How to break down plastic?
Until other researchers can replicate Burd's experiment and waste treatment plants can implement any new processes, the only real way to break down plastic is through photodegradation. This kind of decomposition requires sunlight, not bacteria. When UV rays strike plastic, they break the bonds holding the long molecular chain together. Over time, this can turn a big piece of plastic into lots of little pieces.
Is plastic a decomposer?
Plastic isn't a material that decomposes, but must be recycled. Instead, plastic tends to break down into smaller particles until they are too small to be seen. This means that every molecule of plastic produced since 1907 is still present in the environment. .

Based on this logic, it's safe to argue that plastic will never biodegrade. Of course, that's not the end of the story.
What happens to polypropylene after insertion?
The study concisely summarizes the degradation process of polypropylene, “Immediately upon insertion an acute inflammatory reaction begins. Neutrophils are the first cells to arrive. They begin to produce oxidants, including hydrogen peroxide and hypochlorous acid, which continue the heat induced oxidative process begun during manufacture. In the environment of the human body polymers undergo varying degrees of degradation. Oxidation of the PP chains produces free radicals, which cause various events, including depolymerization (breakdown of the molecular chain), cross-linking, oxidative degradation, additive leaching (which may include toxic substances), hydrolysis and stress cracking. This process produces more free radicals, which perpetuate the chain reaction. Enzyme catalysts allow these reactions to occur at body temperature. Ultimately due to the breakdown of the structural integrity of the PP polymer chains the mesh shows signs of surface alterations initially and then deep cracking of the fibers. The end result is lessened structural integrity with changes in molecular weight and crystallinity. The mechanical integrity of the implanted mesh is also decreased.”
Why was the 30 polypropylene hernia mesh removed?
The 30 polypropylene hernia mesh explants were removed because of pain, discomfort, and/or hernia recurrence that may cause the mesh to be a potential source of further complications.

What is a biodegradable plastic made of?
Plastics treated with organic additives promote biodegradation in landfills by allowing the already present bacteria and fungus to dissolve the plastic , layer by layer.
Does EnvyPak’s’ BioPoly start to break down while it’s still in use?
No. For biodegradation to occur, EnvyPak biopoly must be disposed of properly in a landfill. Light, oxygen, moisture, and heat all help the process along. As the bioplastic comes into contact with certain landfill microbes, the microbes send out signals (described as a “quorum-sensing process”) that attract other microbes. This, in turn, hastens the breakdown of the chemical bonds of plastic polymer.
