Algae extract packaging may soon replace plastic
The research team has developed a technology for the production of durable and biodegradable food packaging from alginate.
Most of today’s films are made of plastic, which contains three toxins that stimulate the onset of cancer in the human body. Disposable plastic products are also a major environmental pollutant.
Technologists from the Oceanological University of China have developed a new durable food packaging that completely degrades in natural conditions in 6–12 months and can withstand temperatures from -80 °C up to 120 °C. It is completely safe for health because it is made from a viscous rubbery substance extracted from brown algae, called alginic acid..
The structure of the alginate itself is brittle, but the formation of a film using double calcium ions allowed to achieve the required level of strength.
After 8 years of research and thousands of experiments, the group has filed a patent application, but still continues to improve the technology..
Using agar-agar, also extracted from algae, scientists have recently created biocompatible fiber optic.
