MONTREAL, March 12, 2024 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: O08), a technology company specializing in green engineering of silica and silicon-based materials, is pleased to update shareholders on the advancement of its Fumed Silica Reactor (FSR) Pilot Plant project.

Further to our February 6th, 2024 release, HPQ Silicon’s wholly owned subsidiary, HPQ Silica Polvere Inc. (HPQ Polvere), received notification from its technology provider and equipment supplier, PyroGenesis Canada Inc. (TSX: PYR) (OTCQX: PYRGF) (FRA: 8PY) (PyroGenesis), that all the materials needed for the Fumed Silica Reactor (FSR) Pilot Plant project have been received.


Now that all major equipment’s needed have been received, the 50 tonnes per year (TPY) FSR pilot plant now moves to the final fabrication and assembly phase; with a scheduled commissioning in Q2 2024.

Having successfully achieved the following key milestones:

  • Made commercial grade Fume Silica directly from quartz at lab scale using HPQ FSR technology (May 17th, 2023, release),
  • Attracted the interest of major industry players that signed 3 party NDA’S [1] to test our material characteristics (May 25th, 2023, August 24th, 2023, September 14th, 2023, and October 18th, 2023, releases),
  • Received independent third-party confirmation that we made commercial grade Fume Silica directly from quartz at lab scale using HPQ FRS technology (November 8, 2023, release),
  • Completed an internal technical and economic study that indicated HPQ FSR’s robust potential at commercial scale (January 10th, 2024, release) and
  • Attracted the interest of an industrial group to explore the potential of creating a commercial FSR 1,000 TPT plant joint venture (January 31st, 2024, release).

We are about to start the most exciting part of the project, validating, at a pilot plant scale, our substantial, unique, and proprietary advantages, the ability to manufacture commercial-grade Fumed Silica directly from quartz in one step for significantly less than all traditional manufacturers,” stated Mr. Bernard Tourillon, President and CEO. “With commissioning scheduled to commence in Q2 2024, the time for third parties showing strong interest in our tech to stay on the sideline is getting shorter.”


The table below clearly illustrates the numerous disruptive advantages of HPQ Polvere's Fumed Silica Reactor (FSR) compared to traditional Fumed Silica Manufacturing.

"In emphasizing the significance of the upcoming pilot plant phase,” Mr. Tourillon expressed, “One of the additional advantages is that we fully expect to further validate these numbers and improve them. This underscores our commitment to ongoing refinement and optimization as we move forward in the project.”


The construction of the FSR pilot plant is set to take place in a dedicated space within PyroGenesis’ facilities, featuring tailor-made infrastructure to address the pilot plant’s distinctive ventilation, safety, and access needs. An allocated 4,000 sq ft facility, with a height allowance of 30 feet, has been designated to accommodate the pilot plant, which boasts an approximate layout footprint of 50ft by 30ft.

“We are rapidly moving forward with the fumed silica reactor pilot plant construction, as we recognize that numerous industries will benefit from what we believe is a truly innovative approach to producing one of the most in-demand materials”, said Mr. P. Peter Pascali, CEO and President of PyroGenesis. “Conventional fumed silica processes, which rely on silicon metal (Si) as raw material, not only have a significant carbon footprint of around 9.5 tonnes of CO2 equivalent per tonne of fumed silica, but also present complex process challenges which include, but are not limited to, using hazardous materials.[8] The technology developed by PyroGenesis for HPQ Polvere is designed to offer significant economic and environmental advantages over conventional manufacturers – improving profitability, but also reducing the environmental footprint and reducing the harmful chemicals associated with traditional fumed silica production.”

[2] Traditional Fumed Silica manufacturing involves a complex three-step process. Step 1: Conversion of Quartz to Silicon Metal (Si), with an average Capex of around US$9.38 per kilogram of annual capacity (for reference, the PCC BakkiSilicon Plant in Iceland cost US$300 million for an annual capacity of 32,000 tonnes). Step 2: Conversion of Si to Silicon Tetrachloride (SiCl4), with an average Capex of approximately US$125.00 per kilogram of annual capacity (e.g., Wacker Chemie AG Polysilicon's US production plant cost US$2.5 billion for an annual capacity of 20,000 tonnes). Step 3: Burning Silicon Tetrachloride (SiCl4) with Hydrogen and Oxygen to produce Fumed Silica (SiO2), incurring an average Capex of around US$11.54 per kilogram of annual capacity (Wacker Chemie AG's US Fumed Silica plant cost US$150 million for an annual capacity of 20,000 tonnes). The combined Capex for these three steps averages at US$145.92 per kilogram of annual capacity. According to a rough order of magnitude study by PyroGenesis, our one-step process for making Fumed Silica is estimated to have an average Capex per kilogram of annual capacity between US$9.00 and US$10.00, which is approximately 93% less than traditional processes.

[5] Average EBITDA margins of 20% are derived from two sources, with Link #1 leading to Source #1 and Link #2 leading to Source #2 (Specialty Additives division). Management has calculated the EBITDA margins for the Fumed Silica Reactor (FSR) based on data derived from third party sources and publicly available information. These figures will be updated upon completion of the pilot testing phase. The 5% range in HPQ Polvere's EBITDA margins considers PyroGenesis' option to convert its 10% royalties into a 50% ownership stake in HPQ Polvere's remaining equity.
