Abstract

Carbon8 Systems is a university spin-out company developing and applying accelerated
carbonation for the commercial production of aggregates from waste. Hazardous wastes can
be converted into construction products that meet the regulatory requirements for ‘end of
waste’ using carbonation. hen the accelerated carbonation process is applied to municipal
solid waste incineration (MSWI) air pollution control residues (APCr), the ash is solidified and
stabilised in carbonate-cemented pellets. The pelletised products have mechanical and
chemical properties that make them suitable for use in concrete blocks. In early 2012,
following the success of a series of pilot and full-scale trials, a full scale carbonation plant was
built and commissioned at Brandon in Suffolk, UK. This plant is the first of its kind in the world.
The aggregate plant has now been operating for about a year and is producing a consistent
product. Continued monitoring of the incoming APCr, and the outgoing aggregate product has
dramatically increased the knowledge of processing this troublesome material. In addition to
rigorous independent third party and in-house testing, the physical and chemical properties of
the product are routinely examined to meet quality control criteria, and to ensure compliance
with the ‘end-of-waste’ status approved by the UK Environment Agency.
