Biodegradable Plastic Bags: What Are They

Biodegradable plastic bags are a hot subject of environmental protection. The national government propagandize everyone to use these bags instead of the normal bag; further, they issue a policy to forbid the use of plastic without biodegradable additive.

What are Biodegradable plastic bags?

Biodegradable or often called decomposable bags are the kinds of polyolefin plastic bags that are made using a material that allows the bag to decompose completely after a period of time by the action of naturally-occurring micro-organisms such as bacteria, fungi, or controlled degradation through the incorporation of degradant to undergo accelerated oxidative define degradation initiated by natural light, heat and oxygen. They completely destroyed within 3 months to 5 years.

Classification

There are many ways to classify these biodegradable bags. One way is degradable conditions, there are two main types: Biodegradable plastic bags and plastic degradable bags.

Bio-degradable made from farmed products like cornstarch and additive; are decomposed in the aerobic condition, so they can not degrade in the natural environment.  In addition to protecting the environment, biodegradable plastic bags are used to create energy.

It breaks down the elements of carbon dioxide, water and metals. So that the bioreactor or wet landfill are designed to encourage the break down of natural matter and capture the methane emitted for energy generation.
