There are many biodegradable plastics that are invented.
A material is biodegradable if it can be broken down by the biological processes. Plants, as well as animal matter are examples of something that is biodegradable, because it can be broken down and absorbed back into the environment.
Biodegradable means it will decompose naturally over a period of time. With some materials it may take only a few weeks, others may take longer. A few things that are not biodegradable are materials such as some plastics, metals, and some petroleum based products.

The carrying capacity of some of the early snowmobiles was 22 people.
Things that can be eaten by bacteria, fungi or other microorganisms are referred to as being biodegradable. These things include almost everything except glass, plastic (which biodegrades in millions of years), some other manmade materials and, unfortunately, Styrofoam.

Some plastic is non-biodegradable, in the sense that it takes longer than several lifetimes for the plastic to disintegrate. A glass bottle is essentially non-biodegradable.
Here are some sentences.A proper sentence has a subject and a verb.Use proper etiquette at the party.
A material is biodegradable if it can be broken down by the biological processes. Plants, as well as animal matter are examples of something that is biodegradable, because it can be broken down and absorbed back into the environment.
Some examples of biodegradable include paper, cotton rag, banana peels and many more. These are products that are broken down by micro-organisms found in nature which means they do not harm the environment.
I could write you as sentence but it would probably be an lousy example.
Some example of BIO-DEGRADABLE THINGS: paper, juice, chicken bones, clothes... anything that can be broken down by organisms NON BIO-DEGRADABLE THINGS: plastic toys, plastic bags, glass, steel, synthetic rubber.
Non-biodegradable materials are things that can't be broken down easily by natural processes. For example, plastic shopping bags would take thousands of years to be degraded (broken down). Some examples of non-biodegradable materials are: plastic polystyrene (styrofoam) metals foams glasses silicon-based materials/circuit boards oil ashes
Some examples of biodegradable and non-biodegradable is: Biodegradable : leaves, flowers, kitchen waste (wet) animal or human excretion, seedless fruit, handmade bags, dead animals or human beings wood, wires without coating. Non-biodegradable: plastic products, nylon products, synthetic products, silk products, clothes, dry kitchen waste, glass products.
Many plastics; some metals especially gold and stainless steel; glass and earthenware;asbestos.
