Acylation of agricultural protein biomass yields biodegradable superabsorbent plastics

A. J. Capezza, F. Muneer, et al.

Discover how researchers, including Antonio J. Capezza and Faraz Muneer, are pioneering sustainable, biodegradable superabsorbent polymers from agricultural potato protein. This innovative approach not only enhances water swelling capacity but also reduces CO2 emissions, setting the stage for eco-friendly hygiene and medical products.

Abstract
Superabsorbent polymers (SAP) are crucial in hygiene and medical products, but are usually petroleum-derived. This study demonstrates sustainable, biodegradable SAP production by acylating agricultural potato protein side-stream (PPC) with a non-toxic dianhydride (EDTAD). The treated PPC exhibits a water swelling capacity of approximately 2400%, ten times greater than untreated PPC. Acylation on waste potato fruit juice (PFJ) before industrial PPC precipitation is also explored, offering significant CO2 emission reduction. The acylated PPC shows biodegradability and mold resistance, promising environmentally friendly disposable products.
