Inactivation of toxic metals from waste galvanic sludge by other hazardous waste

Abstract

The paper presents the process of inactivation of toxic metals from waste galvanic sludge by other waste materials such as waste sludge from the technological process of iron production, waste ash from thermal power plants, zeolite and waste cathode glass. Inactivation is performed by the sintering process at high temperatures. The obtained sintered product has such a structure that where toxic metals present in it can not be started even under critical conditions. Furthermore, such a product can have a usevalue and the risk of environmental pollution is reduced to a minimum.
