Sweden: Ovako has signed a contract with NCC to supply steel slag to be used as ballast in asphalt. As part of the contract, NCC will buy 50,000t/yr for the first three years and then 85,000t/yr. The road surface should be quieter, more durable and more sustainable, according to NCC-run tests in Borlänge.
