Zero liquid discharge (ZLD) is a waste management technique which transforms liquid waste streams from industrial plants into clean water, which can be reused in the process, and a minimal amount of solid residue, which often include valuable by-products. It is particularly useful for industries producing complex wastes which are difficult to treat using traditional techniques.
One such industry is leather processing and tanning where animal skins are transferred into high quality fabric for use in footwear, upholstery, car interiors and other goods. Based in Salinas near Alicante, Boxcapiel is one of Spain’s leading leather producers, processing skins from a range of species into high quality leather for a wide variety of end uses.
