Helping demolition companies capture CO2 - Sika - C2V - CO2 to Value In fact - CLIMAX
Specialty chemicals firm Sika has developed ReCO2ver, a process which produces limestone, sand and gravel from the combination of concrete and CO2 with an additive developed by the supplier.
The process enables demolition companies to completely recycle used concrete, and it stores captured CO2 at 60 kg/t of crushed concrete. The materials produced can be used as aggregates to make concrete of comparable strength to newly produced concrete.
About 2 billion tons of construction & demolition waste is generated every year globally, so that presents a total potential of 120 million tons of CO2 captured through this process, and solving the headache of what to do with the demolition waste ,and perhaps some additional revenues to the construction or demolition companies.
Seems to tick all the boxes, this invention, doesn't it?
