Scientists from Monash University in Australia have created a new type of plastic biodegradable based on food waste. It can be an environmentally friendly replacement for oil -based packaging.
The world plastic production volume is estimated at 400 million tons per year. This material still exists for a long time in the environment, causing pollution.
Australian scientists have presented a technology that allows you to turn your food from food waste into Biopolyme polyhydroxycanots (PGA). They chose bacteria strains and mixed them with polymers. Management results to create films, similar to conventional plastic.
The authors of the scientific work focused on two types of earth bacteria: Cupriavidus Necator and Pseudomonas Putida. They are fed with a balanced diet of sugar with a certain amount of salt, nutrients and trace elements.
Over time, bacteria begin to accumulate natural plastic inside their cells. Scientists removed it with the help of solvent and extremely thick films about 20 microns. Observations show that Cupriavidus Necator is difficult, and Pseudomonas Putida is softer and more flexible. Combining these two options, you can adjust the different attributes of the film, report to microorganism cell plants.
Previously, scientists estimate the damage from plastic pollution. It reaches about 1.5 trillion dollars a year. Alastms causes illness and death of everyone of all ages and is the cause of economic losses.
