Description: 

Production of traditional cement blocks for construction consumes a lot of energy and emits a lot of CO2, while using natural raw materials such as drinking water, river sand and gravel.

eCO2blocks creates an alternative – or a complementary material – to cement by producing building blocks made from industrial waste and water which is not fit for drinking. The final product is similar to a conventional cement block, with some differences in colour, density and strength. eCO2blocks is a start-up which began at Universidade Beira Interior (UBI) in Portugal.

Main activity field:

Main results: 
  • Blocks costs about 50% less to manufacture than cement
  • The blocks withstand temperatures of up to 900oC, while cement is limited to 400oC.
