A special strain of soil bacterium Pseudomonas putida converts polystyrene foam into a biodegradable plastic called PHA, which can be used in medicine and disposable items. The process might also be used to convert other types of discarded plastics into PHA, reducing plastic waste.
Researchers have developed fully biodegradable composites made from soybean protein and plant-based fibers, which could replace plastic parts in various applications. These green composites provide excellent insulation and are low in cost, biodegradable, and replenishable on a yearly basis.
Corn-based biodegradable plastics have won a national award, thanks to Cornell chemist Coates' innovative work in developing polymers that can be easily absorbed by the environment. His research has also led to new applications, such as sutures and drug delivery systems.
A new type of degradable polyethene, SPI-TEK, breaks down in five years and allows other organic materials to decompose, increasing landfill site capacity. Bayer is also testing a new 100% degradable polyester suitable for industrial production in agriculture and food sectors.
University of Illinois food scientists create water-resistant, plastic-like containers using zein and fatty acids, which can be naturally decomposed. The new process produces biodegradable plastics from corn gluten meal, addressing the global demand for eco-friendly packaging materials.
