Plastics are made from raw materials like natural gas, oil or plants,
which are refined into ethane and propane, the polymerisation process
turns these components into plastics through heating and moulding processes.
Recycling one metric tonne of plastics can avoid the emissions of 2.5metric tonnes of CO2 when produced from virgin raw materials.
