Compostable plastics are usually made from what would be known as natural resins such as cellulose, lactic acid, starch, etc. These types of plastics are biodegradable but more specifically compostable.
Some of the natural resins require an initial mechanical breakdown from high heat before microbes can biodegrade the plastic. This type of environment is usually only found in industrial composting facilities.
There are other plastics which utilize an organic additive to render standard plastics biodegradable by microbes.
It is important to keep in mind that standard plastics are made from fossil fuels which is a natural material (fossilized algae).
Cellulose and it derivatives like Bakelite are historic natural resin plastics. There is also an upswing of biodegradable plastis which include starch molecules in their molecular structure.The whole field of bioplastics is growing. These include:Starch-based plasticsCellulose-based plasticsProtein-based plasticsAliphatic polyestersPolyhydroxyalkanoates (PHA)Polyamide 11 (PA 11)Polyhydroxyurethanes (PHU)Lipid Derived Polymers

No. No plastic is biodegradable unless it's made from vegetable oil. Most plastic is made from fossil fuel oil.
no, plastic can never be considered a biodegradable waste because it cannot be made into simpler substances by the microorganisms
If the twine is made from a natural fiber, like hemp, sisal or even cotton, then it is biodegradable.Some twine is made of plastic. This is not biodegradable.
Biodegradable plastic.
Metal, resin, or wood resin being plastic
Cloth is biodegradable and is readily broken down if it is made from natural materials (cotton, linen, flax, silk). This makes it an environmentally friendly material. Cloth made from plastics (polyester, nylon, etc) is not biodegradable, but, like plastic, takes hundreds of years to break down, and when it does, it is often just into tiny pieces of plastic the insects, animals and birds eat by mistake.
Fiberglass is made from sand and other natural minerals, and then coated in resin or plastic. It has many different uses and is considered to be very strong.
No there are some plastic bags that are biodegradable
Most T-Shirts are made of Cotton, and since Cotton is a Natural Fabric, it is biodegradable. If a T-Shirt is a blend (containing more than one type of fabric), and one of the blended fabrics is NOT Natural, the T-Shirt would ONLY be partially biodegradable (the portions made up of the Natural fabrics). Nylon & Polyester are Fabrics which ARE NOT Natural; therefore NOT Biodegradable. Cotton & Hemp are Fabrics which ARE Natural; therefore they ARE Biodegradable.
An organic plastic is one that has been made using carbon and other biodegradable compounds. This means that it will biodegrade easily and won't fill up landfills and ruin the environment. For example, there are some types of plastic made out of potatoes, and others made of different vegetables of natural fibre.
