Gallery: World’s First Carbon Negative Building Block Unveiled in the U...


The Carbon Buster is the world’s first building block to capture more carbon dioxide than is emitted during its manufacturing (14kg per ton). The high-performing masonry product, developed by British company Lignacite, Ltd. in partnership with Carbon8 Aggregates, is made up of more than 50% recycled material – including Carbon8 pellets (which are made of thermal residue from waste to energy plants), water and carbon dioxide. The resulting aggregate is incorporated into the company’s products to create the carbon negative building block.

For its other products Lignacite used sand and gravel combined with recycled materials such as wood shavings, glass and shells, creating products that had a minimal carbon footprint. Through partnership with Carbon8 Aggregates, the company managed to produce a new masonry product that boasts negative carbon content.

The product idea is based on a research carried out at the University of Greenwich’s School of Science, which focused on the reuse of thermal residues from waste to energy plants. By mixing the residue with water and carbon dioxide, the Carbon8’s experts were able to transform the residue material into an environmentally friendly substitute for conventional building aggregates. The company’s carbonation plant was erected in Brandon, Suffolk, next to Lignacite’s masonry plant. Two companies joined forces to manufacture the Carbon Buster block which is made out of carbonated residues, mixed with binders and fillers.

    Me parece muy interesante su aportacion cientifica, a lo cual, leinferencia respecto a la ruta de realizar un nuevo sistema constructivo para la edificacion sostenible es de verdad muy buena aportacion…felicidades!

    Just more greenwash to try to justify “energy from waste” plants, a.k.a. INCINERATORS.
    Burning garbage is still far from an ideal solution.

    This is great. But, what is the cost? Is it prohibitively expensive? And if it’s made from recycled materials, what if the supply dwindles?

    This is excellent, yet calling this the first carbon negative building block ingores many other solutions especially vernacular construction methods such as adobe, strwbale, strawslip, etc.

    Thank you for reporting on the continued quest for more sustainable building solutions.

    “… the world’s first carbon neutral building block…”

    What about hempcrete?!
