100 % Circular
concrete
C2CA (Concrete to Cement & Aggregates) is a pioneering company that upcycles waste concrete into sustainable building materials, founded in 2016 by the technical university of Delft and GBN.
Mission
Our mission is to create a completely closed concrete loop where end-of-life (EoL) concrete is 100% upcycled into drop-in sustainable materials.
C2CA's technology aims to solve the three biggest drawbacks of concrete.
Concrete is one of the most widely used building materials worldwide, but with it, concrete is also among the largest sources of CO2 emissions. Cement causes 8% of global CO2 emissions.
High emissions, especially CO2 emissions, which have a big impact on climate change
Scarcity of raw materials, in parts of the world raw materials such as sand for use in concrete are scarce and extracting them results in more and more vulnerable nature being destroyed
Huge quantities of rubble are left behind when concrete structures reach the end of their life and without a good method of recycling, these rubble streams end up in landfill and large quantities of raw materials are lost.
