Found alternative to the plastic, which do not damage nature
Source:
each year the world produces several million tons of plastic
for the environment has already been written numerous articles, including on our website. While regularly conducted and the development of new forms and types of material that would be less harmful to the environment. In order not to miss such materials in the future, we recommend that you sign up for our and we, meanwhile, will tell you about the new invention — the alternative material, which in the future can replace .
what created an alternate plastic?
According to the editorial Board Eurekalert, the development of responsible employees of Aalto University and technical research Centre (VTT). Both of these companies are located in Finland. Researchers have created a really new and unique material by combining wood fiber cellulose and silk protein extracted from filaments of the web. The result is a very durable and elastic material, which can be used in the future .
Nature offers the perfect ingredients for the development of new materials, such as solids and easily accessible cellulose and rigid and flexible silk, which we used in our study — says Otten of the leading authors, Professor Aalto University Markus Linder. The advantage of these materials is that, unlike plastic, they are biodegradable and are not harmful to the environment.
To create plastic scientists ispolzovali birch pulp that «broke» smaller cellulose nanofibers. Then, like a grid, connected in a rigid frame. At the same time, the resulting cellulose has implemented a network of adhesive matrix of spider silk. In the end, cellulae gave material softness and flexibility, and silk — strength. External pranaam new material very much like plastic.
What is important, silk is known to be created in the wild mulberry silkworms. However, the Finnish researchers used a «artificial» silk, reproduced genetically modified bacteria with the changed DNA, programmed for the production of silk. This silk is much cheaper to produce, and the composition is not much different from the natural.
Since we know the structure of DNA, we can copy it and use for the production of silk protein molecules, which are chemically similar to those that are in the threads of the web — says Professor Linder. Our work illustrates new possibilities for protein engineering. In the future we would be able to produce similar compounds with different properties.
Introducing silk threads between cellulose fibers
The question May arise: but as for the production of plastic alternatives will need to massively cut down trees for the purpose of production of cellulose? Actually, no. Now scientists are actively working on finding the cheapest way of production of artificial cellulose with bacteria. Of course, a similar development is already there, but the whole process of creating alternatives plastico output should give a product, which . Otherwise a large part proizvoditley won't even look in the direction of new technologies.
