Biodegradable plastics are plastics degraded by microorganisms into water carbon dioxide or methane and biomass under specified conditions.
New types of biodegradable plastics.
Types of biodegradable plastics additives.
Type of biodegradable plastics there are two main types of biodegradable plastics.
Biodegradable plastics can be biobased or fossil fuel based.
Biodegradable plastics are plastics that can be decomposed by the action of living organisms usually microbes into water carbon dioxide and biomass.
Both types emit co 2 as they degrade but hydro biodegradable plastics can also emit methane.

Biodegradable plastic is also known as oxo biodegradable plastics and d2w technology is used which is the additive that converts plastic into biodegradable material.
However not all the current biodegradable plastics have achieved this aim.
Potential for earth friendly plastic replacement.
Are useful in litter environments where heat light and air can force the plastic to break into diols small pieces below 500 daltons bacteria and fungus produce a saliva like product that can dissolve the diol.
They require less energy for production reduce dependency on the use of oil and are non toxic.
There are different types of biodegradable plastics which offer different degrees of degradability and generally require specific conditions in order to do so.
They are made of polyurethane modified to incorporate a biodegradable compound known as plga which is used in medical.
To guide consumers in their decision making and give them confidence in a plastic s biodegradability universal standards have been implemented new materials have been developed and a compostable logo has been introduced.
In both cases degradation begins with a chemical process oxidation and hydrolysis respectively followed by a biological process.
New biodegradable plastic is tough flexible.
When exposed to seawater the new plastics can dissolve in as few as 20 days.
Biodegradable plastics are renewable and can be recycled easily.
