Bio Plastic
Definition of Bio Plastic
Bio Plastic, one of the typical bio materials, refers to organisms that are used for chemical energy and includes firewood, forest and gas of organisms.
A dictionary definition of Bio Plastic is living things such as plants or microorganisms that are used for energy sources. The amount of biomass that is produces on Earth for a year is equivalent to total oil reserves, so if used properly, there is no danger of depletion. But in a broader meaning, it also refers to renewable organic substances such as plants, trees, agricultural products, forage crops, agricultural waste and residues, forest wastes, crumbs, aquatic plants, animal excretion, municipal wastes and other wastes.
Types of Bio Plastic
- - Biodegradable Plastic
- It refers to plastic that contains more than 70% biomass which comes from plants such as corns (in case of Japan, more than 50%).
- There still are problems such as price competitiveness, risk of degradation during distribution, weakening of physical property but it is being widely used as disposable product.
- - Bio Base Plastice
- It refers to plastic that contains more than certain amount of biomass.
- Mainly used in food packaging products, industrial goods, agricultural and horticultural area that has more than one year of expiration dates.

- - Carbon Neutral(Carbon Neutral)
- Plants grow by absorbing CO2 in the atmosphere, so even after being chemically degraded after use, it would not increase the gross CO2 level in the atmosphere, so it is carbon neutral.

Eco Packaging (Eco-friendly packaging) Category
Category of eco-friendly is very broad, but generally, it is categorized in 4Rs.
Recently it is sometimes categorized in 5Rs, including “resign,” which is a compound word of “recycle” and “design,” but it is not common for now.
-
REDUSE
Policy to slow down
environmental degradation
by reducing the amount
of every waste and
garbage produced. -
RECYLE
Create economic value by
collectingall sorts of
resources, making good
used of them from waste
to resources and recycle them. -
REPLACEMENT
The environmental friendly policy
to replace materials made of
fossil fuelswith environmental
friendly materials,replacing
petroleum energy with
environmental friendly
alternative energy. -
REUSE
Replace plastic, which is made
of recalcitrant synthetic resins,
which comes from fossil fuels,
with materials made of
biodegradable, biophotolysis,
incineratable substances.
Do not dispose of the products
used once, but use it again
