Conversion strategies for durian agroindustry waste: value-added products and emerging opportunities

March 22, 2024 | Journal of Material Cycles and Waste Management |

Conducted by Ho Chi Minh City University of Technology (HCMUT), Vietnam, this study addresses the substantial challenges posed by durian (Durio zibethinus) waste, which constitutes 65–80% of the fruit and presents significant waste management issues. The paper provides an overview of potential methods for durian biomass treatment, focusing on four main approaches: thermochemical treatment for energy generation, physicochemical pretreatment for fiber extraction, microbiological conversion techniques, and green solvent extraction of polysaccharides and phytochemicals.

The study highlights the persistent challenges associated with the recalcitrant structures and high volatile matter contents of durian waste, discussing notable problems and proposing solutions for each treatment method. Emphasis is placed on the potential value-added products that can be derived from these methods, each offering different functional properties. Additionally, the study considers scalability and offers recommendations for optimizing the processing of durian waste economically, including suggestions for combining different technologies or biomass sources. Overall, the findings contribute valuable insights into sustainable approaches for durian waste management and valorization.
