HPQ Fumed Silica Reactor Slashes Co2 Emissions in Fumed Silica Production by Over 50%

MONTREAL, May 24, 2023 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. ("HPQ" or the "Company") (TSX-V: HPQ) (OTCQX: HPQFF) (FRA: O08), a technology company specializing in green engineering processes for silica and silicon material production, is pleased to update shareholders on the significant environmental benefits of the Fumed Silica Reactor ("Reactor") currently being developed by its wholly-owned subsidiary, HPQ Silica Polvere Inc. (HPQ Polvere), in collaboration with technology provider PyroGenesis Canada Inc. (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY) (Pyrogenesis).

HPQ is excited to announce that, based on recent results published, the ground-breaking reactor technology is poised to achieve an outstanding reduction of over 50% in direct CO2 e (CO2   equivalent) emissions associated with fumed silica production, surpassing conventional industry practices.

A cutting-Edge Technology Reducing Direct CO2 Emissions in Fumed Silica Production by Over 50%

Conventional fumed silica manufacturing processes rely on Silicon Metal (Si) as a feedstock, involving complex steps, high energy consumption, hazardous materials, and Hydrogen Chloride Gas (HCI) production as by-product. These processes result in a carbon footprint of 9.5 tonnes (t) CO2 e/t of fumed silica ± 2.5 t CO2 e, with over 60%1 of emissions stemming from the use of silicon metal.

By contrast, the HPQ Polvere Fumed Silica Reactor enables a direct transformation of quartz into fumed silica, eliminating the need for the conventional carbothermic process to convert quartz into silicon metal. This innovation could potentially reduce direct CO2 e emissions associated with fumed silica production by more than 60%, equivalent to a reduction of approximately 5 t CO2 e/t of fumed silica produced2.

"The Fumed Silica Reactor developed by HPQ Silica Polvere Inc. perfectly embodies HPQ commitment to green engineering processes. We are dedicated to developing innovative processes that minimize the environmental footprint while meeting the material demands of the industry, " said Mr. Bernard Tourillon, President and CEO of HPQ Silicon and HPQ Silica Polvere. "This release specifically highlights the direct CO2 emissions reductions achieved by the Reactor and does not encompass the additional substantial indirect environmental benefits. This includes an impressive reduction of at least 86% in energy requirements for fumed silica production. Work to date strongly suggests the potential for HPQ Polvere to develop commercial grade fumed silica with greatly reduced carbon footprints relative to today's commercially available technologies."

Unlocking CO2 Reduction Potential: Exceeding 500,000 Tonnes Per Year (t/y) In Key Markets

The significant CO2 reduction potential of the HPQ Polvere Fumed Silica Reactor is exemplified by the following key markets examples3:

These figures highlight the significant environmental impact that can be achieved by utilizing the HPQ Polvere Fumed Silica Reactor in key markets. Furthermore, there is a potential for substantial per-tonne reduction in carbon taxes in these markets:

These potential reductions in carbon taxes underscore an additional financial advantages and environmental benefits of embracing the HPQ Polvere Fumed Silica Reactor in these markets.

"The reactor also represents a paradigm shift in Fumed Silica production, pushing the boundaries of sustainability and environmental impact," Mr. Tourillon added. "The numbers speak for themselves as we envision a future with cleaner and greener manufacturing processes."
