Recycling is a process in which waste and waste materials are collected, sorted and processed in order to transform them into new materials or products. This can include both the reuse of materials and the utilisation of waste materials as raw materials for the manufacture of new products. Recycling has both environmental and economic benefits. It reduces dependence on natural resources and protects the environment in many ways. In addition, recycling can also save energy and reduce greenhouse gas emissions. Some examples of materials that can be recycled are paper, glass, metal, plastic and biomass.

It is important to note that each type of waste also requires a different type of recycling and a method that works well for one material cannot automatically be applied to another material. It is also important to note that recycling is not always the best solution for the utilisation of waste. Often, combinations of recovery methods are used.
