Transforming waste into resource
With the environmental recycling of zinc from electric arc furnace dust
Zinc and scrap steel recycling
Scrap steel is often recycled in an electric arc furnace. During this process, zinc from galvanized coatings evaporates into a dust. This dust is normally landfilled or treated with a Waelz kiln. Waelz kilns use coal to reduce and evaporate the zinc, forming a low-purity zinc oxide product known as Waelz oxide. This process produces an iron slag waste stream, that at best can be used as aggregate.
Zincovery’s process is a novel technology, which relies on clean electricity rather than polluting coal to recover zinc within the EAF dust.
Zincovery: The new way
Zincovery is re-imagining the recycling of EAF dust, with the aim to reduce metallic waste and harmful emissions. Our process will produce high purity zinc metal and a valuable iron oxide product, extracting greater value from EAF dust thus turning waste into a valuable resource.
Technological development
We are currently building a pilot plant, and taking expressions of interest for practicing the technology at demonstration plant scale.
