MONTREAL, May 02, 2024 (GLOBE NEWSWIRE) -- PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX: PYR) (OTCQX: PYRGF) (FRA: 8PY), a 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) and address environmental pollutants, is pleased to announce today that it has been advised by its client, Progressive Planet, that the latest series of compressive strength tests on its PozPyro green cement additive product reveal impressive results, posting strength comparisons significantly above the acceptable standard for similar material. PozPyro enhances the strength of concrete as a replacement for fly ash, which is in diminishing supply.
PozPyro, a cement alternative, is being developed in collaboration with Progressive Planet as a supplementary cementing material (SCM) designed to partially replace traditional Portland Cement. Of note, Portland Cement emits substantial amounts of CO2 during its production. PozPyro, on the other hand, is created by using a PyroGenesis plasma-based process that transforms quartz silica, a widely available material, into a SCM (PozPyro), without off-gassing CO2 during the production process. This innovation comes at a time when the cement industry seeks more sustainable practices without compromising quality or performance.
“Quartz silica is one of the most abundant materials in the earth’s crust,” said P. Peter Pascali, President and CEO of PyroGenesis. “The ability to economically convert it into PozPyro could offer a new supply of material to compensate for the diminishing supply of fly ash, a common SCM, which, by the way, is generated by the same coal fired power plants which are being targeted for shut down in Canada by 2030.”
According to Progressive Planet’s news release today, concrete producers are looking for SCMs that (i) increase the compressive strength of their mix while at the same time (ii) lowering their carbon footprint without sacrificing workability.
WORKABILITY
The workability of cement is measured by water demand and is a measure of its ease of use in various concrete applications. The smaller the water demand number, the better the reading. A passing water demand number must be less than
The water demand for PozPyro was between

In the 28-day tests announced today, Portland Cement was used as the control product, with varied compressive strengths between 35.26 and 39.62 megapascals (MPa) depending on the test.
These tests were conducted in two series, A and B, with two tests in each series, using different input variables to test for optimized results.

“These 28-day test results confirm the impressive results achieved by the previous 7-day tests, and underscore yet again the potential transformative nature of plasma in producing materials, in both an economically and environmentally beneficial manner, that are key to heavy industry,” said P. Peter Pascali, President and CEO of PyroGenesis. “Not only were we able to far surpass the minimum acceptable product standard compared to

Steve Harpur, CEO of Progressive Planet, commented on the results over the last month during which Progressive Planet prepared four separate batches of cement mortar cubes to test, under the American Society for Testing and Materials (“ASTM”) testing protocol, at both 7 and 28 days for compressive strength: “These results were exceptional and provide us the technical confidence to take the next steps to bring this product to market. In the Pacific Northwest alone, over one million tons of fly ash will cease to be generated by the summer of 2025 at which time two massive thermal coal to energy facilities will have finished converting from burning coal to natural gas.”

CO2 EMISSIONS / LACK THEREOF
While compressive strength is key to overall product viability, the reduction of CO2 emissions achieved by using PyroGenesis’ plasma technology, a low carbon emitting process, has the potential to offer further “green” benefits.
CO2 emissions within a product lifecycle are defined globally within 3 categories: Scope 1, Scope 2, and Scope.
Generally speaking:
- Scope 1 emissions are direct greenhouse gas emissions caused by the company’s production processes.
- Scope 2 emissions are indirect emissions, that factors in the use of energy purchased externally (and the CO2 created as a result of that energy being originally produced).
- Scope 3 emissions represent the CO2 emissions from operations upstream and downstream of the company’s operations, such as raw material production, transportation, waste, and end of life remediation.
When compared to other traditional cement additives, the production of PozPyro may result in dramatically lower CO2 emissions. For the purposes of the graph below, Scope 2 emissions regarding electricity usage have been factored into PozPyro’s emission level. Without these Scope 2 emissions, the greenhouse gas emissions released during the production of PozPyro may be virtually zero.
Image 3: A comparison of CO2 emitted during the production of 1 tonne of PozPyro vs. other cement additive products. CO2 emission assigned to PozPyro comes from production of electricity subsequently used by the process, not from the process itself.
“These are the best results we have ever seen in an alternative cementing material. The fact that silica-based cements do not off gas CO2 is an additional bonus to the exceptional compressive strength results,” added Steve Gurney, President of Progressive Planet.

POTENTIAL ADRESSABLE MARKET
According to Progressive Planet’s press release of today, it was noted that the North American cement market size reached 194.2 million US tons in 2023, and they expect that it will reach 279.8 million tons by 2032, reflecting an annual growth rate of
NEXT STEPS: PILOT PLANT
Now that the compressive strength of PozPyro has been validated, the next critical step is to progress towards the Pilot Plant stage. In preparation for this phase, an engineering feasibility study will be conducted over the next several months. This comprehensive study will focus on quantifying various critical elements to ensure the economic viability of the pilot plant operations. Key considerations will include maximizing heat recovery and other efficiency metrics, which are essential for sustainable and cost-effective production.
We are committed to rigorous evaluation and optimization processes, aiming to address all technical and economic aspects of the pilot plant. Updates on our progress and findings from the feasibility study will be provided in due course, as we move closer to achieving a fully operational pilot plant that meets our high standards for innovation and efficiency.
PyroGenesis’ involvement in developing PozPyro from quartz is part of PyroGenesis’ three-tiered solution ecosystem that aligns with economic drivers that are key to global heavy industry. PozPyro 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.
