Recycling is a complicated and sometimes imperfect process of converting waste materials into new materials. This process allows us to reduce the consumption of fresh materials and limit energy usage and pollution. While recycling can be very useful, it has often been falsely heralded as the solution to plastic pollution, it is unfortunately not all that simple. Recycling is a hugely energy-intensive process and can still be very polluting. Furthermore, plastic products have a huge variety in composition, colour, weight and size – meaning they cannot be recycled together. For example, coloured plastics are much more difficult to recycle and therefore have little market value for Materials Recovery Facilities (MRFs) to recover.
