With gas-fired furnaces responsible for much of the scope 1 emissions of secondary aluminum production, aluminum companies have been searching for solutions that can help in the decarbonization efforts of aluminum remelting and cast houses. The Company has two potential solutions: (i) the retro-fitting of plasma torches in existing remelting and cast house furnaces that currently use other forms of heating, such as natural gas; (ii) the manufacturing and sale of a PyroGenesis produced furnace based off the Company's existing Drosrite metal recovery furnace design, which has been in use commercially for several years. As mentioned in previous Outlooks, the Company has been working with different companies over the past few years towards these goals. During Q4 2024, the first project under a letter of intent (LOI) previously signed with Constellium progressed to advanced negotiations, and a near-term announcement regarding this project is anticipated.
