Hydro Mechanical Treatment HMT

HMT stands for hydro-mechanical treatment. By means of a washing plant, the environmental quality of the incinerator bottom ash aggregate is verifiably enhanced. The pollution levels are reduced as both the sludge fractions and light organic components are removed. The remaining sandy and coarse fraction is proportionally mixed and provided with an additive. The result is GRANOVA aggregate with significantly improved environmental characteristics, so that the protection of soil and groundwater is ensured.
