This presentation will highlight how insect farming byproducts can be transformed into valuable materials for environmental and industrial applications. A major focus will be on the use of insect frass and insect-derived chitosan as sustainable feedstocks for water purification technologies. Chitosan is a versatile biopolymer that can adsorb contaminants and can also be chemically modified to selectively capture metals, dyes, nutrients, and emerging pollutants such as PFAS. The talk will discuss strategies for functionalizing chitosan to improve adsorption capacity, selectivity, processability, and regeneration. Additional examples will include chitosan nanoparticles and hybrid materials for delivery systems, antimicrobial coatings, and responsive materials. The presentation will also examine how insect agriculture can support circular economy models by converting low-value waste streams into high-value specialty materials. Opportunities for collaboration between insect producers, engineers, and materials scientists will be emphasized. Overall, the talk will demonstrate how chemistry can expand the value chain of insect farming beyond food and feed production.
