Japanese scientists created heat-resistant bioplastic on the base of wood

Японские учёные изобрели безопасный термостойкий пластик из древесиныIt is not worse than traditional plastic in strength but during heating it does not disengage   harmful agent and environmentally safe because it decomposes naturally quickly and without rest.
As it is known plastic is one of the greatest problem of our time. It is difficult to imagine the development of modern civilization but at the same time any plastic is harmful for the planet the only factor of its existing because it produces from non-renewable natural resources – oil, gas and coal. Plastic almost does not dispose naturally and it means it destroy soil and saltwater ecosystem, it enters into atmosphere and collects in organisms of creatures.

It influences people directly. European countries even refuse from disposable cutlery: during heating the plastic harmful for health and life of the people discharge from it.
Japanese researchers decided two problems at the same time. They created environmentally safe plastic which does not discharge harmful material during the heating. Natural wood is on the base of new material. On physical-chemical values material is not worse than traditional kind of plastic: it has the same strength, flexibility but at the same time is does not discharge harmful material during high temperature and it decompose quickly naturally.  
Researches processed woodchip with aqueous liquid containing hydroxide and sodium sulphide and got cellulose. Then we mixed it with chemical agent and molecules which in complex promoted the creation of heat-resistant film.
 The final product is light organic plastic which does not have in its context heavy inorganic fillers. It has the highest heat-resistance from all known kinds of plastic: it withstand temperature more 740 degree Celsius.
 «Besides obvious advantages of innovation cellulose-molecular material it will make a contribution to the development of more stable society », — the team of designers declare.
