Products made from this material are more environmentally friendly than from ordinary plastic.
Ecologists call bioplastic a means of combining with nature, since it is fundamentally different from ordinary polyethylene waste, which is heavily polluting the world around us, reports Chronicle.info with reference to Esoreiter.
Recycling or restrictions on the use of plastic already familiar to us have practically no effect. That is why scientists are developing more and more new types of biologically pure polymer, which easily and quickly decomposes in natural conditions, without causing any harm to nature.
However, what is the problem here, if the bioplastic has long been invented, why does it not replace the polyethylene produced from oil? After all, biodegradable polymers, say, PLA, PBS, obtained from sugar cane or corn, have been produced in the world for several years.
But the fact of the matter is that the production of these biopolymers requires additional acreage, fertilizers, fresh water, which ultimately turns into almost the same catastrophe for nature, not to mention the fact that these resources are already lacking on our planet. Moreover, such a bioplastic is too expensive, which makes it not even have a commercial future ...
TAU (University in Tel Aviv) was finally able to create a biopolymer that does not require either land resources or fresh water. You can get it from the waste of microorganisms that feed on algae. Such wastes are easily processed into organics, from which the Israelis obtained a unique biodegradable polymer - polyhydroxyalkanoate, or PHA for short.
Professor Michael Gozin and Dr. Alexander Golberg became co-authors of this invention. Any product or the same packaging from PHA, scientists say, easily decomposes in nature without causing any harm to it. Moreover, the creation of the polyhydroxyalkanoate itself does not require any plants, which means farmland and fresh water. This will allow producing a relatively cheap and effective bioplastic in any country where it is possible to use marine resources, that is, algae.

Currently, Bioresource Techno reports, TAU scientists are refining their invention, selecting the most optimal combinations of “algae-bacteria” in order to reduce the cost of such bioplastic and create various modifications of it that meet all kinds of market needs in plastic products and packaging.
