Carbonless building blocks set to make construction greener
Carbon-free building blocks are set to revolutionise the construction industry, providing a green alternative to traditional building materials. The blocks are produced by British company Carbon8 using technology developed by the University of Greenwich.
Carbon dioxide gas and industrial by-products are mixed to create a “carbon negative aggregate”, of which 36,000 tons are produced each year. This is then processed by masonry manufacturer Lignacite to produce the ‘Carbon Buster’ block, the first of its type to encapsulate more CO2 than is produced during its manufacture.
“The UK government has targets for sustainable housing and wants new builds to be carbon neutral by 2016. This will be the university’s contribution to that initiative.” said Dr Colin Hills, a Reader at the university and Director of Technology at Carbon8. “We want to apply the technology to different waste streams to make more building materials that are carbon negative, including some new and exciting products.”
