Biodegradable mulch films are accused of creating harmful microplastics and leaching toxic additives into soil. The science is real — but the conclusions being drawn from it are often wrong. Here is a material-by-material breakdown of what the evidence actually shows, what should be restricted, and why bioplastic films are still better than polyethylene.

Deep dive into bioplastic additives: plasticizers, nucleating agents, impact modifiers, thermal stabilizers, UV stabilizers, processing aids, fillers, compatibilizers, chain extenders, and antimicrobial agents. Includes commercial product recommendations and chemistry explanations.
