Recycling machines are devices or systems that are used to sort, process and dispose of waste. They usually work in several steps to separate, shred and process waste in order to prepare it for reuse or disposal.

Recycling machines are used in various industries, including waste treatment plants, resource recovery, manufacturing and agriculture. They can be used to shred, sort and recycle paper, plastic, metal, glass and other materials, as well as process organic waste such as garden waste and food scraps. Some recycling machines are also specifically designed to process electronic waste (e-waste).

There are different types of recycling machines that are used to process waste. Some examples are:

1. Paper and cardboard recycling machines
   These machines separate paper, cardboard and paperboard packaging (PPK) from other materials and then shred them into smaller pieces. These are then pressed into new paper, cardboard or carton under pressure and heat.
2. Plastic recycling machines
   These machines sort plastic waste according to its different types and then shred it into smaller pieces. The shredded plastic pieces are then processed and turned into new products.
3. Metal recycling machines
   These machines often separate metal waste from other materials using over-belt magnets and then shred it into smaller pieces. The shredded metal parts are then processed and turned into new products.
4. Biomass recycling machines
   These machines process organic waste such as garden waste and food scraps by shredding and then fermenting them. In some cases, waste water is also treated during this process. The result is biogas, which can be used as an energy source.
5. Glass recycling machines
   These machines sort and crush glass waste, which can then be processed into new glass products.
6. Electronic waste recycling machines
   These machines are specially developed for processing electronic waste (e-waste). They separate the different materials and can then process and recycle metals, plastics and other materials.

Each of these machine types has its own technology and mode of operation, which is tailored to the specific requirements of the respective type of waste.
