Plastic was one of the greatest inventions of the twentieth century in technology, but the environment is a curse, since it is not biodegradable, and contains carcinogens and other toxic substances that can cause cancer. To save it, German scientists have invented a liquid timber, which could replace plastic almost all uses that are given today.
To make matters worse, the plastic is based on petroleum, a nonrenewable resource that is increasingly expensive and highly polluting. But the new chemical invention could replace him calmly and with a renewable source, wood.
The team of German scientists, led by Norbert Eisenreich, the Instituro for Chemistry Pfinztal technology, have a substance called Arboform, which is basically liquid timber.
is derived from wood pulp and can be mixed with a wide range of materials to create a non-toxic alternative to petroleum-based plastic.
"The industry of wood pulp separated into three components," says Emilia Regina Inone-Kauffmann, one of the researchers, "lignin, cellulose and hemicellulose. Lignin is not needed in the process of making paper. Our colleagues remaining lignin mixed with fine natural fiber made from wood and natural additives like wax. From this we produce a granulated plastic can be melted and shaped. "
The end product can resemble a highly polished wood or plastic also typical. And it could be used in all areas where plastic is used today.
To make matters worse it is easy to recycle plastic wood. Just have to wait to do business.
