Bioremediation
Plastic waste in soils and waterways directly harms plant root systems, disrupts soil microbiomes that feed your garden, and contaminates the food you grow — better plastic breakdown means healthier ground for everything that grows.
Researchers reviewed how scientists are tweaking natural enzymes — biological tools that act like tiny scissors — to cut apart different types of plastic so they can be recycled or safely broken down. They looked at plastics found everywhere from drink bottles to packaging foam. The goal is to make these enzyme tools strong and fast enough to work in real-world recycling facilities.
Key Findings
Protein engineering has been applied to improve enzymes that degrade at least four major plastic types: PET, polyurethane, polylactic acid, and PBAT.
Key improvements targeted through engineering include thermal stability, catalytic efficiency, and the ability to produce these enzymes at industrial scale via recombinant expression.
The review identifies future directions needed to make enzymatic plastic depolymerization industrially viable, signaling the field is still maturing toward large-scale application.
