ClearExtruded Porous Protein–Lignocellulosic Blendsas Fully Bio-Based Alternative to Single-Use Absorbent Plastics
Researchers developed fully bio-based porous absorbent materials by extruding blends of proteins and lignocellulosic residues — including oat husk, wheat bran, and keratin fibres — sourced entirely from biomass waste, as sustainable alternatives to single-use synthetic absorbent plastics. Saline absorption capacity increased 1.5 times with oat husk inclusion and doubled after a delignification step, demonstrating the potential of biomass-derived extrusion for competitive eco-friendly absorbents.
Porous Thermoformed Protein Bioblends as Degradable Absorbent Alternatives in Sanitary Materials
This study demonstrates that biodegradable protein-based foams made from industrial byproduct proteins (zein and gluten) can be processed into absorbent pads and films that perform like conventional disposable sanitary products — without the plastic components that shed microplastics. By replacing nonbiodegradable polymer layers in diapers and pads with compostable biopolymers, this approach could cut a major but underappreciated source of microplastic pollution.

Scientists developed biodegradable porous absorbent materials made from agricultural protein waste and a natural plant-based crosslinker, as an alternative to fossil-fuel-derived absorbents.
