摘要
The big amounts of ultrafine limestone waste are stored on large areas, constituting a permanent source of pollution for the surrounding areas due to fine limestone dust moved by the air currents, groundwater contamination in the area and sealing productive surfaces where they are stored. This unconventional technology enables the simultaneous obtaining of metallurgical lime and carbon dioxide of advanced purity at much lower costs in a highly productive unconventional plant, designed, developed and implemented in SC AGROMEC S.A. BORCEA Calarasi county, front the raw material in the waste dumps of the metallurgical and chemical companies in the area. The proposed technology capitalizes on the real economic potential of land where the limes-tone waste dumps are, creates an ecological climate for the surrounding areas. At the same lime, some materials extensively demanded on the market can be obtained out of wastage by using this technology. Other environmental benefits that this technology provides are related to emissions of carbon dioxide in the atmosphere which are much more reduced compared to the ones resulted from conventional technologies.
