Method for the recycling of fire-extinguishing powder for fire class BC

摘要

The invention relates to a process for the utilization of fire-fighting powder of fire class BC, which consists essentially of alkali metal bicarbonate by being used in thermal metallurgy in the processing of non-ferrous metal raw materials to lower the melting point of the slag instead of technical soda. This eliminates costly disposal routes, the It. Circular Economy and Waste Act for this previously declared as waste BC fire extinguishing powder, which comes from replaced fire extinguishers, were necessary. This achieves efficient, environmentally friendly recycling instead of expensive disposal / destruction of BC powder.
