What is biodegradable plastic ?

It usually takes hundreds years to decompose plastics widely used in the natural environment or sometimes they do not degrade, thus they are accused of environmental contamination because non-degradable packing materials, plastic bags or styrofoam are not properly handled. In addition hundreds of thousands of plastic products (used plastic bags, nets) are dumped into the sea every year. These wastes are accumulated in the ocean and cause damage to the fishing grounds and marine ecosystem. Therefore, the need for biodegradable materials that do not cause environmental problems gets stronger. That’s why biodegradable plastics have emerged.

Biodegradable plastics have the same physical properties with general plastics, but they are decomposed by the microorganisms (bacteria, molds and algae) existing in the nature producing water, carbon dioxide and others.

Recently research and commercialization of biodegradable high polymers gather speed to tackle with aggravating environmental problems all over the world including advanced nations such as USA, Japan and Germany.


Generally biodegradable plastics are derived from starch or aliphatic polyester.

 

As it is believed that petroleum, the primary material for packing materials and artificial fabric, cannot be sufficiently supplied in 20-70 years, biodegradable plastics use completely recyclable materials and have stable source of supply.

In addition, they have similar properties to those of existing plastics and have price competitiveness against petrochemical products.


It is forecast that price competitiveness will get stronger against the depletion of petroleum



The global penetration of bio-polymer, vegetable plastic and a material of your dream, will allow for the replacement of plastics and provide well being for mankind.
