Use concrete block made with recycled material
Recycling industrial byproducts saves space in local landfills
Concrete masonry units (CMUs), also known as concrete blocks, that contain a variety of industrial byproducts are now available. Recycled material includes slag, cinders or bottom ash, and ground waste glass and concrete. Using this kind of block means less mining and crushing of stone as well as reduced load on landfills. However, most plants that make block don't publicize their formulas, so it may take some digging to find out what materials are being used.
