National Recycling Award for Carbon8 aggregate

Carbonated aggregate used in world’s first carbon-negative building block wins recycling award

CARBON8 Aggregates’s carbon-negative aggregate, which is used in the Carbon Buster building block from Lignacite, has won the 2013 UK National Recycling Awards for Best Recycled Product.

Masonry products manufacturers Lignacite first launched their carbon-negative building block in May 2013, which is a world first and a British innovation. The block has been developed by the company in partnership with Carbon8 Aggregates, using accelerated carbonation technology.

The Carbon Buster incorporates more than 50% recycled aggregates and combines this with Carbon8’s carbonated aggregates derived from by-products from waste-to-energy plants.

The result is a high-performing masonry product, and the first ever building block which has captured more carbon dioxide than is emitted during its manufacture (minus 14kg of CO2 per tonne).

‘We are delighted that this new carbonated aggregate that we use as a key ingredient in the Carbon Buster block has been recognised as the revolutionary innovation that it is,’ said Lignacite’s chief executive, Giles de Lotbiniere.

‘This aggregate is key to creating structures that will help meet the Government’s zero-carbon buildings target, and build a more sustainable future for us all.’
