The future of plastic bags handling problems, scientists fancy eat the insects?
Scientists fancy eat insects, how to break down the plastic bag?
Caterpillars may be the key to our solution to the growing problem of plastic waste. A group of researchers in Spain, when doing some routine hive maintenance, accidentally discovered a caterpillar that seemed interested in plastic.
Federica Bertocchini of the Institute of Biomedical and Biotechnology at Cantabria removed the caterpillars from the hive and placed the beeswax pests in plastic bags for disposal. After a while, she found the caterpillar to bite the plastic bag, and all the plastic debris. Later she and her team confirmed that caterpillars could chew the plastic, and now they wanted to develop a quick decomposition of polyethylene – used to break down plastic bags – extract enzymes from caterpillars.
The team found that 100 caterpillar moth caterpillars could bust a supermarket shopping bag in an hour and could consume 92 milligrams of plastic for half a day – just over 3% of a shopping bag. Considering that under normal conditions, plastic bags need at least 100 years of decomposition, Bertocchini said: “That ‘s already fast.
In order to ensure that caterpillars really digest the plastic, the group crushed some of them and laid a thin layer on the polyethylene film. In 14 hours after repeated smear, caterpillar decomposition of 13% of the plastic. The group also found
The evidence of ethylene glycol, it is evidence of polyethylene decomposition.
Bertocchini said: “Our study is the first to show that this species is chemically depolymerized to resolve the scientific research of plastic polyethylene.” This ability of the caterpillar may be due to some of its intestinal microbes.
Dr. Wei-Min Wu of Stanford University, who studies all kinds of plastic edible species, says the results are exciting. But he said that this caterpillar paste is much higher than the biodegradation rate of any degraded polyethylene bacteria found so far, indicating that the situation within the caterpillar intestine is more complex than the microbial decomposition.
Bertocchini hopes to break down the plastic is a single enzyme. “If this is the case, future separation, mass production, for biodegradable plastics is just around the corner.”
At the same time, it is not unreasonable to think that we will continue to discover the idea of digesting plastic creatures. But our plastic problem will not miraculously disappear. On the other hand, these creatures will not begin to devour our precious plastic products.
Bertocchini said, “These creatures do not live with edible plastic, they eat plastic in order to get rid of it, or get the food behind it.I do not know whether there will be biological in the future will evolve to specifically eat plastic, but so far This is not the case. “
