  • U.S. Patent and Trademark Office has issued two unrelated US Patents to the Company, U.S. Patent. No. 9,447,705 and U.S. Patent No. 9,752,206;
  • The first targeting the Environmental Industry,
  • TThe second targeting the Mining and Metallurgy Industry, which brings the total number of issued and pending patents held by the Company to fifty-four

MONTREAL, Oct. 26, 2017 – PyroGenesis Canada Inc. ( (TSX-V:PYR) (OTCQB:PYRNF), a high-tech company (the “Company” or “PyroGenesis”) that designs, develops, manufactures and commercializes plasma waste-to-energy systems and plasma torch products, announces today that the U.S. Patent and Trademark Office has issued two unrelated US Patents to the Company, U.S. Patent. No. 9,447,705 and U.S. Patent No. 9,752,206; the first targeting the Environmental Industry, and the second targeting the Mining and Metallurgy Industry, which brings the total number of issued and pending patents held by the Company to fifty-four (54).

“We are happy to add these 2 new patents to our solid and substantial global intellectual property portfolio, which now consists of over 17 issued patents worldwide, and an additional 37 patent applications in progress”, said Pierre Carabin, Chief Technology Officer of PyroGenesis. “When combined with our know-how and significant trade secrets, we have over time created a formidable barrier to entry in the markets where we are active.”

U.S Patent. No. 9,447,705 – Maximizing Energy Recovery in Waste to Energy Processes

U.S Patent. No. 9,447,705 specifically relates to improving the recovery of energy in plasma gasification processes as well as conventional fossil fuel incinerators.  As applied to PyroGenesis’ waste-to-energy technologies, this patent provides an innovative way to capture waste heat from various components within the process (i.e. plasma torches, reaction vessels, cooling jackets amongst other high-temperature components requiring cooling), in addition to recovering energy from the hot process gas exhausts.

Building upon its proven track record and its proprietary technology, currently being used by the US Navy, PyroGenesis will now be able to offer systems with even higher efficiency to recover energy from waste for small and medium size applications. “Essentially, we are taking our existing cutting-edge technology and making it so much better”, said Mr. Carabin, “which underscores our philosophy at PyroGenesis to strive for innovation with the goal of making our own technologies obsolete.”

Of note, the waste-to-energy market is expected to grow at a compounded annual rate in excess of 5.5%, to exceed $35 billion by 20191.

U.S Patent. No. 9,752,206 – Plasma Torches Replace Fossil Fuel Burners

U.S Patent. No. 9,752,206 relates to using plasma torches instead of diesel burners in blast furnaces during iron ore pellet induration. Induration of iron ore pellets is an essential step in blast furnaces. The purpose of a blast furnace is to reduce and convert iron oxides into liquid iron called “hot metal”.  This process is traditionally heated by fuel burners.

The use of diesel burners is extremely pollutive as the process burns natural gas, heavy oil or pulverized coal. By using electric powered plasma torches, the generation of CO2 created by diesel burners is effectively eliminated.

The amount of pollution produced by these diesel burners is significant.  For example, a typical pellet plant producing 10 million metric tonnes of pellets annually emits approximately one million metric tonnes of CO2. The total world pellet production of 400 million metric tonnes of pellets therefore corresponds to the production of 40 million metric tonnes of CO2.  This is equivalent to 8.5 million cars on the road, year after year2.

“This new patent is a proprietary process whereby the generation of CO2 by the conventional iron ore pelletizing processes is reduced by using plasma torches powered by renewable electricity instead of burning a fossil fuel, resulting in a near zero emission process”, said Mr. Carabin. “Moreover, and most importantly, depending on the price of oil, electricity and carbon credits, replacing diesel burners with plasma troches can result in very significant and quick paybacks.”

The total world production of such iron pellets is approximately 400 million metric tonnes per year, which corresponds to about 20% of the total iron ore production.  Pellet production thermal energy consumption ranges between 600 and 1000 MJ/t3.  Assuming all this energy was replaced by 1 MW PyroGenesis’ plasma torches, the total number of torches required worldwide would be in the order of 10,000 units.  At current torch prices, this represents a market in excess of $7.5 billion.

“We have patent applications with similarly broad claims which are currently pending in Europe, Japan, China and other industrialized nations,” said Mr. Pierre Carabin. “We are extremely selective in terms of what intellectual property we patent, as funds for such expenditures are limited. This in part explains the high level of success in awards we receive as we only pursue those that have a high probability of success.”
