Mercury is a priority pollutant
because of its extreme toxicity, global atmospheric transport and
accumulation in the food chain. Its removal from current industrial
emissions as well as from previously polluted sites is therefore
mandatory. A unique biotechnological process for removal of mercury from wastewater based on the enzymatic transformation reactions of live mercury resistant bacteria has been developed at GBF,
tested for 8 months at a German chloralkali plant and operated at a
Czech chloralkali electrolysis factory in full scale for more than two
years. This new technology is proven to be efficient, robust,
environmentally friendly and cost effective. The aim of the specific
support action BIOMERCURY is to
- evaluate the applicability of the microbe based technology for clean-up of contaminated environments worldwide;
- monitor the longterm performance of the first industrial microbe based mercury removal plant,
- compare costs, safety and efficiency of the biotechnological approach with traditional methods;
- transfer knowledge into developing countries where the problems are most urgent;
- exchange information with US agencies.
These goals shall be approached by an international consortium which will first conduct case studies on hot spots of pollution as well as on current mercury emitting industries, taking into account technology offers. On this basis, integrated engineering
concepts will be developed. They will be communicated to governments
and International Agencies with the aim of implementing demonstration
or remediation projects.
