How can low-value agricultural waste be transformed into high-value products?

Phys · · 969 words · By Addison DeHaven
Agricultural Innovation Environmental Sustainability Circular Economy

Associate professor Srinivas Janaswamy of South Dakota State University discusses his research on creating biodegradable packaging films from agricultural waste, including coffee grounds, soybean hulls, and cow dung. The work aims to provide a sustainable alternative to single-use petroleum-based plastics by utilizing cellulose extracted from biomass.
