HPQ plans to start commercial production of fumed silica using its pilot plant in Q4 2025, becoming Canada’s first domestic supplier
MONTREAL, Canada — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: 8PY1), a technology company specializing in green engineering processes, would like to inform shareholder that recently announced tariffs and resulting counter-tariffs on critical feedstock including fumed silica has NO impact on discussions with parties under LOI and other NDAs interested in our Fumed Silica material and technologies. Also, the Company would like to add that it intends to start commercial production of fumed silica using its pilot plant this year.
HPQ, through its subsidiary HPQ Silica Polvere Inc. (HSPI) [1], is progressing as planned with the development of its Fumed Silica Reactor (FSR) system. Following the successful production of its first batch in late February 2025, the pilot plant is now optimizing operations to increase throughput from 20–30 kg per batch to over 480 kg per day. During this phase, the fumed silica produced will undergo internal testing, with samples sent to parties under LOI (as per the July 9, 2024, release) and other NDAs.
By Q4 2025, HSPI will begin commercial production of fumed silica using its pilot-scale FSR system, making it Canada’s first domestic producer of fumed silica. With escalating U.S. tariff threats and potential countermeasures, the timing is critical, as these trade policies are expected to disrupt supply chains and increase the cost of imported materials.
“Fumed silica is used in thousands of everyday products, yet Canada has no domestic production, leaving Canadian manufacturers vulnerable to unpredictable trade policies that could swiftly drive prices up. As a result, prices are expected to rise by at least 25%, squeezing businesses and limiting growth,” said Bernard Tourillon, President & CEO of HPQ Silicon and HPQ Silica Polvere. “HPQ’s Fumed Silica Reactor technology has the potential to change that. Our goal is to use the pilot plant to begin commercial fumed silica production in Canada in Q4 2025. At the same time, we will lay the groundwork to scale up production and establish, over the next few years, a reliable, nationally beneficial supply, thereby reducing reliance on U.S. and other fumed silica imports.”
FUMED SILICA: A HIGH-VALUE MATERIAL CAUGHT IN A TRADE WAR
Fumed silica is a high-performance industrial material used in applications ranging from cosmetics and paints to lithium-ion batteries, adhesives, and reinforced polymers. Its high surface area, lightweight structure, and ability to enhance mechanical strength, viscosity, and stability make it indispensable across multiple sectors.
The global fumed silica market valued at approximately US $2.0 billion in 2024 and is projected to grow to over US $3.4 billion by 2034[2], driven by increasing demand for high-performance materials in renewable energy, electric vehicles, and advanced coatings. The US and Canadian fumed silica market is valued at approximately US $411 million in 2024 and is projected to grow to over US $587 million by 2034[3].
High capital and operational costs, along with environmental challenges tied to traditional fumed silica manufacturing, have left Canada without domestic production capacity. As a result, local manufacturers relying on this critical feedstock must import 20,000 to 24,000 tonnes (t) annually—primarily from U.S. suppliers—at an average yearly cost of approximately US $200 million [4]. With new tariffs and counter-tariffs being enacted, the cost of imported fumed silica is set to rise by 25%, significantly impacting key Canadian industries such as automotive, construction, personal care, pharmaceuticals, and renewable energy.
HPQ’S FUMED SILICA REACTOR: A PATHWAY TO SUPPLY INDEPENDENCE FOR CANADIAN INDUSTRY
HPQ Silicon, through its subsidiary HPQ Silica Polvere Inc. (HSPI) [1], is developing a low-Capex, low-Opex plasma-based fumed silica production technology in collaboration with PyroGenesis Canada Inc. Unlike traditional multi-step production methods, which typically require between 100 and 120 kWh per kg of fumed silica [5], HSPI’s one-step, energy-efficient process consumes only 8 to 12 kWh per kg [6]. This significant reduction in energy use lowers operating cost and carbon emissions while maintaining superior product quality.
STRATEGIC ADVANTAGES: A SCALABLE, COST-EFFECTIVE ALTERNATIVE UNDERGOING PILOT-SCALE VALIDATION
Two weeks ago, the HSPI pilot plant successfully produced its first batch of material, marking a major milestone in the commercialization of its technology (February 27, 2025, release). As a 20-fold scale-up from previous lab tests, the pilot plant demonstrated its ability to replicate, at industrial scale, the visually morphological characteristics consistent with those observed in lab-scale fumed silica production.
Following the successful first pilot-scale tests, HSPI is now focused on optimizing batch and semi-continuous fumed silica production. Ongoing efforts aim to increase throughput from 20–30 kg per batch to over 480 kg per day while producing commercial grade materials with surface areas ranging from 150 to 300 m²/g. The overarching goal is to achieve full-capacity operations, enabling multiple daily production cycles and delivering commercial-quality material. With an expected 20 hours of daily operation, the system is projected to produce approximately 161 kilograms per day, equivalent to an annual output of 50,000 kilograms (50 TPY).
By Q4 2025, the fully paid pilot-scale FSR system, will start delivering high-performance fumed silica, providing buyers with a cleaner, more efficient and Canadian alternative to legacy production methods.
HSPI’s FSR design enables a modular, scalable approach to fumed silica production, based on increasing the FSR capability designs by a 20-fold scale up of the pilot system to an initial production target of at least 1,000 metric tons per year FRS reactors. Once the first system is operational in the coming years, the goal will become building multiple Fumed Silica Reactors to have the capacity to meet Canada’s full market demand of 20,000 to 24,000 metric tons annually.
“This is not just about mitigating tariffs,” added Tourillon. “This is about using Canadian know-how to create a more resilient independent supply chain for critical materials. Over time HSPI’s Fumed Silica Reactor could ensures that Canadian manufacturers are no longer at the mercy of U.S. trade policies. We are pioneering a technology that makes Canada self-sufficient in a high-value material while enhancing our global competitiveness.”
