The preferences and adoption of recycled materials by consumers are subject to a variety of factors, such as enablers and barriers. Despite this, there exists a paucity of research concerning stakeholders' perceived value and real purchase decision towards recycled products. Consequently, this research study aims to fill this gap by investigating stakeholders' perceived value of recycled products derived from construction and demolition (C&D) waste and its effect on purchase decisions.

Research data were collected from 219 valid questionnaires completed by Chinese stakeholders. Structural equation modeling (SEM) was then employed to test eight hypotheses.

The results show intrinsic cue (materials) and extrinsic cue (brand) influence the stakeholders’ judgment on C&D waste recycled products’ value and then their purchase intention. However, cues such as quality, word-of-mouth, price, policy and advertised have not play a significant role in practice.

This research study verified the significance of brand and material cues on decision making for purchasing C&D waste recycled products, providing new insights to policy making to enhance the uptake of C&D waste recycled products in construction industry.

Regarding the retail internal supply chain (SC), both retailers and research are currently focused on reactive food waste reduction options in stores (e.g. discounting or donations). These options reduce waste after a surplus has emerged but do not prevent an emerging surplus in the first place. This paper aims to reveal how retailers can proactively prevent waste along the SC and why the options identified are impactful but, at the same time, often complex to implement.

The authors follow an exploratory approach for a nascent topic to obtain insights into measures taken in practice. Interviews with experts from retail build the main data source.

The authors identify and analyze 21 inbound, warehousing, distribution and store-related options applied in grocery retail. Despite the expected high overall impact on waste, prevention measures in inbound logistics and distribution and warehousing have not been intensively applied to date.

The authors provide a structured approach to mitigate waste within retailers' operations and categorize the types of barriers that need to be addressed.

This research provides a better understanding of prevention options in retail operations, which has not yet been empirically explored. Furthermore, this study conceptualizes prevention and reduction options and reveals implementation patterns.

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Managing farm waste is a fundamental problem for farmers with economic, environmental and social impacts throughout the supply chain. Little research has explored innovative product solutions. This paper examines gleaning to reduce farm waste and proposes a resource-based Gleaning Innovation Framework which can lead to differentiated consumer products.

A multi-method approach, including descriptive company reviews, practitioner interviews and consumer surveys, evaluated how different participants in the food supply chain view the farm waste problem and the innovation of products through gleaning.

This research found that practitioners and consumers are cognizant and invested in reducing farm waste, with gleaning as a plausible solution. Future research includes gathering perspectives from retailers and other supply chain members, which may further develop the conceptualization of the gleaning innovation process.

Uniquely, the authors propose the Gleaning Innovation Framework that provides a platform for innovation across the supply chain to reduce farm waste. The research contributes to the farm waste debate with evidence that gleaning can assist the reduction of farm waste through product innovation. Developing innovations to reduce farm waste in sustainable and environmentally friendly ways would not only benefit the supply chain platform but also society.

The need for innovations to achieve economically viable and green supply chains has been illuminated in recent literature. Closed‐loop supply chains are part of green supply chain management and include traditional forward supply‐chain activities as well as additional activities of the reverse supply chain. Extant supply chain literature calls for a chain perspective in order to avoid sub‐optimization in the chain since changes at one stage can affect the performance at other stages. The purpose of the paper is to analyze how implementation of green supply chain innovations can enhance value offerings along the supply chain.

This research is based on an explorative, single‐embedded case study of a food supply chain. The case is concerned with implementation of green supply chain innovation in terms of biogas technology. The single case comprises four actors in the food supply chain: a retailer, an industrial bakery, a mill, and a farmer. Data collection is based on semi‐structured interviews with persons responsible for sustainability in the respective companies.

The case demonstrates that in order to reach the full potential of a green supply chain innovation, the different supply chain actors must be included. What in isolation of one company's perspective is perceived as a waste can be transformed to a value when the problem area is analysed from a chain perspective.

The paper is based on a single case study that does not provide static generalizations, and it represents the first step on a road to building new theory about green supply chain innovations. Future research can expand the findings by elaborating upon cases of other types of supply chains and supply chain innovations.

The perception of waste in a supply chain can be changed through green supply chain innovations. This case illustrates how obsolete food products at the retail level, which traditionally have been perceived as a waste product with related discarding costs, can be regarded as a valued input by implementation of biogas technology at the industrial bakery company. As a result, other food supply chains can investigate similar solutions.

The paper provides a case that visualizes how value offerings along a food supply chain can be chased through green supply chain innovations. Furthermore, the paper applies a supply chain perspective not only conceptually but also empirically. By focusing on the interfaces between each main actor in the supply chain, this paper contributes to existing research with valuable knowledge of inter‐organizational issues related to challenges of supply chain innovation.

This purpose of this paper is to understand the environmental impacts of stakeholder-driven sustainable purchasing policies in institutional settings.

The research is framed using stakeholder and life cycle assessment (LCA) theories. The study uses a multi-method approach. Starting with interviews to understand the breadth of sustainability issues and significant food purchases facing institutional purchasing managers, the authors subsequently perform LCA of these various policies using the most popular food item in different categories.

From the interview results, the authors found that food purchasers focus predominately on cost, thus, are committed to food and packaging reduction. They are driven to buy local foods based on their consumer stakeholders but share their commitment to buying local products if the cost is appropriate. In the LCA of popular food items in multiple scenarios, avoiding food waste of various forms had significantly higher carbon emissions savings than packaging reduction or transportation minimizing (buy local) strategies.

The sample relied solely on the perceptions of institutional purchasing managers in university dining services. Future research should involve collecting data from other stakeholder groups such as the customers themselves, institutional leaders, and in other types of institutional settings such as hospitals and government agencies.

The research provides managers with insights concerning the trade-offs between different sustainability objectives. In particular, findings show that reducing waste related animal protein has a bigger impact on environmental performance than many other popular sustainability objectives such as buying local or reducing packaging waste.

The paper focuses on the purchasing trade-offs of buying local vs national food products, different packaging solutions, and food waste generation. These decisions offer some social benefits (improve the economic situation for local farms vs consolidated food producers) as well as multiple environmental benefits.

The paper presents new findings on the sustainability purchasing priorities of stakeholders in institutional food settings and subsequent LCA of those policies to show which might have the most environmental impact.

Creating systems designs by considering a balance between economic, environmental, and social effects is significant in today's sustainability concern. Sustainability has become an emerging topic, growing concerns and attention for companies. Especially companies operating on a global scale aim to develop strategies for sustainable supply chain management. When the supply chain is a food chain, that concern increases exponentially and sustainable management of the chain becomes a critical challenge requiring the development and implementation of innovative practices by all stages within value chains. According to the Food and Agriculture Organization (FAO), a significant amount of food is wasted or lost in the journey from farm to fork. This waste affects the global economy, food availability, as well as the environment negatively. In this work, we, therefore, focus on addressing these aspects by searching how food waste or food loss could be reduced throughout a supply chain network. We provide solution ways for the food waste/loss reduction obtained from current works in literature.

The rapid technological growth, changes in consumer demands, products’ built-in obsolescence, presence of more non-repairable parts, shorter lifespan, etc., lead to the generation of e-waste at an unprecedented rate. Although a number of research proposals and business products to manage e-waste exist in the literature, they lack in many aspects such as incomplete coverage of product’s life cycle, access control, payment channels (in few cases), incentive mechanisms, scalability issues, and missing experimental validation. The purpose of this paper is to introduce a novel blockchain-based e-waste management system aiming to mitigate the above-mentioned downsides and limitations of the existing proposals.

This paper proposes a robust and reliable e-waste management system by leveraging the power of blockchain technology, which captures the complete life cycle of e-products commencing from their manufacturing as new products to their disposal as e-waste and their recycling back into raw materials.

While the use of blockchain technology increases accountability, transparency and trust in the system, the proposal overcomes various challenges and limitations of the existing systems by providing seamless interactions among various agencies.

This paper presents a prototype implementation of the system as a proof-of-concept using solidity on the Ethereum platform and this paper performs experimental evaluations to demonstrate its feasibility and effective performance in terms of execution gas cost and transaction throughput.

The purpose of this paper is to expand understandings of how logistics can reduce food waste in food supply chains (FSCs).

Using a research framework that associates causes of food waste with logistics solutions, a multiple-case study was conducted in three Swedish FSCs of meat, fruit and vegetables, and ambient products, respectively, and involving industrial producers, wholesalers, and retailers. Data were collected during 19 semistructured interviews and four site visits, and logistics solutions were analysed according to logistics activities, actors involved and their stages in the FSC, and coordination mechanisms.

A joint analysis of nine logistics solutions revealed that to efficiently reduce food waste in FSCs, solutions have been implemented at three stages of FSCs, as well as that those solutions differ in their integration of six logistics activities and four coordination mechanisms. The findings moreover indicate that the solutions are interlinked, thereby implying that coordination is necessary both within solutions as well as among them.

The chief limitation is that the potential of the identified logistics solutions is not quantified.

The paper makes recommendations for reducing food waste in FSCs by developing new solutions and modifying existing ones.

The paper suggests ways to reduce significant environmental impacts of food waste.

By building upon previous research explaining causes of food waste, this paper focusses on logistics solutions for reducing such waste.

This work aims to assess the potential of a Bio-District as a model for applying the circular economy concerning the waste scope. It aims to understand the capability of organic farms to manage waste with a circular perspective, starting with the use of indicators that directly or indirectly impact the waste scope.

This study is based on previous work that identified and systematised the circular indicators of the agri-food sector within a dashboard. With this research as a basis, the indicators within the waste scope in the dashboard were extracted. Cross-linked indicators with an indirect connection to the waste scope were also systematised and tested in a case study. Primary and secondary data were used for the study. The primary data came from a semi-structured interview, and the secondary data were from official databases.

The work highlights two important results. The first allows the definition of a subclassification of indicators by product and organisation, extracting those with a cross-linked characteristic concerning the waste scope. Secondly, the indicators' application shows the farm's circular and waste valorisation potential within the Bio-District. The study also made it possible to test a new indicator, the “Potential Energy Biomass Recovery”, to measure the farm's potential to produce energy from waste.

This research proposes a new circular economy approach to evaluate waste management in the agri-food sector.
