Recycling technologies refer to the various methods and processes used to convert waste materials into reusable resources. These technologies can include mechanical recycling, where materials like plastic and metal are physically processed, and chemical recycling, which breaks down materials at a molecular level to create new products. Advanced recycling technologies also involve innovations like pyrolysis and gasification, which convert waste into energy or raw materials. These methods help reduce landfill waste, conserve natural resources, and lower greenhouse gas emissions, contributing to a more sustainable environment.
