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 requiring treatment every year. Returned concrete has a high environmental impact on concrete plants and leads to extra operating costs. Current systems for treating returned concrete do not offer a sustainable solution in that they: 1 Have a negative impact...

The pursuit of sustainable development depends on our capacity to guarantee the total the economy, society and the environment. These three elements must never be considered as single, independent entities, but rather analysed within a systemic framework as elements which, together, contribute to the achievement of a common goal. This means that every programmed intervention must take all reciprocal inter-relations into consideration. If a programmed intervention focuses on only one or two of these aspects, a condition of sustainability will not be achieved. In view of these considerations, it...
