What Is Biodegradable

1. Going Green is the only way to
save the planet Earth.
let's talk about how we can lower our dependency
on fossil fuels,

2. 
Going Green is the only way to save the planet Earth
Energy & The Environment is the One Issue We Have to Get Right

To completely switch petroleum-based to corn-based plastic
Giant consumer industries must mandate vendors to develop
sustainable content in cushioning and corrugate packaging

Ensure that 75% of packaging components are recyclable.

Government to regulate the cost structures involved in the raw
material.

Biodegradable and Recyclable must be the voice of the world.

Governments to mandate strictly for Biodegradable products.

3. What is Biodegradable

Biodegradation is the process by which organic substances are broken down
by the enzymes produced by living organisms. Organic material can be
degraded aerobically, with oxygen, or anaerobically, without oxygen.

Biodegradable matter is generally organic material such as plant and animal
matter and other substances originating from living organisms, or artificial
materials that are similar enough to plant and animal matter to be put to use by
microorganisms. Some microorganisms have the astonishing, naturally
occurring, microbial catabolic diversity to degrade, transform or accumulate a
huge range of compounds including hydrocarbons (e.g. oil), polychlorinated
biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), pharmaceutical
substances, radionuclides and metals.

Major methodological breakthroughs in microbial biodegradation have enabled
detailed genomic, metagenomic, proteomic, bioinformatic and other high-
throughput analyses of environmentally relevant microorganisms providing
unprecedented insights into key biodegradative pathways and the ability of
microorganisms to adapt to changing environmental conditions.

4. What is sustainable
Meeting the needs of the present without
compromising the ability of future
generations to meet their own needs.
Applied in an economic context, a business
is sustainable if it has adapted its practices
for the use of renewable resources and is
accountable for the environmental impacts
of its activities.

5. What is a Biodegradable plastic

Biodegradable plastics are plastics that will
decompose in the natural environment.

Bioplastics (also called organic plastics) are a
form of plastics derived from renewable biomass
sources, such as vegetable oil, corn starch, pea
starch, rather than fossil fuel plastics which are
derived from petroleum.

6. Now how can we make
Biodegradable plastic
Plastics can be produced from starch. Starch is a natural
polymer. It is a white, granular carbohydrate produced by plants
during photosynthesis and it serves as the plant's energy store.
Cereal plants and tubers normally contain starch in large
proportions. Starch can be processed directly into a bioplastic
but, because it is soluble in water, articles made from starch will
swell and deform when exposed to moisture, limiting its use.
This problem can be overcome by modifying the starch into a
different polymer. First, starch is harvested from corn, wheat or
potatoes, then microorganisms transform it into lactic acid, a
monomer. Finally, the lactic acid is chemically treated to cause
the molecules of lactic acid to link up into long chains or
polymers, which bond together to form a plastic called
polylactide (PLA).

7. Uses

PLA can be used for products such as plant pots and disposable
nappies. It has been commercially available since 1990, and certain
blends have proved successful in medical implants, sutures and drug
delivery systems because of their capacity to dissolve away over time.
However, because PLA is significantly more expensive than
conventional plastics it has failed to win widespread consumer
acceptance.

But if the Governments play a major role in mandating the prices of the
bio based plastics, then only this plastic can win the acceptance of the
consumer.

This has to come down from higher up.

8. Packaging
WalMart is beginning to switch from
petroleum-based to corn-based plastic
packaging. The first substitution, involves
114 million clear-plastic clamshell
containers used annually by the retailer for
cut fruit, herbs, strawberries and brussel
sprouts.

9. Future
The future certainly looks good
