How does recycling work?

In recycling, the term “utilisation” has different meanings. It is often used to refer to the use of waste to generate energy through incineration. It is particularly common in the following three areas:

• Thermal utilisation: waste is incinerated using high temperatures and the resulting heat energy is used to generate electricity.
• Biological utilisation: Waste is decomposed by microorganisms to produce biogas.
• Chemical recycling: Waste is chemically treated to convert it into simpler components that can be used as raw materials for new products.
