Concrete recycling

Crushed concrete free of contaminants can be used as raw material (sometimes mixed with natural aggregate) to make new concrete. Wellgraded and aesthetically pleasing materials can be used as landscaping stone and mulch. Wire gabions (cages), can be filled with crushed concrete and stacked as retaining walls or privacy walls (instead of fencing).
