Scientists have learned how to make heaters from plastic bottles.

Chemists have developed a technology that makes it possible to make foamed polymers from used plastic bottles. The technology makes it possible to process polymers using their initial components as a source of chemical raw materials. Of these, you can make high-quality heat and sound insulating materials, for example, foam rubber. In this way, other substances can be obtained, such as a wood preservative or a viscous resin for the production of rubber.
