting. "Optimizing food waste composting process in fed-batch composter." HKBU Institutional Repository, 2015. https://repository.hkbu.edu.hk/etd_oa/217.

Abstract:
Composting is considered as an effective and sustainable food waste treatment technology from the perspectives of volume reduction, stabilization and releasing the pressure on landfills. Community composter is a decentralized composting facility in fed-batch operational mode which is usually being installed in the backyard of institutes, hospitals, housing estate etc. to handle the food wastes generated daily. Albeit numerous operational issues including high initial acidity and oil content, poor decomposition and odor generation are commonly encountered in these facilities, which make it difficult to be accepted by the public. Therefore, the aim of the present study is to develop a composting mix formulation that can provide a solution to all these issues in a fed-batch food waste composting process. The first phase of this study aims at finding out an optimized formulation in a batch-scale food waste composting process through the use of alkaline amendments and microbial inoculum. For the first two experiments, artificial food wastes were prepared by mixing 1.3kg bread, 1kg boiled rice, 1kg cabbage, 0.5kg fully boiled pork and mixed with sawdust to obtain a C/N of 30 and adjusted moisture of the mixtures to 55%. The effect of different concentrations of zeolite compared to lime was studied in the first experiment. Zeolite was amended with food wastes and sawdust mixtures at 2% (ZI-2), 5% (ZI-5), 10% (ZI-10) to compare with lime in 2.25% (L-2.25) w/w (dry weight basis) and composted for 56 days. Results demonstrated that 10% of zeolite was optimal amendment rate compared to lower dosage of zeolite (2% & 5%) with stronger pH buffering capacity and greater decomposition efficiency. Addition of 2.25% of lime buffered the pH efficiently but increased the ammonia loss significantly which eventually reduced total nitrogen (TN) content of final product and posed odor emission problem. Amendment of 10% zeolite provided a higher adsorption affinity on ammonia resulting in 2.05% of TN value of final product which was higher than 1.72% of lime treatment. Furthermore, significantly higher seed germination 150% was achieved of ZI-10 compost compared to 135% of L-2.25 due to low ammonium content of product. The first experiment showed that application of less than 10% zeolite was not sufficient to buffer the acidity; as a result, organic matter decomposition was inhibited. However, the cost and reduction in treatment percentage of food waste in 10% application rate of zeolite is an issue of concern. To tackle this dilemma, food waste was amended with struvite salts at 1:2 molar ratio of MgO and K2HPO4 (Mg:P) with or without zeolite amended at either 5% or 10% amendment (Mg:P, Z5 + Mg:P & Z10 + Mg:P) and a control treatment with food waste only was also included. Results showed that treatment of Z10 + Mg:P was synergistically achieved of pH and EC buffering, and N conservation but not for the case of 5 % zeolite. Treatment of Z10 + Mg:P further reduced the N loss to 18% compared to 25% and 27% of Mg:P and Z5 + Mg:P respectively. However, there was insignificant difference in the final nitrogen content and decomposition rate among all treatments with struvite salts amendment. Comparing to the treatment of Z-10 of the first experiment to Z10 + Mg:P of the second experiment, Z-10 showed superior performance since better decomposition efficiency, shorter time to require to pass the GI (28 Days) and lower cost because of salts exclusion. To develop a multipurpose formulation for the fed-batch operational food waste composter, high lipids problem in food waste cannot be neglected because it is a critical factor to hinder the decomposition efficiency. Inoculation of oil degradative microorganisms was reported as an effective approach to facilitate the lipids. Therefore, the third experiment was to investigate the overall composting performance supplemented with 10% zeolite and microbial consortium. 10% zeolite with bacterial consortium significantly reduced the lipid contents from 7% to 1% compared to control treatments. Furthermore, treatments amended with 10% zeolite was proved to reduce ammonia emission and total volatile fatty acids level in the composting mass, therefore the total odor emission level can be reduced. Zeolite at 10% was found to be a suitable optimum additive for both synthetic and real-food wastes. Therefore, treatment of 10% zeolite with bacterial consortium is selected as an optimized formulation for further study of its application in a fed-batch composter. Following the food waste zeolite composting formulation obtained in Phase I, the aim of Phase II was to develop an ideal composting mix formulation for on-site commercial composters. Although the results have been demonstrated 10% zeolite with bacterial consortium facilitated the composting efficiency in batch composter, those amendments may be over-estimated if applied in a fed batch composter by using real food wastes. With this constraint, the applicability of these additives in commercial fed-batch composter needs to be assessed using locally generated food wastes. Treatments included food waste and sawdust mixtures at 4:1 mixing ratio (wet weight basis) were mixed with 2.25% of lime (L2.25), 10% of zeolite (Z10) and 10% zeolite with bacterial inoculum (Z10+O) and a control of food waste with sawdust mixture only was also included. 35 kg compost mixture was fed into each composter respectively daily for a period of 42 days. Only Z10+O was the most suitable composting mix for fed-batch food waste composting process with continuous sustained high temperature (55-60oC), optimal moisture (55%-60%), alkaline pH and low EC during the experimental period. Bacterial inoculum significantly improved the lipids decomposition from 22.16% (C) to 3.10% (Z10+O) after the composting period. In contrast, lime and zeolite alone treatments could not maintain the optimal pH that led to reduce degradation and longer stabilization period. Only compost taken from Z10+O treatment could be classified as mature compost. The aim of the third study phase was to examine an optimal application rate of food waste compost produced from decentralized food waste composter for plant. A plant growth experiment was conducted in this phase to evaluate the change in soil properties and plant growth of Brassica chinensis and Lycopersicon esculentum. The experiment was conducted in a loamy soil amended with 0%, 2.5%, 5% and 10% food waste compost amendment rate compared to the control soil with chemical fertilizer amendment only. Results indicated that 5% was the optimal application rate of food waste compost for both crops among all treatments which can be evidenced by the highest biomass production and nutrients value of the plant tissues. Plant available nutrients such as NH4+, NO3-, PO43- were proportionally increased with increase in compost application rate. However, 2.5% of the food waste compost did not provide sufficient nutrients for plant growth and 10% showed negative effects due to increased salts content. Plants amended with chemical fertilizer had relatively low biomass production compared to compost amended treatments due to soil compaction and fast leaching of nutrients. It can be concluded that application of 10% zeolite with microbial consortium is an ideal composting mix formulation for on-site commercial composters and 5% is an optimal application rate of food waste compost of Brassica chinensis and Lycopersicon esculentum

Abstract:
Buildings construction and realization of public infrastructures have always been a primary need in the human society, developing low cost and user-friendly materials which also encounter safety and durability requirements. Portland cement is the most used material in construction industry from the industrial revolution up to date, but the raising concerns related to the climate change are pushing the governments worldwide to replace it with more eco-friendly and greener materials. Geopolymers are considered to be best alternatives to Portland cement in construction industry, but issues related to cost and mechanical properties are still hindering the commercialization of this material. Geopolymer incorporating wastes is one of the solutions. Fly ash, a thermal power plant by-product, and borosilicate glass, a recycled glass from pharmaceutical vials, are suitable candidates in geopolymers activation. NMR and FTIR spectroscopies demonstrated that borates from borosilicate glass are active compounds in geopolymerization, substituting the alumina is its role, composing a B-Al-Si network never observed before. Various fly ash and borosilicate glass weight contents were studied in terms of mechanical properties (compression test, 3-point bending test). It was found that fly ash 55 wt.% and borosilicate 45 wt.% composition activated in 13 M NaOH solution holds the best compressive and flexural strength (45 and 4 MPa respectively), 25% stronger than similar counterparts found in literature. Cellulose fibres in different weight contents were dispersed into the geopolymeric paste to produce geopolymer composites, with the aim to render the material more suitable for structural applications. 3-point bending test showed an improvement of the flexural strength of about 165% (12 MPa), while the chevron notch method displayed a fracture toughness of 0.7 MPam1/2, in line with the results of geopolymer composites found in literature. In this thesis work, fly ash was also successfully densified in 3 M NaOH solution and distilled water through a new method based on hydraulic pressure, called hydro-pressure sintering. This innovative technology involves a drastic reduction of NaOH utilization in geopolymerization, rendering the material more eco-friendly. XRD spectroscopy conducted on produced samples revealed a higher formation of crystals, most likely induced by the application of hydraulic pressure (450 MPa).

Abstract:
In this thesis, a study was undertaken on the premise that the world population living in urban centers is expected to increase from 3.8 billion to 5.2 billion, from 2005 to 2025, representing 54% and 65% of total world population, respectively. The urban population (UP) growth will produce remarkable amounts of urban food waste (UFW) that will add more pressure on already overloaded municipal solid waste (MSW) management systems of cities. This problem is more serious in countries experiencing major economic growth such as China where UP is expected to increase from 44% to 66% of the total country population, from 1995 to 2025. Asia produces the largest amount of UFW, which is expected to increase from 251 million ton to 418 million ton (45% to 53% of total world UFW) from 1995 to 2025. On site treatment of UFW along with a limited movement of world population from rural to urban areas are suggested to reduce pressure on MS W management system for the upcoming decades.
In this thesis, a project was also undertaken to develop compost recipes for urban center such as downtown Montreal. Monthly (June to August) average residential FW production was found to 0.61 (+/-0.13) kg capita-1 day-1 and that of a restaurant was found to be 0.56 (+/-0.23) kg customer-1 day-1. From trial tests, the best compost recipes mixed 8.9 kg, 8.6 kg and 7.8 kg of UFW for every kg of wheat straw, hay and wood shaving, on a wet mass basis. However, quantity and characteristics of FW vary from one month to another; therefore, regular adjustment of compost recipe is recommended. When using wood shavings as bulking agent, it is strongly recommended to correct the acid pH.

Abstract:
AbstractPoor municipal solid waste management continues to be a daunting issue for municipal authorities in Ghana. Major cities generate 2000 tonnes of mixed municipal waste per day, of which about 80% is collected and disposed of at open dump sites and/or at the limited number of landfills available. About 60% of this waste is organic. The Utilization of Organic Waste to Improve Agricultural Productivity (UOWIAP) project sought to co-create knowledge through a private-public engagement for the development of organic waste value chain opportunities to sustainably manage municipal organic waste and, at the same time, improve urban farm soils and increase food productivity in the Ga-West Municipal Assembly in the Greater Accra Region of Ghana. Through the project, identified key stakeholders in the waste and agricultural sectors, such as market traders, informal waste collectors, unemployed persons, farmers, landscapers, media, agricultural extension officers, Municipal Assembly officers and the general public, were engaged and made aware of sustainable organic waste management processes, including organic waste segregation from source, collection and compost production. Four formal markets were selected for the piloting of organic waste segregation from source. Interested persons were trained in organic waste collection, compost production and entrepreneurship. The lessons learned draw attention to the need for a massive effort to generate demand for compost use as this will invariably drive removal of organic waste from the unsorted waste stream.

Abstract:
AbstractCompost is a widely accepted organic fertiliser throughout the world. It is being produced using a wide variety of source materials at household to commercial scale. With the increased population and changes in food consumption pattern tending towards a vegetable- and meat-rich diet, the amount of organic waste generated in urban and peri-urban settings has increased. Many governments promote composting as a process that helps them to reduce the volume of organic waste and recycle nutrients back to croplands. Some examples of organic waste accumulated in large scale include household waste from urban and peri-urban settings, sewage, animal farm waste, agricultural waste from large-scale markets, food debris, and kitchen waste from hotels. The composition of compost varies in a wide range depending on the nature of materials used to produce it. The safety concerns related to compost also vary along the same line. The quality of compost has become a subjective term that means different aspects to different bodies due to a lack of commonly agreed standards to regulate the composting process and the final product itself. Recent research findings indicate that compost can serve as a carrier of potentially toxic trace elements, organic pollutants, and determinants of antimicrobial resistance to the environment and along the food chain. Producing good-quality compost safe to human health and the environment at large has become a challenge that should be addressed at various levels: from production to policymaking. This chapter discusses some of the major challenges faced in Sri Lanka with compost making. To prepare the background for this discussion, information on the policies and current practices of nutrient management in Sri Lanka is also presented. The context may be applicable to many other developing countries in the tropics.

Abstract:
AbstractMunicipal solid waste (MSW) generated in developing countries usually contains a high percentage of organic material. When not properly managed, organic waste is known for creating many environmental issues. Greenhouse gas (GHG) emissions, soil and water contamination, and air pollution are a few examples. On the other hand, proper and sustainable management of organic waste can not only bring economic gains but also reduce the waste volume that is sent for final disposal. Composting is one such recovery method, in which the end product – compost – eventually helps the agricultural industry, and other sectors, making the process an excellent example of nexus thinking in integrated management of environmental resources. The aim of this chapter is to discuss how Cajicá, a small city in Colombia, approached this issue in a methodical way to eventually became one of the leading organic waste composting examples in the whole world, as recognised by the United Nations Environment Programme in 2017. Cajicá launched a source separation and composting initiative called Green Containers Program (GCP) in 2008, based on a successful pilot project conducted in 2005. The organic waste separated at source collected from households, commercial entities, schools, and universities are brought to a privately operated composting plant chosen by the city to produce compost. The compost plant sells compost to the agricultural sector. The participants in the GCP could also receive a bag of compost every 2 months as a token of appreciation. The Cajicá case presents us with many lessons of good practice, not only in the sustainable management of waste but also in stakeholder engagement. It specifically shows how stakeholders should be brought together for long-lasting collaboration and the benefits to society. Finding the correct business model for the project, efforts made in educating the future generation, and technology adaptation to local conditions are also seen as positive experiences that others can learn from in the case of Cajicá’s GCP. Some of the concerns and potential threats observed include the high dependency GCP has on two institutions: the programme financially depends completely on the municipality, and the composting operation depends completely on one private facility. GCP will benefit from having contingency plans to reduce the risk of having these high dependencies.

Abstract:
The aim of this paper is to obtain and study the properties of wood waste reinforced elastomer composites with various fibre contents (10-50 wt%). The composite is based on chloroprene rubber, and added post-consumer recycled wood particles, with dimensions of 500 nm eco-reinforcing material, and active fillers, plasticizers, vulcanizing agents, antioxidants. In order to enhance the compatibility and their level of interaction, the wood waste was finely ground (cryogenic mill) and functionalized with potassium oleate. Wood waste acts as a filling material which leads to the biodegradability of the composite and the decrease in density. Tensile, tear strength, elasticity, hardness, abrasion resistance, melt flow index and morphological study (FT-IR) of those composites were examined in order to determine the viability in various applications domains.

Abstract:
The article deals with the issues of secondary use of industrial waste from the processing of soft hardwood wood. It is shown that the disposal of man-made waste in landfills is undesirable, and the use of wood waste to generate heat for heating is limited to the autumn-winter period. It is proved that it is most expedient to make composites from the waste of processing soft hardwood wood, since the need for inexpensive building materials is constantly increasing. Wood- cement materials from soft-leaved wood are practically not produced due to the presence of water- soluble saccharides, which worsen the process of hydration of cement. It is proposed to use binders that harden quickly in the production of composites made of soft hardwood. To exclude the negative influence of the extracted substances, it is proposed to use urea-formaldehyde glue as a binder. The mathematical dependence of the compressive strength of a composite made of soft hardwood on the glue consumption, wood consumption and the duration of exposure after molding is obtained. The parameters of the composite manufacturing mode are set: wood consumption-190 ... 195 kg/m3, urea-formaldehyde glue consumption-262...270 kg/m3; the duration of exposure after molding – 6 days. Methods for reducing the release of free formaldehyde from composites have been identified. It was found that in the steam-air mixture after 12 days of exposure of the chip-and- glue composite, there are no previously detected micro-impurities of formaldehyde, and the chip- and-glue composite can be used in construction without restrictions.

Abstract This study investigates virgin and recycled high-density polyethylene/multi-walled carbon nanotube (HDPE/MWCNT) composites using thermo-physical and mechanical characterization techniques to generate knowledge and understand recyclability of these composites. Firstly, virgin samples with 0.1–5 wt.% of MWCNTs were prepared by injection molding. Then, the HDPE/MWCNT composite waste was mechanically recycled and consecutively reprocessed by injection molding. The experimental results show that, after the first mechanical recycling and reprocessing cycle, the thermal, rheological, mechanical, and electrical properties for the recycled and virgin HDPE/MWCNT composites with 0.1–3 wt.% were rather similar within the experimental error of the measurements. In contrast, the recycled HDPE/MWCNT composites with 5 wt.% showed a reduction in viscosity, mechanical and electrical properties with recycling. After four recycling and reprocessing cycles, degradation in the Young modulus (−35%), tensile strength (−25%), elongation at break (−60%) and electrical conductivity (−2 orders of magnitude) of the HDPE/MWCNT composite with 5 wt.% was observed as compared with the virgin composite. From an industrial perspective, it is feasible to recycle HDPE/MWCNT composite waste by mechanical recycling and use it to manufacture products with favorable mechanical properties, covering insulating, antistatic and semiconducting ranges depending on the MWCNT loading, owing to the protective effect of carbon nanotubes against thermomechanical degradation.

Abstract Fast growing plants or biomass wastes can be used as affordable and environmentally sustainable alternatives to synthetic insulation materials. The aim of this study was to investigate the mechanical properties (tensile strength and Young’s modulus) of natural fiber reinforced polymer composites as potential building materials. As a natural fiber, Bermuda grass seeds, conifer cones and pinecones are selected. The fundamental processes to develop nanofiber reinforced resin by processing agricultural waste fibers into nanocellulose is also investigated. Tensile tests are conducted to define stress/strain relationship. SEM tests are conducted to evaluate the surface topologies after fracture. The tensile fracture surfaces of composites were investigated. With the addition of Bermuda fibers, the stiffness of the vinyl ester sample was observed to increase by 624.2% compared to neat vinyl ester sample. With the addition of nanocellulose fibers, the stiffness of the composite was observed to increase by 53.3% compared to neat vinyl ester sample.

Abstract:
In this study, a numerical representative volume element (RVE) model was used to predict the mechanical properties of a Rice Husk Particulate (RHP)-Epoxy composite for use as an alternative material in non-critical applications. Seven different analytical models Counto, Ishai-Cohen, Halpin-Tsai, Nielsen, Nicolais, Modified Nicolais and Pukanszky were used as comparison tools for the numerical model. The mechanical properties estimated for 0%, 10% and 30% RHP-Epoxy composites using the numerical and analytical models are in general agreement with each other. Using the analytical models, it was calculated that an increase in volume percentage of RHP to 30% led to continual reduction in elastic Young’s modulus and ultimate tensile strength of the composite. The numerical RVE models also predicted a similar trend between filler volume percentage and material properties. Overall, the results of this study suggest that RHP can be used to reduce the composite raw material costs by replacing the more expensive polymer content with agricultural waste products with limited compromise to the composite’s mechanical properties.
