MONTREAL - PyroGenesis Canada Inc., an environmental solutions company that designs, develops and manufactures plasma waste-to-energy systems and plasma torch products, has filed for patent protection for its energy efficient, salt-free recovery of metal from zinc and aluminum dross.
Current practices often require zinc and aluminum smelters to ship their dross residue to a third party for expensive treatment and metal recovery. PyroGenesis' technology, DrosRiteTM Plus, treats hot dross at the smelter, resulting in improved metal recovery and a significant reduction in greenhouse gas generation, compared to shipping it off site.
DrosRite was developed with the support of Canmet's industrial energy R&D program. It promises low capital costs, up to a 10% boost in metal recovery, energy savings, and low operating costs. The technology has been demonstrated at several aluminum and zinc smelters in North America and Europe.
A mobile demonstration unit is available for trials at individual smelters. Contact PyroGenesis Canada by calling 514-937-0002, emailing plasma@pyrogenesis.com or visiting PyroGenesis.com.
