Incineration ash and disposal

Chromates in ash, boiler deposits and old insulation

Hexavalent chromium(VI) compounds, including calcium chromate, are not only carcinogenic but also hazardous to the environment, with long-term consequences for water bodies (H410).

Incineration ash

Chromates in ash and boiler deposits

In waste incineration, chromium(VI) compounds form in particular when the plant is shut down and the grate and ash residues cool with access to oxygen, and in direct desulphurisation with calcium hydroxide or limestone powder. Incineration ash containing chromium(VI) is a field of its own, with its own questions on sampling, classification and disposal route.

The scope covers the ash residues remaining on the grate, bottom ash, furnace residues and deposits on chromium-alloyed hot parts, in addition to fly, filter and boiler ash.

Disposal

Transport and disposal

Disposal of chromate-contaminated insulation from a CHP plant

Because of their toxicity, chromate-contaminated old insulation and thus the removed (textile) insulation elements are hazardous waste requiring labelling, which must be transported and disposed of in a special manner.

Article 5(5)(m) of Directive 2004/37/EC requires the collection, storage and removal of the waste to be ensured, among other things through hermetically sealable and clearly labelled containers. In Germany the mixing ban under section 9a(1) of the Circular Economy Act (KrWG) applies in addition.

The Effinowicz Group offers controlled waste management in Germany, Austria, Switzerland, Liechtenstein and Italy, in particular for the disposal of chromate-contaminated insulation waste from CHP plants and other power-generating plants.
