Integrated assessment of the use of recycled concrete ...

Feb 10, 2018  1. Introduction. Concrete as a widely used building material produces a large amount of waste, which has the potential for recycling and reuse. With that, closed-loop recycling of concrete has been widely discussed in the last decades as a means of dealing with concrete waste (CW) as a bulk waste stream as well as conserving raw material used to produce fresh concrete.

Up to 70% of environmental impact could be reduced by substituting natural concrete with recycled concrete (Knoeri et al., 2013).
