The collection, sorting and processing of disposed materials for use in other manufacturing processes.
There are two types of recycling:
The recycling process is different for each material and location. Some materials require additional processing (i.e. cleaning, refining, etc.) than others. Additionally, some materials downgrade in quality or material integrity with each life, limiting the number of times they can recycled.
In many places around the world – including those with formalized waste management infrastructure – there is an “informal sector” of recyclers that capture valuable disposed materials and reintroduce them into the economy.
