Extracting precious zinc from waste ash
Incineration of solid waste produces millions of tonnes of waste fly ash in Europe each year, that most commonly ends up in landfill. But this ash often contains significant amounts of precious metals, such as zinc. A unique method developed by researchers at Chalmers University of Technology, Sweden, can now help extract these precious metals, potentially leading to reductions in environmental pollution, landfill and transport.During waste incineration, the released flue gases are purified and the small particles present are separated, leading to the formation of fly ash. This
New research facility for large-scale demonstration project. According to the World Wide Fund for Nature, the Baltic Sea is one of the most contaminated inland seas in the world. Eutrophication, overfishing, increased shipping and emissions have all contributed to turn the Baltic into a sea in crisis. The Baltic cod is uniquely adapted to survive in the specific habitat of this inland sea. It is an apex predator that plays a key role in the food web.Based on a pilot study that AFRY conducted in spring 2020, the company strengthened its trust and was given the responsibility to drive the
