Using recycled rubble to help rebuild Syria
Researchers from Syria, the UK, and Turkey have shown that rubble from destroyed buildings in Syria can be safely recycled into new concrete. Recycling the rubble, estimated at 40 million tonnes, will make the rebuilding of the war-hit country faster, cheaper, and greener. The key barrier to recycling this waste was ensuring that the new concrete was as strong and safe as conventional concrete. Research has shown that using recycled concrete to replace half of the aggregate in new concrete is safe. Recycled concrete has been produced before in other places, but testing is required in each region because of local differences in how the concrete is made. Learn more.
