Production of Precast Concrete - Sustainable Precast

Solid waste from precast plants is very low, about 2.5% of the mass of concrete used in the production. About 95% of this waste can be further beneficially reused through crushing and recycling of hardened concrete, leaving approximately 3 kg/m³ of actual

Recycled Aggregates

The simple act of recycling the concrete reduces the amount of material that must be landfilled. The concrete itself becomes aggregate and any embedded metals can be removed and recycled as well. As space for landfills becomes premium, this not only helps
