Bio-based polyolefin is a type of plastic made from renewable, plant-based sources such as vegetable oils or starch. It has a similar chemical structure to traditional polyolefin plastics, but is much more environmentally friendly and sustainable. The renewable sources used to make bio-based polyolefin can be quickly replenished, reducing the need for the use of non-renewable petroleum-based materials. It is also biodegradable and can be recycled, making it an ideal material for a wide range of applications.
