Abstract (sommario):

Reducing carbon footprint is a trend within modern green restaurants. A carbon footprint is the total set of greenhouse gas (GHG) emissions caused by an organization, event or product. Food and beverage restaurants have to deliver food using a minimal carbon footprint. Of previous researches, only a small fraction is focused on reducing carbon footprints in a culinary room. Besides, a carbon footprint cost model was hard to solve in economic computation time. Therefore, the main purpose of this research is through a distributed information system to accelerate computing ability of a carbon footprint cost model. Through the distributed computing, our experimental results showed that the proposed approach outperformed the literature approach efficiently. The algorithm improved rate was 68.6%, and low down 82.1% carbon footprint than manual. The proposed approach could contribute to accelerate calculations in others problems due to using multiple machines in future researches.

Abstract (sommario):

The National Tourism Conference in 2010 strongly promoted the concept of energy conservation and emission reduction in the tourism industry. Since then, low carbon travel has been the new direction in tourism industry. Great concern has been put on energy conservation and emission reduction of tourism related elements, such as hotels, transportations, tourist attractions, and most importantly, the tourists themselves. The quantitative assessment of tourist carbon footprint is the key topic. This research uses Yesanpo scenic area as the example and conducts the comparison and calculation of tourist carbon footprint from different places, attempts to organize different ideas on ways to analyze tourist carbon footprints, constructs a calculation and assessment model, analyzes and measures the levels of tourist carbon footprints from diverse modes of travel, origins, and purchasing power. This research has developed a system for quantitative assessment of tourist carbon footprints, with the hope of strengthening the theories and methods on low-carbon travel.

Abstract (sommario):

Using an imported timber-based solid wood box bed (2000 mm × 1800 mm) as the functional unit, the ILCD 2011 midpoint assessment method was used to measure the life cycle carbon emissions of the product. Using this assessment, the Dijkstra algorithm was adopted to determine the shortest supply chain path and to obtain the minimum carbon footprint of the supply chain. Results showed that the total carbon footprint of the wood bed was 464 kg for the control case. For experimental cases, the carbon footprint ranged from 456 kg to 517 kg CO2-eq. The upstream process was identified as the primary contributor to the carbon footprint, accounting for 74.6% to 80.7% of the total carbon footprint, followed by the downstream and the core-stream processes. Configuration of a timber harvesting system with lower fuel consumption, purchasing timber from areas within shorter transportation distance, and reducing the proportion of incineration for waste treatment were feasible solutions to reduce the carbon footprint of the product. A case study optimizing the low-carbon path for the wooden furniture supply chain determined the shortest path for the participants in each link, such that the minimum total carbon footprint of the supply chain was 463 kg CO2-eq.

Abstract (sommario):

Based on the data of provincial input-output model and the carbon footprint model, the analysis is focused on provincial carbon footprint and the space transfer of carbon emissions. The results have shown that: (1) There are significant differences of provincial total carbon footprint amounts: resource-rich provinces have high total carbon footprint amounts, followed by processing and manufacturing provinces and municipalities; Regions with high energy efficiency have low carbon footprint amounts, so does southwestern region where economic and industrial development level is relatively low. (2) The provincial differences of carbon footprint per capita are related to demand structure: the amounts of carbon footprint are high in provinces with higher demand of consumption and investment, especially those provinces with strong demand for construction and processing industries. The amounts of carbon footprint are low in provinces which are non-resource-based, have limited investment and construction, and its economic structure is not dominated by processing and manufacturing. (3) Interprovincial trades have a significant impact on carbon footprint and carbon emissions. Provinces with well developed infrastructure have net CO2 emissions flow-in that are directly induced by high energy consumption products; southwestern region, where processing and manufacturing industry is relatively less-developed, has main CO2 emission flow-in, which are induced by the demand of processing and manufacturing industries; resource-intensive provinces and provinces with well-developed processing and manufacturing industries have net CO2 emission flow-out, which are induced by interprovincial trades.

Abstract (sommario):

The investigators have tried to know the awareness and practices of Postgraduate students studying in various streams of education at the University of Balasore, Odisha, India in reducing carbon footprint. In this study investigators used the stratified random sampling method to select the sample consisted of 180 students, comprising both female and male students. In the study data was collected by using Carbon footprint awareness test and Carbon footprint practices scale constructed by the investigators themselves. The findings revealed that more than half of the students had low level of carbon footprint awareness; whereas no significant difference was found between female and male students in their level of carbon footprint awareness; however students who followed different academic courses had varying degrees of awareness of their carbon footprint. The findings also revealed that half of the students had low level of carbon footprint practices and there exists a statistically significant difference in the mean carbon footprint practice scores of postgraduate students from different streams of education. There is a correlation between carbon footprint awareness and carbon footprint practices as viewed by the postgraduate students. Thus, it can be inferred that as the awareness of carbon footprint increases among postgraduate students, their implementation of practices to reduce carbon footprint also increases.

Abstract The paper aims to study the importance of low-carbon landscape design based on rural tourism landscape. First of all, after sorting out and researching the relevant reviews of low-carbon landscapes, taking rural landscapes as the research object, a rural landscape planning and design framework based on the perspective of low-carbon construction is proposed. Then, Xiwuli Village is used as an example to carry out the application practice of specific strategies and the carbon emissions before and after the planning and design are calculated and compared. After the low-carbon planning and design of the rural landscape, the net carbon footprint and the total carbon footprint were significantly reduced, confirming the low-carbon effect of the planning and design strategy. Finally, according to the actual situation of the scenic spot, it points out the principles and policy suggestions that must be followed in the development of low-carbon rural tourism. Experiments show that: the net carbon footprint and total carbon footprint are significantly reduced, which proves the actual effect of low-carbon design and the effect of low-carbon planning and design strategy.

Abstract (sommario):

The carbon footprint of motorized transport modes per unit length traveled encompasses the unit share of the vehicle lifetime emissions, that of the transport infrastructure, and those of the motor energy, considered both from “well to tank” and from “tank to wheel”. In the active modes of transport, i.e., walking and cycling, the counterpart of motor energy is human energy, which is associated with two kinds of carbon flows: the carbon footprint of food intake, – which we call the Food to Body component – and the carbon dioxide emissions of respiration – say the Body to Foot component. In this article, we provide a model in simple mathematical form to assess those carbon flows per unit length. It involves the modal speed in (i) the Metabolic Equivalent of the Task (MET) which gives rise to the energy and carbon flows, and (ii) the ratio of time spent to length travelled. The two influences of speed onto a modal carbon footprint combine in the net MET per unit length, with some compensation. The carbon footprint of food intake varies widely depending on the food diet of individuals. In a numerical study, the Food to Foot carbon emission of walking, cycling, e-scooter riding, and driving a car are estimated and compared to the rest of modal carbon footprint. Under conditions typical of France in the 2010s based on the average food diet and low carbon intensity of electricity, the inclusion of F2F in modal footprints changes the ranking of the modes according to the carbon footprint per unit length.

Abstract (sommario):

The emissions associated with food consumption make up approximately 20-30 percent of Scotland’s total greenhouse gas emissions (GHG). Reducing demand for high carbon footprint food products may provide an effective instrument for reducing GHG emissions. However, there is concern that using consumption based taxes may also have negative consequences on nutrition. Therefore, this thesis investigates the likely effect of carbon consumption taxes on GHG emissions and the resulting impact on nutrient consumption. The data used for the analysis are the Scottish part of Kantar Worldpanel data for the UK for the period 2006-2013 along with various sources of carbon footprint and nutrient data. This thesis models a carbon consumption tax which is based on the carbon footprint of the products of interest. The impact of the taxes on demand for food products were measured through the use of demand systems. Two forms of demand systems were used: Almost Ideal Demand System (AIDS) and an Exact Affine Stone Index (EASI) which allow for the estimation of price elasticities based on time series data. These Marshallian price elasticities were then used for estimating carbon footprint and nutrient elasticities which allow for the estimated change in GHG emissions (represented as carbon emissions) and nutrients. The price elasticities were particularly important for identifying the substitutes and complements of the different food products. This is useful as some food products such as poultry have a lower carbon footprint relative to beef products. The results suggest that applying carbon consumption taxes would likely reduce carbon emissions though the reduction is relatively small. The net effect of taxing all major food products would likely reduce emissions by 543,208.75 tCO2e/y which represents approximately five percent of the total emissions in Scotland attributed to food consumption (no land use change considered). However, taxing only meat and milk food products could reduce emissions by approximately 1.6 million tCO2e/y. While this reduction is much larger than when all food products are taxed, it is considered that modelling all the major food products offers a more realistic understanding of how households will change their demand for the different food products. The effect on nutrient consumption with regards to taxing all food products suggests that households with lower socioeconomic status would likely experience some favourable changes in terms of a reduction in sugar and energy. Though a negative distributional effect is likely to occur when considering the decreased consumption of vitamin D and the increased consumption of salt. Therefore, a carbon consumption tax is estimated to reduce food based GHG emissions by a relatively small amount. Despite the mainly positive effect on nutrient intake, policy makers are still likely to be cautious when considering this instrument because of the relatively small (compared to other studies) reduction in GHG emissions.

Abstract (sommario):

Yes
The UK faces the joint economic policy challenges of raising productivity and tackling climate change. This report challenges prevailing narrow market-based views of productivity, by examining the £4bn UK early stage Cleantech innovation finance market. We find that Cleantech innovation is frequently capital intensive and long horizon (5-10+ years), measured by shorterterm technology readiness level (TRL) and intellectual property (IP) progression. Longer-term sustainable productivity impacts remain little understood and, where applied, narrowly relate to customer adoption. This leads to Cleantech environmental impact investor logics that primarily relate to end user financial value (customer sales). There is little consideration for non-market values from, for example, circular economy (CE) and wider environmental spillover impacts (e.g. supply chains). Whilst few Cleantechs currently successfully commercialise, a small proportion exhibit high employment and sales growth and global environmental impact. Improved understanding of the broader environmental impacts of Cleantechs, through the adoption of environmental impact metrics (EIMs) can (i) add to a more holistic notion of productivity and (ii) improve the efficiency of the finance escalator, enabling more Cleantechs to contribute significantly to establishing the UK as a globally leading low carbon economy.

Abstract (sommario):

Climate change has emerged as one of the most serious challenges faced by human beings. As manufacturing globalisation involves more and more emerging nations, a greater proportion of CO2 emissions is generated from developing countries. The dilemma between fast industrial development and carbon reduction makes firms in developing nations reluctant to take serious commitment and actions in CO2 emission reduction in their global manufacturing practices. From a theoretical perspective, low-carbon supply networks research is also still in its infant stage and needs more explorations and development. Therefore this research aims to address the research question: “How can supply networks in developing countries be developed to reduce carbon emission?” Especially it focuses on: • An influence process to engage companies in developing countries to reduce carbon emission • A typology of carbon emission assessments in supply networks • An initial process of implementing carbon-reduction projects in supply network The research adopts theory building approach based on multiple case studies. The units of analysis are carbon reduction project of focal firms and initiatives of Non-Government Organizations (NGO). Drawing upon the cases, this research develops a general framework for developing low-carbon supply network, including three parts namely network influence, network CO2 measurement, and network CO2 improvement (IMI), with the three process models accordingly proposed. In the ‘influence’ process, based on resource dependence theory (RDT), this research illustrates a categorization of influence choices and a typology of influence pathways, which both underpin the four-step influence procedure proposed later. In the ‘measurement’ process, this research proposes a goal-oriented carbon footprint measurement guideline. In the “improvement’ process, an initial framework to classify carbon reduction projects and implementation process model of these projects are both built based on the analysis of primary case studies and Carbon Disclosure Project (CDP) database which contains corporates’ carbon reduction practices. Overall this research makes contributions in the following aspects: (1) this research advocates IMI framework as a pathway to de-carbonize supply networks, contributing to manufacturing system’s evolution to sustainable paradigm; (2) It integrates the institutional, stakeholder and network theory in the context of de-carbonization, and extends the research scope of operations management; (3) The research contributes to life cycle assessment (LCA) literature by exploring supply network coordination during the LCA procedure; (4) The research also contributes to green supply chain literature by providing insights from firms’ de-carbonization projects in supply network. (5) In practice, the IMI three-process models can help practitioners to implement de-carbonization management, serving as a preliminary guideline to follow. The potential audience of this research can be MNCs, NGOs, government bodies, consultants, and any organization or individual who aim to change industrial system in the pursuit of climate change mitigation.

Abstract (sommario):

Today we are experiencing an "eco friendly boom"; which includes the developing of ecological processes that have a smaller impact in the environment. This is the reason that prompted me to carrying out this thesis; the aim is to use a vegetable extract as a sustainable product for the pre-tanning processes. This study considers the use of the fruit of the Tara tree as a raw material source of tannins with low carbon footprint and proposes alternatives to avoid or reduce the use of commercial vegetable extracts, synthetic products and mineral salts that require non sustainable processes. Various experimental designs have been developed as to obtain new tailored Tara tannins by both chemical and physical modification, in order to obtain a higher percentage of tannins, and therefore improve its tanning capability, also reducing the astringency and improving the penetration of the tannin molecules through the leather structure. In chemical modifications, several aqueous extractions at different temperatures and combined with some chemicals, have been developed and optimized in order to increase the tannin content and reduce the astringency. The degree of hydrolysis has controlled by measuring the Gallic acid content by means of HPLC (High performance liquid Chromatography). In the physical modification part, the Tara has been milled and sieved, at several particle sizes, with the aim of obtaining a smaller molecular size. Both chemical and physical modifications were tested in hides, in a wet-white pre-tanning process, combining them with the fewest possible commercial vegetable extracts and syntans. The formulations have been optimized by experimental design. All the resulting leather products and final baths have been analyzed with physical and chemical tests respectively, to determine if they comply with the parameters established by the IULTCS (International Union of Leather Technologists and Chemists Societies). Finally, a life cycle assessment has been developed, in order to determine the environmental improvement of the new modified product, obtained in this thesis. This thesis is also supported with articles published in magazines specialized in the Leather sector.

Abstract (sommario):

Achieving the carbon emission reductions necessary to address climate change is proving challenging. Voluntary behaviour change by individuals has the potential to make a substantial contribution to decreasing carbon emissions, but generally that potential is not being realised. Group-based interventions, however, may offer an effective method for promoting significant and durable changes in pro-environmental behaviour leading to carbon reductions. This thesis evaluates Footpaths, a group-based programme designed and implemented by Transition Leicester and consisting of seven sessions. The study investigates the effectiveness of the programme, using a longitudinal mixed-methods approach to facilitate understanding of both measurable results and the processes leading to those results. The Reasonable Person Model (RPM) is used as a theoretical framework to aid understanding of the way in which group-based interventions may promote pro-environmental behaviour. Data were collected from participants just before and immediately after involvement with the Footpaths programme, as well as a year after the sessions commenced. Questionnaires were administered at all three times and semi-structured interviews were conducted after the last session. Participants also completed a carbon footprint calculator at all three times and provided data on measured energy use. Findings show that Footpaths participants reduced their carbon footprints by 15 percent over the course of the sessions, and continued to reduce their carbon footprints resulting in a 20 percent reduction over the course of a year. Pro-environmental behaviour increased, including increases in harder to change behaviours, and measured energy use decreased. Increases in pro-environmental behaviour and reductions in carbon footprint were associated with increased understanding, greater feelings of competence, and reduced confusion; all considered to be elements of a supportive informational environment. Participants highlighted the importance of having an opportunity to examine their own behaviour coupled with active engagement with information over a period of time. Neither feedback nor a desire for social contact were related to increases in pro-environmental behaviour. Pro-environmental behaviour was more closely associated with both worldview and attitude after participation in Footpaths possibly indicating a closer alignment between attitude and behaviour after participation. This research suggests that group-based interventions are effective in promoting significant and durable changes in pro-environmental behaviour and it provides interesting insight into the design of successful interventions to encourage such behaviour. Findings highlight the potential value of the RPM as an integrative framework for understanding the characteristics of interventions that successfully promote durable sustainable behaviours.

Abstract (sommario):

The aim of the research was to investigate how to stimulate sustainable consumer behaviors that lead to a lowering of the carbon footprint. Because of environmental challenges at the individual and societal levels, researchers agree that behavioral change is necessary. We argue that when already performing a sustainable behavior, this behavior can spill over to other sustainable actions, even to more difficult ones. First, we studied whether a positive behavioral spillover occurs between product categories and whether the spillover effect depends on the ease or difficulty of the sustainable behavior. Second, we investigated whether high awareness of sustainability determines the spillover between categories. We conducted three online experiments in Central Europe, investigating whether spillover takes place between behaviors assigned to the same category (transport or food) or between behaviors assigned to different categories (transport or food). In all three studies participants had to make two independent decisions. In studies 1a (N=281) and 1b (N=195), the effect of the ease/difficulty of the behavior was tested. In study 2 (N=164), awareness of CO2 emission reducing effects was manipulated. Findings revealed a behavioral spillover between sustainable choices.

Abstract (sommario):

One of the greatest challenges of our time is the ongoing climate change. Research suggests that it is us humans that through our greenhouse gas emissions are the greatest cause of globalwarming and the problems that comes with it. To reduce the emissions of greenhouse gas and meet the international goals, it is necessary for individuals to make changes in their behavior. Some people care a lot about the climate and tries to do everything in their power to lower theirown impact, others want to do something but do not know what and some people does not care at all. The purpose of this study is to provide a deeper understanding of how to influence people to live in a more environmentally friendly way by identifying factors that determines environmentally friendly actions both positively and negatively. The study was conducted through a qualitative case study where the data collection was made through personal interviews with citizens in Luleå. The results of the study show that knowledge has a strong connection to individual behaviors. It is important to know that the environmental actions you take is of importance. Many people have the desire to do more than they do but are hindered by contextual factors like saving time. Except for the factors that was identified in the frame of reference the study also shows that there are other reasons for individuals to act in an environmentally friendly way: health, economy, ethics, frugality and care about future generations. By identifying these factors and get an explanation of how they impact individuals, the study can aid decision makers of a county with information that helps them adapt their conversion work to the citizens. The recommendations for counties are to provide citizens with clear information both regarding what goals they aim to reach as well as concrete actions to take in order to fulfil these, make it easier to choose environmentally friendly options, market the environmental benefits but also other reasons for certain behaviors since many people are more motivated byother things than environmental reasons, share their results in their environmental work to include citizens as well as spread motivation for further behavior changes.
En av vår tids största utmaningar är de pågående klimatförändringarna. Forskning visar att det till allra största del är vi människor som genom våra utsläpp av växthusgaser är ansvariga för den globala uppvärmningen och de problem som den för med sig. För att reducera utsläppen av växthusgaser och uppnå de internationella utsläppsmålen krävs delvis insatser på individnivå. Vissa människor bryr sig mycket om klimatet och försöker göra allt i sin makt för att minska sin egen klimatpåverkan, andra vill göra något men vet inte vad och vissa bryr sig inte alls. Denna studie syftar till att ge en djupare förståelse för hur man kan påverka människor att leva mer klimatsmart genom att identifiera faktorer som påverkar miljövänliga beteenden i både positiv och negativ riktning. Studien genomfördes genom en kvalitativ fallstudie där datainsamlingen gjordes genom personliga intervjuer med invånare i Luleå kommun. Studiens resultat visar att kunskap har en stark koppling till en individs beteenden. Det är viktigt att de insatser man gör till förmån för klimatet känns betydelsefulla. Många har en vilja att göra mer för klimatet men hindras av kontextuella faktorer, till största del handlar det om tidsaspekten. Förutom de faktorer som identifierades i det teoretiska ramverket framkom även ytterligare orsaker till varför individer beter sig miljövänligt: hälsa, ekonomi, etik, sparsamhet samt att värna om framtida generationer. Genom att identifiera dessa faktorer samt få förklarat hur de påverkar individen kan studien bidra med information till beslutsfattare exempelvis inom kommuner för att de ska kunna anpassa sitt omställningsarbete till medborgarna i kommunen. Studiens rekommendationer för kommuner är att de bör bistå med tydlig information till invånarna, både när det gäller vilka mål de siktar till att uppnå samt vad som konkret krävs för att uppfylla dessa. Kommunen bör också göra det lättare att välja miljövänliga alternativ, marknadsföra såväl klimatnyttan men även andra skäl till ett visst beteende eftersom att många motiveras mer av andra fördelar än klimatnytta. Samt dela med sig av resultat i klimatarbetet för att göra medborgarna delaktiga samt sprida motivation att arbeta vidare.

Abstract (sommario):

Geopolymer material using by-products can lead to a significant reduction of the carbon footprint and have positive impact on the environment. Geopolymer is recognized as an alternative construction material for the Ordinary Portland Cement (OPC) concrete. The mechanical properties of geopolymer concrete are superior for normal exposure environments. In terms of durability in the seawater, a limited number of publications were available. The seawater environment contains chloride ions and microorganisms that are harmful for reinforced concrete structures. Hence, a study of the durability of fly ash geopolymer concrete is essential when this material is to be used in a real application. The present study aims to investigate the durability of fly ash geopolymer concrete mixture in a seawater environment such as seawater resistance and corrosion of steel reinforcement bars. The development of mixtures and their mechanical properties were also presented.The concrete mixtures were developed using the Taguchi optimization method. Three mixtures, labelled T4, T7, T10 and a control mix were investigated further. Mechanical properties such as compressive strength, tensile strength, flexural strength, Young’s Modulus of Elasticity were determined for each mix. In addition the water absorption/AVPV and drying shrinkage were also measured. The seawater resistance study comprises chloride ion penetration, change in strength, change in mass, change in Young’s Modulus of Elasticity, change in effective porosity and change in length. The corrosion performance of steel reinforcement bars in fly ash geopolymer concrete was determined by measuring the corrosion potential by half-cell potential, accelerated corrosion test by impressed voltage method and microbiologically influenced corrosion incorporating algae. The microstructure of the samples was also investigated using SEM and microscope.It can be summarized that the fly ash geopolymer concrete has an equivalent or higher strength than the OPC concrete. The seawater resistance revealed a high chloride ion penetration into the fly ash geopolymer concrete due to lack of a chloride binding ability and continuous hydration under aqueous medium. The geopolymer concrete had a higher strength and small expansion following exposure to wetting-drying cycles. There was a rapid depassivation of steel reinforcement bars in fly ash geopolymer concrete, although it has a smaller corrosion rate than the OPC concrete. This could delay the pressure in generating cracks in the concrete cover which is not favourable in the long term, due to a sudden loss of load carrying capacity. A novel study on the corrosion performance in algae medium demonstrated a risk of steel bar corrosion in fly ash geopolymer concrete due to the low alkalinity of this concrete. It can be concluded that the low calcium fly ash geopolymer offers some advantages in durability for reinforced concrete in seawater environments.

Abstract (sommario):

As climate change is progressing, it is important to find mitigation strategies to reach the Paris Agreement’s long-term temperature goal. The objective is to keep the increase in global average temperature to well below 2 °C above pre-industrial levels. One approach to climate change mitigation is to decrease people’s carbon footprint. This complex problem can be approached with top-down programs and bottom-up methods. One such a bottom-up approach is the app Deedster. This app is designed to educate its users about sustainable behavior choices and encourage the users to try out these new behaviors in so-called deeds to reduce their personal carbon footprint. In this research, an exploratory qualitative approach was taken to gather insights into the suitability of the Deedster app as a tool to change individual behavior towards a more sustainable lifestyle as well as investigating obstacles to acting sustainably. App users were interviewed in the beginning and at the end of a four-week Deedster challenge. The findings suggest that the Deedster app is a suitable tool to encourage behavior change and to educate its users about sustainability topics. Based on the results, the app may be stronger in changing low-cost (less difficult) behavior changes than effortful behavior changes. However, in some cases, also effortful behavior changes were reported. In addition, the users reported more knowledge about sustainable lifestyle alternatives and opened conversations about the app and their behavior changes with others. This study makes valuable contributions to the field of sustainable behavior changes and proposes the Deedster app as a useful method to engage more people in sustainable lifestyles.

Abstract (sommario):

AbstractTo mitigate the ongoing progress of climate change, the European Commission announced in the European Green Deal to reduce greenhouse gas emissions by 55% until 2030 compared to the reference year 1990 and to achieve climate neutrality by 2050 [1]. In this context, the industry in particular faces environmental challenges due to its high energy demand. To achieve the objective of becoming climate-neutral, increasing the energy and resource efficiency in the industry is crucial, because a large proportion of the greenhouse gases released are emitted during the provision of energy. In the automotive industry, paint shops are among the most energy-intensive processes and have great potentials for efficiency measures. These potentials can be identified with the assistance of energy or CO2 balancing methods. This publication presents a tool to analyse the energy efficiency potentials of automotive paint shops. The approach offers the possibility to parameterize different painting processes and their sub-processes. After defining the process requirements, a thermodynamic and process engineering simulation of the individual process steps enables the identification of potentials for energy and resource savings and CO2 reduction in existing or planned painting processes. In a validation on a real reference scenario, the simulated CO2 emissions of a paint shop were reduced by up to 24%.

Abstract (sommario):

The aim of the paper consists in the treatment of post-consumer and technological waste of elastomers and plastomers, according to the 4R principle (reduction, reuse, recycling and recovery) by transforming them into raw materials with added value and integrating them into different industries. This will lead to the developing of new processing concepts regarding obtaining new biodegradable composite materials, with various waste contents (10-50 wt%). The composite is based on chloroprene rubber, and added post-consumer recycled rubber particles, with size of 45 mesh, eco-reinforcing material, and active fillers, plasticizers, vulcanizing agents, antioxidants. In order to enhance the compatibility and their level of interaction, the elastomer waste was finely ground (cryogenic mill) and functionalized with potassium oleate. Rubber waste acts as a filling material which leads to lower carbon footprint of the composite and lower mass. Tensile, tear strength, elasticity, hardness, abrasion resistance, melt flow index and morphological study (FT-IR) of those composites were examined in order to determine their viability in various application areas. The transformation of waste (cryogenically ground, and functionalized) into new products with added value will lead to remarkable improvements in the life cycle of raw materials and the sustainable use of this waste, contributing to increasing sustainability, improving eco-efficiency and economic efficiency and reducing the carbon footprint on the environment.

Abstract (sommario):

Abstract The utilization of ordinary Portland cement (OPC) in well cementing is accompanied by technical and environmental problems, leading researchers to explore alternative materials that address these issues and promote eco-friendliness. Geopolymer technology, widely used in construction and other industries, has not yet been fully implemented in oil and gas well cementing. Industrial waste materials, such as Class F fly ash (FFA), can be utilized to improve cement properties or create new cement binders. Hematite is used as a weighting agent to increase cement slurry density. However, heavy particle sedimentation in cement and geopolymer slurries is a significant issue that leads to heterogenous properties along the cemented section. This study introduces a new class of geopolymers that use both hematite and Micromax as weighting materials for high-density well cementing applications. One system only used hematite, while the other used both hematite and Micromax in an effort to eliminate sedimentation issues associated with hematite in geopolymers. The effects of adding Micromax on different FFA geopolymer properties were also evaluated. The study evaluated mixability, rheology, and pumpability to determine the mix design, which was then used to examine other properties such as strength, and density variation. The results showed that adding Micromax to hematite reduced the average density variation from 12.5% to 3.9%. Micromax addition also decreased plastic viscosity by 44.5% and fluid loss by 10.5%. Both systems performed closely in terms of strength.

Abstract (sommario):

Energy transition discussions, policymakers are increasingly viewing hydrogen as a preferred emissions-free substitute for oil, natural gas and coal in hard-to-abate sectors. However, hydrogen is not a primary energy source but rather is a carrier of energy. Many factors, including its source and the technology used to manufacture it, influence its production costs. Currently, hydrogen manufacturing processes themselves have significant carbon footprints. Thus, for hydrogen to be accepted as a low-carbon fuel source, its production methods must also be decarbonized.
