PyroGenesis` DROSRITE™ toll service has two types of revenue: (i) a traditional toll per ton of processed dross, which extends widely by region and typically amounts to US$450 per tonne, and (ii) a bonus based on increasing the recovery of aluminum, uniquely produced by PyroGenesis` DROSRITE™ technology, usually between 10 and 20%. Since electrolytic copper is superior to electrical conductivity and maneuverability, it is used in a variety of electrical wires and wrought iron and copper alloys. In addition, due to its unique color palette and corrosion resistance, it is often used as a building material. “PyroGenesis` on-site DROSRITE™ toll services address all environmental concerns in the management of Dross at the head,” said Pierre Carabin, Chief Technology Officer and Chief Strategist of PyroGenesis. “Existing technologies continue to offer salt-based processing technologies and address the resulting hazardous waste of saline slag through the development of complex saline slag post-treatment and washing technologies. The result is an unwieldy three-step offer: (i) the hut must cool the slag and transport it off site, losing precious metal; (ii) the slag is then transformed into hazardous and toxic salt-based slag residues and (iii) the saline slag residues, now heavily contaminated, must be transported to a third plant specially designed to: wash the saline slag and transform the material into a non-hazardous material. In contrast, PyroGenesis` patented DROSRITE™ technology is a simple and inexpensive solution, with a high return on investment for the customer. In particular, hot slag is treated on site, in the hut, without hazardous waste of salted slag. Mr. P.

Peter Pascali added: “In addition to this recent agreement, we are actively following other toll agreements for our new multi-billion euro global partner, headquartered in Japan, which we announced in November 2018. Our business development team, along with the senior management of our Japanese partner, recently returned from our first round of on-site customer visits, all of whom wanted to take the next step. This contract, together with other discussions we are having with various stakeholders around the world, should allow us to offer, together with our Japanese partner, an offer of cookie cutters and to quickly introduce our on-site toll activities worldwide. MONTREAL, Feb. 19, 2019 (GLOBE NEWSWIRE) — PyroGenesis Canada Inc.
