Plastic is a mixture of a polymer, often obtained by the transformation of petroleum or natural gas, and various additive substances. It is an inexpensive material which has the advantage of being easy to shape, lightweight, airtight, insulating, elastic and extremely resistant.
After it has been used, plastic is difficult to recycle  . Only 20% of the plastic we throw away is reused or incinerated to produce energy. The rest is assigned to landfills or ends up in the environment. To limit our production of non-recyclable plastic waste, it is therefore crucial to reduce consumption!
