Converting and Recycling of Waste Materials

Dear Colleagues,

This Topic brings together multidisciplinary research focused on transforming agricultural residues, biomass, and agro-industrial byproducts with value-added, carbon-based products. Innovations in thermal, biological, and chemical conversion technologies offer promising solutions to reduce waste, enhance soil health, generate renewable energy, and create sustainable chemicals, supporting circular bioeconomies and climate-smart practices.

We invite contributions that explore the development, optimization, and application of technologies such as biochar production, anaerobic digestion, pyrolysis, composting, and fermentation, particularly those that generate environmental, economic, and social co-benefits in the context of sustainable agriculture, food security, and resource recovery. These technologies have the potential to improve plant health, reduce disease pressures, support equitable food systems, and enhance STEM education through real-world applications and community engagement. We especially welcome interdisciplinary work that connects technical innovation with inclusive pedagogical strategies and equity-centered practices, fostering collaboration among researchers, educators, and practitioners across engineering, agricultural sciences, environmental sciences, and social sciences.

By bridging technical innovation with inclusive practices, this Topic seeks to advance knowledge and real-world impact in waste valorization, agroecology, and sustainability education.
