In a step towards a sustainable world, Dr Debajyoti Kundu, Assistant Professor, Department of Environmental Science and Engineering, has published a paper titled “Systematic Valorisation and Circular Bioeconomy Prospects From Potato Wastes: A Review” in the Q1 journal Bioresource Technology Report having an impact factor of 4.3. His research explores how discarded potato by-products like peels and pulp can be transformed into useful products such as biofuels, fertilizers, and even pharmaceuticals. The study emphasises how turning waste into resources can help create a cleaner, more sustainable world while boosting the economy.

Abstract
Potato processing industries generate vast amounts of waste such as peels, mash, pulp, and process water, which are often discarded without value recovery. These residues, rich in carbohydrates, proteins, and bioactive compounds, can serve as promising feedstocks for biorefineries. This review presents a systematic analysis of recent advances in valorizing potato wastes into biofuels, chemicals, enzymes, and other value-added products. It highlights their potential to enhance resource efficiency, reduce environmental impact, and support circular bioeconomy principles aligned with multiple UN Sustainable Development Goals (SDGs).

Practical Implementation / Social Implications of the Research

The valorization of potato waste can significantly reduce landfill loads, lower greenhouse gas emissions, and contribute to clean energy generation. Implementing biorefinery-based approaches promotes sustainable industry practices, supports rural economies, and aligns with the global transition to a circular bioeconomy.

Dr Kundu stated that future investigations will focus on developing scalable biorefinery models, optimizing integrated processing routes, and exploring industrial symbiosis approaches for complete resource recovery from agri-food wastes.
