ClearDevelopment of bio-composite mulch film from cotton gin wastes: Study of pesticide residue and outdoor stability and degradation
Researchers developed biodegradable mulch films made from cotton gin waste — an agricultural byproduct — combined with polycaprolactone, and showed they can remain stable during a growing season while degrading more readily than conventional plastic films. Replacing non-degradable plastic mulch, which fragments into soil microplastics, with truly biodegradable alternatives is an important step toward reducing agricultural plastic pollution.
