How do you deal with plastic bags from the
supermarket? Throw them away or recycle them? How about eating them?
The bags are not harmful to the
environment, Humans and animals can safely eat them. Indian company EnviGreen
has made a bag with natural materials. It looks and feels just like plastic,
but can break down(分解) easily.
Ashwath Hedge who set up the EnviGreen
Company spent four years doing experiments(实验) with 12
natural materials. They include potato, corn, vegetable oil and banana. He made
the materials into liquid(液体) and used the liquid to
make the bag.
Although
the EnviGreen bag is more expensive than a common plastic bag, it has many
advantages. According to the Wall Street Journal, it takes 1,000 years for
common plastic bags to break down. But an EnviGreen bag can naturally break
down in less than 180 days. It also breaks down in less than a day in water,
and in less than a minute in boiling water. Hedge was happy to show it in
his interview, he put an EnviGreen bag in water and ate it with a smile.
There are more than 15,000 tons of plastic
waste in India every day. But only 9, 000 tons are processed. In China, 3
billion plastic bags are used every day. Maybe the EnviGreen bag could be a
solution(解决方法) to the world problem of plastic
pollution.
