MONTREAL, Nov. 09, 2023 (GLOBE NEWSWIRE) -- PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), a high-tech company (the “Company” or “PyroGenesis”) that designs, develops, manufactures and commercializes advanced plasma processes and sustainable solutions which are geared to reduce greenhouse gases (GHG) and address environmental pollutants, is pleased to confirm, further to HPQ Silicon Inc’s (“HPQ” or the “Client”) press release dated November 8, 2023 and the Company’s news release dated October 3, 2023, that an independent structural and chemical analysis of fumed silica, produced in conjunction with HPQ Silica Polvere Inc. (“HPQ Polvere”), a wholly owned subsidiary of HPQ, has been successfully performed.

Separately, the Company announces that production of the fumed silica pilot plant is underway, which is intended to be in operation in Q2 of 2024.

The Fumed Silica Reactor (“FSR”), a plasma-based process, converts quartz into fumed silica (also known as Pyrogenic Silica) in a single and eco-friendly step. By eliminating the use of harmful chemicals generated by conventional methods the groundbreaking FSR approach, if successful, will help contribute to the repatriation of silica production to North America.

In collaboration with HPQ Polvere, PyroGenesis confirms that a third-party laboratory at McGill University has validated the commercial quality of the material, highlighting its (i) hydrophilic nature, (ii) high surface area of 135-185 m2/g, and (iii) thickening efficiency characteristics, all of which are pivotal for its commercial applications. The detailed characteristics resulting from the tests can be found in the Technical Data Sheet generated by McGill University (refer to HPQ’s press release for more information).

In addition to this analysis, the latest testing on the material produced with the FSR has demonstrated that HPQ’s proprietary FSR technology as developed by PyroGenesis not only addresses the increasing market demand but also offers substantial benefits in terms of energy efficiency and reduced environmental impact. The test results indicate an expected reduction in energy consumption for the production of fumed silica using FSR. Theoretical estimates suggest a notable reduction in energy consumption ranging from 87.5% to 90% compared to conventional processes while CO2 eq. emissions can be reduced by 84% to 88% compared to conventional processes.
