Paebbl scales up carbon-capture concrete tech

Using a low-energy patented process, Paebbl’s reactors convert CO2 into CO3, adding water and ​​ground silicate rocks to produce a solid carbonate-based material. For every tonne of CO2 stored, the process generates up to two-and-half tonnes of material. According to the company, the silica-enriched mineral can be used as an inert industrial filler or as an ingredient in building materials, reducing the CO2 footprint of concrete by as much as 70 per cent. 

Having only recently taken the technology beyond the lab, Paebbl has now commissioned a new 500L batch production unit called ‘Obelix’. The company claims that Obelix has scaled Paebbl’s CO2 processing capacity 100x in less than six months, with the reactor capable of delivering up to 100 tonnes of carbon-storing materials annually.

“With over two decades of research going into our technology, Obelix is a clear statement of intent that we are committed to meeting the strong industry demand for our products,” said Andreas Saari, co-founder and co-CEO at Paebbl.
