“…Overwhelming majority of works devoted to scale processing describe granulation processes (manufacture of pellets) and briquetting, that really are preparing operations before pyrometallurgical processing [9][10][11][12][13]. Several scientific teams propose to use scale as additive to building materials [14][15][16][17][18]. Some enterprises try to solve the problem of scale processing and utilization via its use for perimeter pavement of domestic roads or as substrate / filling agent in building works; however, it is not always allowable from the point of view of ecological and industrial safety.…”

The main directions of alternative use of scale, a metal-containing waste material from forging and pressing shops at metallurgical enterprises, were suggested and researched within the framework of this work. Scale composition from the processes of heat treatment and forging of steel components from forging and pressing shops at the machine-building plant in the Moscow region was examined. It was established that up to 99 % of scale is presented by magnetic phases of iron oxides, supposedly in the form of Fe 3 O 4 , and alloying components do not practically transit in scale. The technology of sulfuric acid and hydrochloric scale processing with obtain of coagulants is suggested for purification of waste water at galvanic sections or hydrochloric pickling solutions respectively. The technology of scale use as filtrating loading for the processes of purification and neutralization of chromium-containing waste water is proposed. Hugh reducing ability of scale as a reactant for purification of acidic waste water was established in the wide range of initial concentration values of chromium (VI) compounds. Possibility of scale use as Fe-containing additive for pyrometallurgical processing of quartzite-leucoxene, a large-capacity titanium-containing mineral waste, was examined. It was established that chemically active pseudobrookite is the final conversion product; it can be used as raw material for manufacture of wide spectrum of commercial products.

With a rapidly increasing amount of waste, waste management is an extremely important issue. Utilising processes such as combustion and biological processing significantly decreases the accumulation and volume of waste. Despite this, huge volumes of resulting waste that still need to be managed remain. This paper identifies various methods of processing organic waste, discussing both thermal and biological techniques for waste management. Additionally, this paper demonstrates that the end products remaining after processing waste are oftentimes functional for agricultural use. These materials are excellent byproducts used to produce various organic, mineral and organomineral fertilisers. For instance, it appears that the production of fertilisers is the most promising method of utilising fly ash that results from the combustion of waste. In order to minimise the environmental risk of polluting soil with heavy metals, waste, as well as ashes resulting from combustion, must meet the criteria for the limit of contaminants.
