Rapid population growth and urbanisation have accelerated waste generation, and effective waste management has become a major challenge worldwide. With advances in technology and management methods, waste management strategies have begun embracing digitalisation, leveraging the Internet of Things (IoT), big data analytics, cloud/edge computing, machine learning, 5G communication, and blockchain technologies. Amongst them, the blockchain technology has the structural features of achieving information security and integrity without central guarantees. Blockchain also meets the data record/storage needs of waste management and the design of new mechanisms for effective waste management. These benefits make blockchain an attractive technology in the field of waste management, with researchers and practitioners alike investigating its broad applications to support sustainable waste management. However, this emerging technology has not yet been widely accepted by potential users. To further champion the application of blockchain technology, this review paper provides a systematic overview of the various pathways in which the technology has been applied in the waste management industry and further discusses its related challenges and opportunities via considering the promising prospect of combining blockchain technology with IoT, artificial intelligence (AI) and life cycle assessment (LCA). This review also provides insights for interpreting some emerging applications of blockchain in the field of waste management and clarifying the research paths in the context of blockchain, digitalised waste management, and circular economy. [Display omitted] • Impacts of blockchain technology on waste management have been substantial. • Recent development from blockchain's functional perspectives was surveyed. • There is a long way towards blockchain-based sustainable waste management. • Relevant challenges and opportunities in blockchain applications were discussed. • Outlooks in digitalised waste management and circular economy were clarified.

Abstract Combining sustainable consumption with the circular economy concept could help tackle challenges, such as resource scarcity and climate change by reducing resource throughput and increasing cycling of products and materials within the economic system, thereby reducing emissions and virgin material use. To achieve sustainable consumption in a circular economy production and consumption practices need to change. Business models can potentially influence both practices as it defines how a company conducts business and shapes the company-consumer relationship. This paper developed future business models for sustainable consumption through two rounds of semi-structured interviews with experts from academia, industry, and policy. During the first interview round, four business model elements that are important for sustainable consumption were identified: Resource strategy, Revenue model, Consumer effort, and Objective to (decrease/increase) consumption level. Based on these elements, we developed a comprehensive business model framework. Using this framework, experts envisioned future business models for sustainable consumption of clothing during the second interview round. The findings of this study suggest that the most promising business models for sustainable consumption are those that reduce overall consumption levels and consumer effort. Further, we found that a diverse range of business models in the market can potentially enable different customer segments to consume sustainably. [ABSTRACT FROM AUTHOR]

The growing importance of the concept of the circular economy as a way to attain sustainable development has encouraged scholars to propose different ways to understand it. Given the large number of studies done on the circular economy, their differing approaches and their multiple applications, this paper attempts to propose a consensus view of the basic notions of the circular economy framework and highlight its relationship with eco-innovation. To that end, this study carried out a systematic literature review that resulted in four main outputs: a knowledge map of the circular economy, an analysis of the main notions of the concept, principles, and determinants of a circular economy. Finally, this study brings to light some remarkable examples of eco-innovations developed for implementation in the circular economy. [ABSTRACT FROM AUTHOR]

Soil amendment is a viable alternative to chemical fumigants thanks its benefits on soil quality, microbial biodiversity, and plant health being valorized underused biomass. Nonetheless, the concepts of durability and stability for disease suppressive soils are became a critical issue in the advanced organic cropping systems. Although a comprehensive and critical literature is available, this paper briefly analyzes the governance of the soil organic amendments as an external source of organic matter and beneficial microbiota in view of new opportunities and technological advancements. Particularly, it discusses some possible solutions for developing the suppressive properties of the amended-soils by helping grower to well understand the complex processes/interactions that lead to soil suppressiveness from the most practical viewpoints according to the principles of green economy.
