ABSTRACT
The planet goes through a period of negative changes due to the many forms of
pollution. One of these pollutants is the improper disposal of plastic packaging that
interferes with the quality of life for all living beings, causing flooding and
contaminations of soil and water with chemicals in these materials. Initially to
alleviate this problem the country needs to invest in environmental awareness should
start early in schools and monitor the student until the end of his academic life.
Another point that is noteworthy is the greater incentives, support and investments in
the development of green materials that are extracted from renewable sources, rising
to consume fewer non-renewable resources, always seeking the conservation and
preservation of the environment. This research will approach the advantages and
disadvantages in use biodegradable plastic in the production of famous supermarket
bags and the benefit it brings to the environment the use of biodegradable materials.
When degraded in composting stations the material can take about 3-6 months to
fully degradation, without causing any damage to nature. Traditional plastics such as
LDPE, HDPE, PP, PVC, PE and others can take up to 500 years to degrade in
nature, biodegradable plastic decomposes 20 times faster than common plastic. The
term green plastic is applied to compounds derived from renewable sources (such as
those produced from cereals and other vegetable oils or) or that are biodegradable
(in this case, must meet strict standards relating to the ability of biodegradation and
composting).
