Ukraine should mine its mountains of metallurgical slag and ash for road building materials,

the European Business Association recommends in a new, 44-page study. Citing European experiences, the study says that by recycling these byproducts from steel manufacturing, Ukraine will cut industrial waste and cut the mining of sand and gravel. “Stimulating the use of ash and slag materials and rock, in addition to reducing material costs, will improve the state of the environment,” the study says. Six months ago, Ukraine adopted national standards for the use of slag for road beds and surfaces.
