We produce green eco concrete

By using new knowledge and technologies we contribute to recycling concrete.


C2CA Technology was established in May 2016 by Delft Enterprises, the Faculty of Civil Engineering and Geosciences of Delft University, and GBN (a 100% Strukton company). The goal is to develop and utilise new, innovative knowledge about concrete recycling. To accomplish this, a process using ADR (Advanced Dry Recovery) technology is used in Hoorn, the Netherlands. Also, a new fine fraction technology is currently being developed.


From 2011 until 2015, several European partners collaborated in doing research about recycling concrete. This project was funded by the European Union’s Seventh Framework Programme. Two partners, TU Delft and GBN, decided to continue developing and start marketing the C2CA technology. The evolution from a European research project into a SME is truly unique.


One of the main environmental challenges in the construction industry, is the need to decrease the bulk transport of building materials in urban environments. Considering this fact, applying more in situ recycling technologies for Construction and Demolition Waste (CDW) could be the key. To achieve this goal, a new low-cost classification technology, called Advanced Dry Recovery (ADR) is being developed.
