RE:RE:RE:The Globe & Mail Article: PYR/HPQ Fumed Silica covered!PYR really has close ties with McGill University.
Jean-Rene Gagnon has been with PYR since 2005 and has graduated from McGill.
It's also very interesting to read that PYR has McGill emeritus Prof. Munz as a consultant as he's the one behind using plasma to produce fumed silica with less GHG.
PyroGenesis announced Wednesday it had secured an additional $630,000 from Technoclimat, a Quebec government green energy fund, to develop low-cost, environmentally friendly fumed silica processes. This follows a grant of $700,000 from Sustainable Development Technology Canada, an armslength federal foundation, announced in May. The project is currently in its trial period, and is expected to produce 50 tonnes of fumed silica in its first year, staring in July, 2022. HPQ Silicon holds intellectual property rights for the reactor process through its subsidiary, HPQ Polvere, and the process is patent protected.
“Scaling up these types of processes is our specialty at PyroGenesis, but we know there’s going to be a lot of fine tuning ... before we’re making kilos and kilos of this stuff that is of the right quality for our suppliers’ needs,” said Jean-Ren Gagnon, lead process engineer at PyroGenesis Canada.
The company’s new technique builds on the work of McGill University emeritus professor Richard Munz, now a consultant on the project.
“The current method used by companies in China and Europe uses a lot of chlorine, so it’s expensive, and it’s not very environmentally friendly,” said Dr. Munz, who started studying the process in the 1990s. “Our idea was to make the same material, using only electricity and plasma technology to ideally make it more cheaply at the same or better quality.”
Plasma is the fourth state of matter, after solid, liquid and gas. In the same way a solid turns to a liquid when energy is applied – such as ice melting into water – a shift to plasma occurs when a gas is given more energy through the transmission of electricity.
Plasma is used in the automobile, medical device and transport industries. PyroGenesis specializes in using plasma technology to create products for the defence, mining, metallurgy and waste-management sectors.
PyroGenesis’s new plasma method proposes to expose quartz to an electric arc in a manner similar to lightning, Mr. Gagnon said.
“We put the quartz in the reactor and subject it to high temperature, and it vaporizes into very small particles. Then we’re able to resolidify it as this very, very fine powder,” he said.
The two companies hope it will bring fumed silica production to Canada. Current big players in the market include Boston-based Cabot Corp., Germany’s Evonik Industries AG and China’s Henan Xunyu Chemical Co., Ltd., all large-scale chemical companies.
“It’s not a huge market in the way that other natural resources are, like wood or electricity. But at a market value of US$1.5-billion, it’s certainly worth it commercially for us to enter. Even if we get 5-10% of that business in the first few years, it’s still an immense amount of money,” Mr. Gagnon said.
The new production method wouldn’t replace current ones – at least, not any time soon – given the size of investments in existing infrastructure. But Dr. Munz said the initiative could be an opportunity to invest in a Canadian exportable good.
Mr. Gagnon said the project also makes particular sense in Quebec, where renewable energy from hydro plants is cheap and quartz is abundant. Most of Canada’s quartz reserves are in the province, as well as in Ontario and Alberta.
If successful, the companies plan to scale up production to thousands of tonnes a year.
“It would put Quebec on the map for an environmentally friendly way of producing a very important industrial material,” Dr. Munz said. “There’s a long way to go, but we’ve been successful and we’re going to keep going.”
We’re moving into an environment where ESG principles are there for everybody, so the buyers of a material now have to be conscious of its carbon footprint.
