PUREVAP™ TECHNOLOGY
ONE-STEP LOW-EMISSION TRANSFORMATION OF QUARTZ TO HIGH-PURITY SILICON
The PUREVAP™ is a one-step proprietary process that uses a plasma arc within a vacuum furnace to produce high-purity silicon from quartz. It is expected that the silicon grades produced by PUREVAP™ could be used for diverse manufacturing applications.
PUREVAP™ works by reducing quartz with carbon using a plasma submerged arc. Under vacuum, and at very low operating pressure, the silicon is refined in a one-step process removing all impurities and transforming it to its purest form, resulting in a high purity silicon.
Having patented proprietary scalable and low emissions silicon material-producing technology such as the PUREVAP sets the stage for HPQ to scale as needed, to fulfil growing demand quickly. The company’s strategic location of Montreal in North America adds another advantage in that it is close to the end-user, decreasing transportation costs and eliminating international supply chain disruptions that often plague the logistics sector.

PRIORITISING ESG
For our investors, our portfolio firms, and the communities we serve, we are certain that the more we integrate ESG elements into our corporate mission and performance, the more value we will be able to create.
OUR APPROACH
HPQ produces high-purity silicon in a far more efficient manner relative to standard methods, reducing overall costs, greenhouse gas emissions, and necessary feedstock materials. This gives HPQ a decisive cost advantage which can be passed along its value chain.
THE PUREVAP™
ADVANTAGE
Our PUREVAP™ projects are designed with superior operational efficiency relative to conventional silicon manufacturing techniques.
The PUREVAP™ Quartz Reduction Reactor uses 25% less material feedstock to produce 1MT of high-purity (>99.5%) silicon metal for a 20% cost advantage.
