As in the case of the thermal zinc-refining sector, reductions in aqueous cadmium emissions were in part achieved by recycling the cadmium-containing wastes to electrolytic zinc/cadmium refineries. In fact, recycling of industrial sludges and solid wastes increased significantly during the 1970s and 1980s for most industrial sectors in the basin.

What is metal recycling? Metal recycling is the process of separating, cleaning, and melting ferrous and non-ferrous scrap to be used again as a raw material for new products. Metal is a material that can be recycled over and over again without degradation of its properties. Besides the ecological benefit of metal recycling, there is also an economic benefit.
