Scientists-chemists at the University of California have created a plastic that can completely decompose in water or compost pits. It can be used to make environmentally friendly food packaging and plastic utensils.
Scientists have created special substances that, when added to plastic, allow it to fully decompose in a few days or weeks in standard compost or tap water.
So, a pinch of enzymes, “chews up” the polymers, which can make biodegradable plastic packaging and utensils that can be composted. Also, when the film of plastic is moderately heated, the attached enzymes decompose into ordinary compost or simple tap water within days to weeks.
According to scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory, adding polymeric enzymes to plastic helps it fully decompose in a normal environment – a compost pit or water.
Over the past 70 years, the world has produced more than six billion tons of plastic, of which only 9 percent has been recycled and another 12 percent incinerated. The bulk of plastic is scattered in garbage dumps, floats in water, and penetrates living organisms. Its microparticles may settle in living tissues and cause various pathologies.
Scientists have stated that by 2045, men on Earth may lose the ability to reproduce due to the effects of chemicals that alter human hormones.
