Special Issue Information

Dear Colleagues,

The constant increase in the global population has led to a rise in food waste generation across the industrial, agricultural, and household sectors. Despite being rich in bioactive compounds such as polysaccharides, proteins, carotenoids, and phenolics, only a quarter of this waste is repurposed as animal feed, while the majority is discarded. Beyond the issue of food loss, these practices have significant environmental, economic, and social consequences, depleting essential resources such as water, land, and energy.

This Special Issue will enhance our understanding of effective agricultural by-product management, aiming to reduce the environmental impact of waste accumulation and develop value-added materials for integration into new industries and processes. Submissions should be aligned with the principles of green chemistry by incorporating agricultural waste valorization, environmental sustainability, and circular economy approaches. Studies examining the effects of management strategies and socioeconomic factors on the sustainability of agricultural waste systems are also encouraged. Both original research articles and review papers are welcome.

This study evaluates the application of circular economy principles in the wine sector through a demonstrative case developed within the LIFE Climawin project. The initiative focuses on the local valorization of vineyard residues by producing biochar from vine pruning and using it to enrich compost derived from winemaking by-products and sheep manure. The combined application of these soil amendments aims to improve soil structure, enhance carbon sequestration, and reduce reliance on synthetic fertilizers. A systemic evaluation was conducted using the Ecocanvas methodology—a conceptual framework for mapping circular business models across environmental, economic, and social dimensions. The analysis integrated a targeted literature review, examination of technical data, direct field observations of composting and biochar production, and semi-structured interviews with key stakeholders. Results indicate multiple benefits from localized residue valorization, including improved compost quality, reduced greenhouse gas emissions, potential contributions to long-term soil health, and enhanced resource efficiency. The analysis also highlights economic opportunities, such as reduced dependency on external inputs, and social value creation through local stakeholder engagement. Furthermore, the study identifies factors that enable or constrain the replication and scaling of this model. These findings contribute to frameworks for advancing circular, economically viable, and socially inclusive climate-resilient agricultural systems. Full article
