A lot of products these days are claiming to be recyclable, biodegradable, made from recycled materials, etc. An item that is biodegradable is a product or material made from an eco-friendly material that decomposes in landfills or other environments such as people litter or roadsides. Natural materials are biodegradable because they come directly from other natural fibers or plants. A large majority of the natural fibers are produced by plants. These kinds of materials are made from cotton – the largest plant fiber. Jute is the second largest plant fiber in manufacturing material. Natural fibers are also produced by animals. Materials like wool from sheep and alpaca fibers will decompose naturally. The fibers are woven into fabric and it is the fiber that is biodegradable.
