Note that polyurethane is required for many industries, as it is suitable for use in mechanisms with increased load. At the same time, it is not without its drawbacks. So, its decomposition is counted in centuries.

At the same time, thanks to the scientific work of Canadian scientists, this problem can be avoided. They have implemented a biodegradable alternative that uses fish waste to produce it.

Polyurethane is produced from fish waste in several stages. First, the researchers extract the fish oil from the harvested material, and oxygen is added to make the epoxies. Subsequently, a substance resembling molecules in epoxy resin is obtained. Further, the resulting epoxies react with carbon dioxide, which helps to bind the resulting particles with nitrogen-containing molecules from the cashew nut shell.
