Replacing plastic

The material is able to combine with non-toxic chemicals. Moreover, it does not require preliminary processing.

Scientists from Stockholm University have created a natural analogue of plastic based on an organic substance – lignin. Writes about this scientific journal New Atlas.

This material was not chosen by chance. It is thermosetting and changes shape when heated. Plus, it can be used many times.

Lignin is an organic polymer that makes up the cell walls of plants and trees.

It is found in wood waste from the pulp and paper industry. It is known that today it is often used in the manufacture of innovative batteries, carbon fiber reinforced plastic and concrete.

Lignin is able to bind with non-toxic chemicals. Moreover, it does not require preliminary processing.

“Due to its dynamic covalent bonds, the material can be molded over and over again with relatively little heat. It can also be soft and hard,” said University professor Mika Sipponen.

And in case of deformation, it does not lose its strength.

We will remind, earlier scientists came up with, how to make vanillin from a plastic bottle.
