Clean tech Greenwich spin-out Carbon8 develops carbon negative building blocks.

Carbon8 Systems, a clean tech spin-out of the University of Greenwich, has succeeded in developing a carbon negative artificial aggregate which can be used to develop environmentally friendly building materials.

The aggregate, C8Agg, captures more carbon dioxide in its material than is produced during its manufacture. With assistance from local building supplies manufacturer Lignacite, Carbon8 has been able to utilise the aggregate in the production of carbon negative bricks.

Colin Hills, director of technology at Carbon8 Aggregate, said: “The UK…
