Israeli scientists create “sustainable plastic” from seaweed
At this moment in history in which the abnormal proliferation of sargasso in the Atlantic Ocean is affecting not only the tourism industry, but marine and coastal ecosystems as well, scientific discoveries arise that can contribute to the use of these algae to produce 100% biodegradable substitutes for plastic, that could provide solutions to many of the environmental problems created by human beings in the last century.
Tel Aviv.- Researchers in Israel have developed a new process to produce a “natural polymer” that is derived from microorganisms that feed on seaweed. In a statement, scientists from the University of Tel Aviv (
TAU) said that bioplastic polymers can be produced without soil or fresh water, resources that are getting more and more scarce in much of the world.
The polymer is derived from microorganisms that feed on algae. It is biodegradable, produces zero toxic waste and is recycled into organic waste.
To achieve this, they have used Haloferax Mediterranei, a bacteria that feeds on the carbohydrates present in algae and metabolize them in polyhydroxyalkanoates (PHA), a type of polyester produced in nature through the action of bacteria, usually by fermentation of sugar or lipids.
PHAs are one of the most promising research fields, since the resulting bioplastics are completely biodegradable and do not generate any kind of toxic waste whatsoever.
