O.C.O Technology has developed a versatile process that utilises carbon dioxide gas as a resource to treat and valorise a wide range of wastes.

Many wastes react naturally with carbon dioxide. If the conditions are carefully controlled, this natural reaction can be accelerated, taking place in minutes rather than months or years. This results in the formation of calcium carbonate (manufactured limestone).

Technology

The process is a genuine Carbon Capture and Utilisation (CCU) process. During the process, significant volumes of carbon dioxide are permanently captured as stable carbonates.

The process has further benefit in the valorisation of thermal wastes as construction products. At the three commercial facilities in the UK, carbonated thermal wastes are blended with binders and fillers and then pelletised to form a rounded aggregate (M-LS or Manufactured-LimeStone) that has many applications in construction.

The finished M-LS has captured more carbon dioxide than is emitted in its manufacture, resulting in the World’s first carbon negative aggregate.

The O.C.O Technology process has been recognised in a United Nations Environment Report and acknowledged as making "a demonstrable contribution to the developing European circular economy".
