The plants provide a highly-niche service, extracting metals and aggregate from the energy-producing waste facilities.

The waste facilities first burn household and wholesale waste to produce renewable energy. The residue from that process is then recycled further, using processing plants constructed nearby.

The materials extracted include precious metals, such as gold and silver, ferrous metals such as steel and iron, and non-ferrous metals such as copper, lead, tin and zinc. The aggregate extracted can be used in construction, such as in foundations for buildings, roads and pavements.
