Crude zinc ashes, also known as zinc skimmings, are residues left behind in the galvanising bath after the hot-dip galvanising of steel. These ashes appear as a thin layer on the surface of the galvanising bath and are removed after each cycle. Rezinal processes zinc ashes received from various sources, including hot-dip galvanising of construction materials, zinc-coating of wires and pipes, and zinc smelting residues. Our ecological solution ensures that the chain remains closed, converting zinc ashes into valuable raw materials for reuse.
Environmental Impact
By processing zinc ashes, Rezinal contributes to environmental sustainability by keeping the chain closed and minimizing waste. Recycling zinc ashes reduces the need for virgin zinc extraction, conserving natural resources and lowering energy consumption. Additionally, our eco-friendly approach helps reduce greenhouse gas emissions and promotes a circular economy, where valuable materials are reused and repurposed efficiently.
Applications
- Hot-dip galvanising: Hot-dip galvanising is a process that protects steel objects against corrosion by applying a protective zinc coating. After galvanising, zinc ashes are generated and collected for processing by Rezinal. We efficiently convert these ashes into valuable raw materials, ensuring sustainability in the galvanising industry.
- Zinc spraying: In zinc spraying, zinc is applied to iron and steel surfaces to provide a protective layer, prolonging their lifespan. Rezinal processes zinc ash generated during zinc spraying, further contributing to the sustainability of surface protection processes.
- Other types of zinc ashes: Residues from the production of primary zinc metal or other melting processes also generate zinc ashes. Rezinal processes these zinc ashes, maximizing resource utilization and minimizing waste in the zinc-processing industry.
