Environmentally friendly production
Instead of that environmentally-unfriendly outcome, innovative U.K. Company Carbon8 Aggregates Ltd. (Carbon8) has come up with a truly green option.
The company uses a patented process known as Accelerated Carbonation
Technology to transform the APCr into a product called C8Agg. This is a carbon negative aggregate that has many uses including in the manufacture of dense and medium-dense masonry blocks.
Tens of thousands of tons of C8Agg is produced annually at two plants that
Carbon8 operates in the U.K. Each site has a number of silos for reception and storage of the incoming residue. The site at Avonmouth, for example, has eight 130 cubic meter silos receiving between seven and eight tanker loads of APCr per day.
Driven by the environmental urgency to both divert landfill and reduce carbon dioxide in the environment, a third site in Leeds is currently being built, with other plants expected to come online in the coming years.
The recipe for C8Agg requires the treatment of a precise mixture of APCr's from a number of sources which vary widely in density, with the beed for relible and accurate inventory control being fundamental to the efficient running of the plant.
