Scientists have discovered microorganisms that can degrade polyurethane at low temperatures
Scientists have found microbes in the Alps and the Arctic that can digest plastic at low temperatures, which could be a valuable tool for recycling. Many microorganisms that can do this have been found, but they usually only work at temperatures above 30°C (86°F). This means that they are very expensive to use in industrial practice due to the need for heating. This also means that using them is not carbon neutral. Scientists at the Swiss Federal Institute of Research WSL have discovered microbes that can do this at 15°C, which could lead to a breakthrough in microbial

Scientists have developed polymers with shape-memory properties. This new material combines efficient
Scientists use plastic waste and waste cooking oil to make rigid polyurethane foam
Scientists in Iran use a mixture of waste cooking oil and plastic waste to make polyols. The team at Imam Khomeini International University uses these polyols to make rigid polyurethane foam. Used cooking oils can be epoxidized, and these epoxides are then converted into bio-based polyols by reacting with some chemical agents such as ethylene glycol, glycerol and triethanolamine. Bio-based polyols can also be prepared by transesterification of oils. Crude glycerin is the main by-product of the transesterification process of biodiesel preparation from used cooking
