MONTREAL, May 24, 2022 -- PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), a high-tech company (hereinafter referred to as the “Company” or “PyroGenesis”), that designs, develops, manufactures and commercializes advanced plasma processes and sustainable solutions which are geared to reduce greenhouse gases (GHG), is pleased to announce that, further to its press release dated April 20 th , which provided an update on its Aluminum Business offerings, the Company has undertaken a joint evaluation (the “Agreement”) with a major manufacturer (the “Client”), to test PyroGenesis’ zero-emission plasma torches in their scrap remelting and holding furnaces for the aluminum industry. The name of the Client remains anonymous for confidentiality reasons.

This Agreement outlines, amongst other things, the first step being a computational fluid dynamics (CFD) study to gather pre-test data and evaluate plasma for use in furnaces serving the secondary aluminum market: i.e., aluminum producers who re-melt and re-sell scrap and recycled aluminum.

PyroGenesis has already received a purchase order for the CFD study which is well underway, and additional next steps are already being planned.

The Client is one of the largest manufacturers of industrial furnaces around the world, with an almost 100-year legacy, who supplies industrial furnaces and engineering/metallurgical solutions - for virtually all process steps – to the aluminum, steel, and mining industries.

“This Agreement underscores the applicability, and timing, of PyroGenesis’ offerings within the aluminum industry which, incidentally, has now expanded beyond just primary aluminum producers,” said Mr. P. Peter Pascali, CEO and Chair of PyroGenesis. “This is particularly interesting given this Agreement is, once again, with such a prominent manufacturer in the industry.”

“Driven by (i) rising aluminum demand 1 and (ii) the fact that secondary scrap aluminum contributes to the overall aluminum supply at a much lower energy and emissions intensity (up to 95% less carbon footprint compared to primary aluminum production from initial mined ore 2 ), more and more aluminum producers are taking steps to increase scrap metal in their product lines. The sector’s low-emissions claims and targets put significant pressure on ensuring that the process itself (to melt scrap and maintain molten heat) is done with as low a carbon footprint as possible. PyroGenesis’ combustion-less and emissions-free electric plasma torches are a rare technological solution that is immediately identifiable,” continued Mr. Pascali. “As such, we look forward to announcing additional initiatives within this sector of the aluminum industry as negotiations currently taking place bear fruit.”
