Plastic products labelled “eco”, which are considered safe for the environment, is actually stored in it for years.
Scientists from the University of Plymouth has tested several types of packages: oxoralen (which collapse under the influence of oxygen), biodegradable, compostable and conventional plastic one.
Products exposed to different natural environments: soil, air and water.
It turned out that over the long term are not fully disintegrated, none, reports
“What is our life? Game!”“World mind games”: a premiere at the World Best results were obtained in compostable packages – they broke up just three months stay in the sea. But scientists are in no hurry to optimistic conclusions. Perhaps from products left microparticles, whose influence on ecosystems is yet to be explored.
“Biodegradable” bags buried in the ground for three years, and then they were so durable that they can be used for its intended purpose – to carry shopping from the store.
Compostable bag, survived underground for 27 months, but then was torn by the slightest exertion.
Air plastic products collapsed in nine months, but not completely disappeared, but simply broke up into smaller pieces.
The authors of the study concluded that the safety of such products for the environment are probably exaggerated. The same compostable bags can degrade only under certain conditions, including sufficiently high temperature (to 50 degrees). This is possible in specialized plant but not in vivo.
Earlier, Greenpeace questioned 10 major supermarkets and found that they annually produce 1.1 billion disposable plastic bags, 1.2 billion of packaging for fruits and vegetables and 958 million multi-functional plastic bags.
Environmental pollution by plastic is becoming more and more rampant, despite attempts by some countries to limit the use of this material.
Completely abandon plastic the world is not ready, and perhaps the only solution is to make it less durable. But, as the study showed, this problem is still not solved.
Earlier it was reported that the microplastics have reached the deepest parts of the Pacific ocean, including Mariana.
