LEACHABLE POLLUTANTS OF SECONDARY RAW MATERIALS

LEACHABLE POLLUTANTS OF SECONDARY RAW MATERIALS

abstract

Czech

Ever-increasing production of waste materials has become a serious economic and political worldwide problem. New approaches are required in almost all industrial procedures to reduce current trends of waste formation and to create new methods of ecological and economic recovery or disposal of waste. How to use these materials as a substitute for primary raw materials need to be learned, mainly because it is necessary to limit environmental damage by mining and by establishing of landfills. As far as the environment is concerned, the disposal of fly ash should not be regarded as a sustainable management strategy. Fly ash and the slag as secondary raw materials are considered as hazardous materials because of their high content of heavy metals such as lead, arsenic, barium etc. That is why both of them should be well treated to reduce their damage to the environment.
