New method – recycled concrete becomes new concrete ...
2021-2-25 Recycled concrete increases in value “In Sweden, concrete waste is considered low-valued; it simply ends up as landfill or is used as backfilling of roads and the construction of landfills. Concrete waste as aggregates in new concrete production extends the technical life of structural concrete and means closed-loop recycling.

Recycled concrete aggregates - ScienceDirect
2005-2-1 The subject of concrete recycling is regarded as very important in the general attempt for sustainable development in our times. In a parallel manner, it is directly connected with (a) increase of demolition structures past out of performance time, (b) demand for new structures and (c) results––especially in Greece––of destruction by natural phenomena (earthquakes, etc.).

Construction and Demolition Waste Management in
2016-6-17 The recycling rate of CDW in Sweden is considered to pass the EU 70% recycling target when the data collection to prove it becomes more successful. Most of the CDW is mineral waste, which is currently used as aggregate in roads, parking areas or in embankments. The second largest waste flow is wood waste, which is used as fuel in energy production.

Reasons to recycle and reuse concrete
2021-8-4 04-08-2021. When any concrete structure, road, sidewalk or parking lot is destroyed instead of disposing of the demolition waste it should be crushed into high-quality aggregates, creating Recycled concrete aggregate (RCA). The benefit of recycling aggregate includes: Reduce the quantity of debris sent to landfill. Avoid disposal centres fees.
