About plastic recycling
The recycling of plastic bottles consists of the reuse of plastic material, with the intention of reducing the quantity of refuse destined for landfills. The idea is to convert as much waste as possible into products to be reused on the market. Plastic containers are used in various sectors, according to their level of contamination. The removal of residue in all bottles is a very delicate task during the recycling process.
The advantages of PET
To convert the recycled plastic into material suitable for use with food and other industries, the bottles are hydrolysed and finally go through a process of purification, essential for their conversion into a new form. In particular, PET (polyethylene terephthalate) is the material commonly used for plastic bottles and it can be recycled via two different methods: mechanically, which is the most economical method, but one which does not permit the reuse of materials for food purposes, and chemically, which can revert polymers to their original state, breaking them down into a series of raw materials that can subsequently be used for the production of new PET.
