New Types Of Biodegradable Plastics

However not all the current biodegradable plastics have achieved this aim.

New types of biodegradable plastics.

When exposed to seawater the new plastics can dissolve in as few as 20 days. New types of plastics have been produced in recent years to address the plastic pollution problem by trying to shorten the time needed to degrade them especially in natural conditions. Biodegradable plastics are renewable and can be recycled easily. Retrieved september 28 2020 from www.

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. Type of biodegradable plastics there are two main types of biodegradable plastics. New biodegradable plastic is tough flexible. Biodegradable plastics are commonly produced with renewable raw materials micro organisms petrochemicals or combinations of all three.

Biodegradable plastics are plastics that can be decomposed by the action of living organisms usually microbes into water carbon dioxide and biomass. While the words bioplastic and biodegradable plastic are similar they are not synonymous. 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. Types of biodegradable plastics additives.

They require less energy for production reduce dependency on the use of oil and are non toxic. In both cases degradation begins with a chemical process oxidation and hydrolysis respectively followed by a biological process. Biodegradable plastic is also known as oxo biodegradable plastics and d2w technology is used which is the additive that converts plastic into biodegradable material. They are made of polyurethane modified to incorporate a biodegradable compound known as plga which is used in medical.

Both types emit co 2 as they degrade but hydro biodegradable plastics can also emit methane. There are different types of biodegradable plastics which offer different degrees of degradability and generally require specific conditions in order to do so.
