Recycling rubble can help rebuild Syria faster, scientists show

Tests show recycled concrete could safely be used in new buildings in war- and quake-stricken country

Concrete rubble from destroyed buildings in Syria can be safely recycled into new concrete, scientists have shown, which will make the rebuilding of the war-hit country faster, cheaper and greener.

Syria, which was also hit by a huge earthquake in February, has a vast amount of concrete rubble, estimated at 40m tonnes. The key barrier to recycling this waste is ensuring that the new concrete is as strong and safe as conventional concrete.
