Re-con Zero – Returned concrete with zero impact
The global production of concrete amounts to a total of 10 billion m3/year. Out of this total, approximately 50 million m3 of concrete is never actually used and is returned to the production plant. Considering just 10% of this total as “critical”, meaning not recyclable while fresh, this translates into 5 million m3 of returned concrete requirement treatment every year. Returned concrete has a high environmental impact on concrete plants and leads to extra operating costs.
