Environmental measures implemented at metallurgical combines can be made more effective by taking an integrated approach that includes not only the recultivation of slag dumps but also recycling of the slag. Such an approach offers the following benefits to the metallurgical plant: the area of land occupied by dumps is decreased; payments for lease of the land and expenditures on transport of the slag to the dumps are both reduced; the environmental situation is improved in and around the dump; useful components of the slag are recovered and products that are used in other industries are obtained. The cost-effectiveness of recultivating and recycling slag dumps is 2.7 rubles/ruble.
