MERCURY RECYCLING

Alchema have established a separate company, Quicksilver Recovery Services Limited, which offers a comprensive service for the removal of mercury from mercury contaminated waste from a variety of sources including:

• The ChlorAlkali industry
• Fluorescent lamp powders— for which Sustainalite accreditation is held
• Spent carbon filtration media associated with the natural gas industry
• Other industry by-products and site contaminations

The process has a capacity to handle tonne quantities in a batch process (although part-loads can be handled also ) and is based on the breakdown of mercury compounds into metallic mercury followed by vacuum distillation to leave a residual ash which meets the current requirements for landfill and a mercury fraction typically 99.99% pure.

This operation has been developed in direct response to environmental legislation restricting the land disposal of mercury wastes . The process is recognised as Best Environmental Practice by the Environment Agency and carries full IPPC authorisation.
