Valorization of peanut shells has recently gained prominence in the context of thermally converting agricultural waste into biochar, a carbon-rich byproduct with significant potential as a soil amendment. The present study delves into understanding the influence of slow (450°C and 500°C) and fast (550°C and 600°C) pyrolysis temperatures with a resident time of 60 and 30 minutes, respectively, on the physico-chemical properties of peanut shell biochar produced in a low-cost kiln. Results of the Scanning Electron Microscopy analysis revealed that increased pyrolysis temperature increased porosity and surface roughness with crystalline deposits. Thermogravimetric analysis showed that increased temperatures contributed to enhanced thermal stability but reduced biochar yield. Pyrolysis temperatures of 450, 500, 550, and 600°C exhibited 32.19, 29.13, 21.8, and 19.43 percent conversion efficiency with organic carbon content of 11.57, 6.48, 8.64, and 7.76 percent, respectively. The intensities of functional groups (C-H and C-O) declined, whereas the intensity of C=C and stable carbon content increased with the rise in temperatures. The concentrations of heavy metals in all biochar samples were below permissible limits outlined by international biochar initiatives. The study concluded that slow pyrolysis at 450°C for 60 minutes resident time is an ideal pyrolytic condition for producing peanut shell biochar in terms of qualitative and quantitative characteristics.

The construction industry in Jordan plays a pivotal role in the national economy but also generates a significant amount of concrete waste, leading to environmental and health challenges. Current waste management practices involve landfill use and unregulated disposal, demonstrating the country's infrastructural shortcomings in concrete waste handling. Despite the recognized importance of the construction sector and the challenges of concrete waste management, more comprehensive studies need to focus on the practicality and benefits of recycling concrete within a circular economy framework in Jordan. This gap hinders the development of effective strategies that could mitigate environmental impacts, promote sustainability, and leverage economic and social benefits in the construction industry. Given the accelerating urbanization, increasing environmental awareness, and the pressing need for sustainable development goals, the timing for this study is critical. It aims to catalyze a timely shift toward more sustainable waste management practices that align with global sustainability trends and national priorities. This study aims to fill the knowledge gap regarding the practicality of recycling concrete within a circular economy context in Jordan and explore the hypothesis that adopting circular economy principles can enhance resource efficiency, reduce waste, lower greenhouse gas emissions, foster economic benefits, and create job opportunities within the sector. Methodologically, this research comprises an analysis based on literature, international comparisons, and technical, economic, and ecological explorations of concrete recycling in Jordan. The literature study establishes a foundational understanding of the current waste management landscape, the anticipated benefits of concrete recycling, and the challenges to its implementation. Furthermore, a technical analysis evaluates the quality and applicability of recycled concrete. The in-depth examination of Jordan's concrete waste problem highlights the urbanization challenges, regulatory gaps, and environmental, social, and economic impacts. Barriers, solutions, and recommendations are discussed through an interdisciplinary lens. This integrated approach supports the transition toward a sustainable, environmentally responsible, and economically viable construction sector. The findings could contribute to policy-making and the advancement of industry practices, ultimately promoting sustainable development in Jordan.

The global turkey market represents a sector of increasing growth in the previous decade, and projections for the next decade reflect the probable continuation of this growth. Industry trends also indicate the globalization of turkey meat production, as the loci of production has continually shifted from one dominated by the United States to one with an increasing number of production units globally. In contrast with other popular meat products, comparatively fewer resources have been devoted to academic research concerning the growth, production, distribution, and sale of turkey and turkey products. This lack of research is particularly notable in the area of supply chain management and environmental sustainability. Given the increasing volume of turkey production and lower volume of academic interest, it stands to reason that there remain many opportunities for improvement across the value chain in this industry.In this paper, we take a “green logistics” approach and use data provided by one of the largest turkey producers in the United States to formulate a mixed-integer program aimed at minimizing the environmental impact of turkey products in a segment of the product supply chain.Implementation of the resulting brooder-finisher farm assignments developed by the model would yield an average 50% decrease (184 metric ton) in greenhouse gas emissions at the operation under investigation while also addressing other areas of significant vulnerability for the industry (production costs, biosecurity risk, and animal wellbeing).As consolidated turkey meat production systems continue to expand globally, we argue that a similar approach could readily be deployed by these growing and emerging production systems.

After several decades of work toward elevating sustainability education, many have called for a transformation of the education system to create timely action. Teachers, students, organizational leaders, and many other stakeholders have voiced their dissatisfaction with their experience of sustainability education. Some say we can do more to create real action for sustainable futures. We investigate what, how and why lectures across disciplines at universities in different countries work with sustainability education. We conduct interviews and dialogs with teachers across disciplines to uncover interdisciplinary perspectives on sustainability education and how to move forward. The emerging reflections provide insights about transformations in the strategies and systems, and how to implement sustainability education. There is also a call for reuniting diverse intrapersonal and values thinking between stakeholders to support transformations in sustainability education. Furthermore, participants imagined the future as a creative space where collaboration across disciplines facilitates a student-centred transdisciplinary experience with real-world practice. This study provides insights into the mindset of teachers across disciplines and countries. A sustainability competence-based support model about the current sustainability education discourse is developed.

Agent-based modeling and simulation is a method well suited for studying individual behavior and interactions among members of a population connected by social networks. Although the development of such simulation models can be relatively complex, it is even more challenging to develop models that are empirically valid. In the case of reverse logistics, the sophisticated and difficult-to-predict behavior of consumers must be modeled. In this paper, an agent-based simulation model of consumer behavior and interactions was configured to conduct a case study of the voluntary deposit collection program for wine bottles in the Val-Saint-François region of Quebec. As this collection program was officially launched in 2019, two empirical samples were obtained to test the validity of the model and study how social interactions such as word of mouth contributes to the success of the collection program. The first sample represents the amount of glass collected during the last 26 weeks of 2019, while the second sample covers the first 13 weeks of 2020. Having observed an increase in collection rates between 2019 and 2020, word of mouth was introduced into the model to explain this phenomenon. Statistical tests show that the model is indeed valid with the inclusion of diffusion of awareness, as the simulation results are significantly consistent with the empirical data. The validation of the model demonstrates the viability of using multiple heterogeneous data-sources to configure a simulation model based on the Theory of Planned Behavior without using Structural Equation Modeling.

Bulk mineral waste materials such as construction and demolition waste are Germany’s largest waste stream. Despite the availability of high-quality recycling pathways such as road base layers, waste concrete is predominantly recycled into lower-quality recycling pathways like earthworks or unbound road construction. This is due to low demand for recycled aggregates in road base layers and frost protection layers, especially in public procurement.This study assesses the environmental consequences of increasing high-quality recycling of waste concrete in the near future to provide decision support for public procurement in Germany. The focus lies on climate change due to its importance for decision-makers. However, 17 other impact categories were assessed to avoid problem shifting.Life cycle assessment (LCA) is applied with background data from ecoinvent 3.9.1. Impact assessment was conducted at midpoint level using IPCC 2021 and ReCiPe Midpoint (H). Foreground data were taken from literature and expert interviews. In line with the goal of this LCA, a consequential modeling approach was followed to account for changes in the material flow system. Substitution creates a cascade effect previously omitted in consequential LCA studies, in which lower quality recycling materials replace higher quality recycling materials in their respective utilization pathways.Increasing the high-quality recycling of waste concrete into road base layers causes a reduction in environmental impacts for all 18 impact categories, as it replaces natural aggregate and avoids backfilling of mixed mineral waste and excavated earth through substitution effects. Transport distances and ferrous metal recovery were identified as hot spots. Sensitivity analyses show that only transport is a significant issue.Increasing the high-quality recycling of waste concrete in Germany is recommended in terms of environmental impacts. Lower-quality recycling is environmentally feasible only in cases where the avoided transport distances for natural aggregates and backfilling are significantly lower than the additional transport distances for high-quality recycling.

The dominance of biomass for cooking has implications for the country. For instance, biomass conversion using traditional technologies (three stone) in poorly ventilated kitchens produce smoke that influences the reproductive health outcomes for expectant mother. Beyond health outcomes, uncontrollable harvesting of biomass for cooking contributes to environmental degradation. Unfortunately, biomass in form of firewood, charcoal, plant and animal wastes is widely consumed by more than 94% of Ugandan households for cooking. This paper examined whether perceived satisfaction plays a significant role in household energy transition in Uganda.The study adopted a panel data methodology employing an ordered logit model with random effects to estimate the effect of perceived satisfaction on household fuel transition from high to low pollutant cooking fuels in Uganda. The data used was obtained from Uganda Bureau of Statistics (UBoS) which is mandated by an Act of parliament to develop and maintain a national statistics system to ensure collection, analysis and publication of integrated, relevant, reliable and timely statistical information.Our findings demonstrate that perceived satisfaction influences household fuel transition decisions in Uganda. The study concluded by suggesting policy recommendations for government action.

The bioeconomy seeks to efficiently transform biomaterials into value-added products to achieve circularity. A circular bioeconomy is a circular carbon economy based on bio-based resources. There is a dearth of information in the literature about how psychological factors affect public acceptance of the bioeconomy, especially in Africa, where the adoption of bioeconomy is scant. Addressing this gap, this study characterized bioeconomy as a low-carbon bio-based technological innovation to combat climate change and developed the Bioeconomy Technology Acceptance Model (BTAM) to explain the effects of individual-level factors on public acceptance of bioeconomy and investigated it in a survey (N = 465) using questionnaires that were carried out in Lagos, Nigeria, in 2022. The respondents were chosen by proportional stratified random sampling, and descriptive statistics, Pearson’s correlation coefficient, and structural equation modeling were used to analyze the data obtained. The strong influence of perceived usefulness from bioeconomy and intention to accept bioeconomy in BTAM suggests that the Technology Acceptance Model (TAM) is suitable for predicting public acceptance of bioeconomy. Considering the strong influence of belief about climate change on the perceived usefulness of bioeconomy and intention to accept it in this study, it is imperative to promote climate change education among Africans to accelerate acceptance of bioeconomy on the continent. The identified psychological factors provide a reference for scholars, policymakers, and manufacturers to effectively develop individual-oriented intervention strategies and promotion schemes to enhance acceptance of bioeconomy in Africa in particular and other climes where there is not yet widespread acceptance of circular bioeconomy.

The identified psychological factors provide a reference for scholars, policymakers, and manufacturers to effectively develop individual-oriented intervention strategies and promotion schemes to enhance acceptance of bioeconomy in Africa in particular and other climes where there is not yet widespread acceptance of circular bioeconomy.","PeriodicalId":507840,"journal":{"name":"Frontiers in Sustainability","volume":"90 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139164010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demonstrated urgency of the climate crisis would require mobilization by a larger and more diverse set of participants than those usually recognized as environmental activists. Hence this article asks: (1) What conditions enable unlikely participants (such as men working in manual occupations) to engage in and identify with a climate movement? And (2) what is it about the relationship between participants’ biographies, the practices of the climate movement and the interaction between them that allows – or affords – such identification to occur? I draw on an approach to identity formation as situated practice, i.e., as occurring in situations where social relations are enacted while drawing on the individual experience and shared understandings that participants bring to the situation. Based on fieldwork in Finnish municipalities that have committed to climate neutrality, I find that the conditions for engagement depend on socio-cultural affordances for engaging in climate action, which (1) accept and welcome participants’ life histories and lifestyles (2) build on and respect participants’ competences and multiple forms of expertise, (3) engage participants in practices that are familiar enough not to produce anxiety but stimulating enough to be fun, and (4) produce small but visible achievements that are acknowledged as such by both participants and onlookers. The current study contributes to previous research arguing for a more populist approach to climate policy by emphasizing existing competences and embodied practices as an avenue for engagement in climate action.
