  • Characteristic of this type of Waste is the fact that it is considered a secondary product of each large-scale process occur in relatively small quantities and therefore predominantly in containers (usually 200 I-drums, maximum silo vehicle) be handled. The majority of these bulk goods must be due to their Degree of contamination can be disposed of thermally (by burning or gasification).
  • the bulk goods are usually placed in a storage bunker Waste treatment plant emptied and with others in the storage bunker Waste into the respective incinerator via a gripper (e.g. rotary tube or grate firing). That is only with great technical effort Occurrence of dust-like emissions when emptying the containers in the Storage bunker and the transfer of the bulk goods into the incinerator to avoid.
