Recycling is a process that converts waste materials into reusable materials in order to reduce waste, decrease consumption of raw materials, lower energy usage and emissions. It involves sorting recyclables like plastic, cardboard, cans, glass, paper and metal at home before delivering them to a local collection station. The waste is then processed at a recycling plant where materials are recovered and converted back into usable items. Recycling helps preserve the environment for future generations by reducing the amount of waste sent to landfills.
