Important Achievement in Silicon Production Process for HPQ Silicon Using PyroGenesis’ PUREVAP Quartz Reduction Reactor

MONTREAL, June 01, 2023 (GLOBE NEWSWIRE) -- PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), a TSX30® and a Deloitte Canada Clean Technology Fast 50TM 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), confirms that, as announced earlier today by HPQ Silicon (“HPQ”), the PUREVAPTM Quartz Reduction Reactor (QRR) designed and built by PyroGenesis achieved successful laboratory validation of quartz to high-purity 3N+ silicon in one step.

As noted in HPQ’s news release, the results of an analysis of recent test samples from PyroGenesis’ PUREVAP QRR process carried out by Balazs NanoAnalysis (a division of Air Liquide Electronics), a global high-tech analytical laboratory, confirmed that the PUREVAP QRR produced silicon from quartz in a single step with a purity exceeding 3N+ (99.92%).

“We are pleased to confirm the test results announced earlier today by HPQ”, said Mr. P. Peter Pascali, CEO and President of PyroGenesis. “Collaboratively with HPQ, we have been working towards this goal for quite some time, and now with these independent test results our shared goal of creating a process that simplifies and optimizes the production of high purity silicon has been achieved.”

“The implications of a one-step process in the manufacturing of high purity silicon direct from quartz is significant, both from a cost benefit perspective as well as from a critical mineral optimization perspective,” continued Mr. Pascali. “This presents PyroGenesis with a unique and exciting commercial opportunity highlighted by (i) the strategic investment we have in HPQ, (ii) the possibility that HPQ will require additional PUREVAP QRR systems as a result of these findings, and last but not least (iii) our 10% royalty payment on HPQ’s eventual sales of the improved silicon.”

While the results of the analysis are highly encouraging, there is no timeline in terms of when HPQ will be in a position to produce the improved silicon on a large commercial scale. Working with PyroGenesis, HPQ will now carry out final adjustments, smaller tests, and a subsequent engineering study to determine the profitability of producing the improved silicon on a larger scale. Subject to this additional testing and planning, HPQ will then determine the number of PUREVAP QRR systems required for the construction of a full commercial plant. As noted previously, HPQ believes that, based on what is known today, at least two PUREVAP QRR systems, with each reactor capable of producing 2,500 MT of high-purity silicon per year, would be required. PyroGenesis and HPQ have estimated the cost of each PUREVAP QRR system to be at least $20 million.

PyroGenesis’ involvement in the development of high-purity silicon from quartz is part of PyroGenesis’ three-tiered solution ecosystem that aligns with economic drivers that are key to global heavy industry. High-purity silicon is part of PyroGenesis’ Commodity Security & Optimization tier, where the recovery of viable metals, and the optimization of production to increase output, helps to maximize raw materials and improve the availability of critical minerals. Silicon has been identified as a critical mineral by many governments worldwide.

About HPQ Silicon

HPQ Silicon Inc. (TSX-V: HPQ) is a Quebec-based innovative silicon solutions company that offers innovative silica (SiO2), silicon (Si) based solutions and is developing a unique portfolio of high value-added silicon (Si) products sought after by battery and electric vehicle manufacturers.

Silicon (Si), also known as silicon metal, is one of today’s key strategic materials needed for the decarbonization of the economy and the Renewable Energy Revolution (“RER”). However, silicon does not exist in its pure state and must be extracted from quartz (SiO2) in what has historically been a capital and energy-intensive process.

With PyroGenesis, HPQ is developing:

  1. the PUREVAP™ “Quartz Reduction Reactors” (QRR), an innovative process (patent pending), which will permit the one-step transformation of quartz (SiO2) into high purity silicon (Si) at reduced costs, energy input, and carbon footprint that will propagate its considerable renewable energy potential.

  2. Through its 100% owned subsidiary, HPQ NANO Silicon Powders Inc., the PUREVAP™ Nano Silicon Reactor (NSiR) is a new proprietary process that can use material produced by the QRR as feedstock, to make a wide range of nano/micro spherical powders of different sizes and nanowires.

  3. Through its second 100% owned subsidiary, HPQ Silica POLVERE Inc., HPQ is developing a new plasma-based process that will allows a direct quartz to fumed silica transformation, removing the usage of hazardous chemical in the making of fumed silica and eliminating the Hydrogen Chloride Gas (HCI) associated with its manufacturing.

About PyroGenesis Canada Inc.

PyroGenesis Canada Inc., a high-tech company, is a proud leader in the design, development, manufacture and commercialization of advanced plasma processes and sustainable solutions which reduce GHG and are economically attractive alternatives to conventional “dirty” processes. PyroGenesis has created proprietary, patented and advanced plasma technologies that are being vetted and adopted by multiple multibillion dollar industry leaders in four massive markets: iron ore pelletization, aluminum, waste management, and additive manufacturing. With a team of experienced engineers, scientists and technicians working out of its Montreal office, and its 3,800 m2 and 2,940 m2 manufacturing facilities, PyroGenesis maintains its competitive advantage by remaining at the forefront of technology development and commercialization. The operations are ISO 9001:2015 and AS9100D certified, having been ISO certified since 1997. For more information, please visit: www.pyrogenesis.com.
