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 115% of
the water demand of the control mix.
The water demand for PozPyro was between 99% and
109% for all test batches and as such PozPyro demonstrated
excellent workability.
STRENGTH ACTIVITY INDEX
(SAI)
The SAI is an industry standard for measuring
the compressive strength of cement mortar cubes. As announced in a
press release on April 11, 2024, the results of the 7-day testing
that showed an approximate average +45% SAI gain across four tests
against the minimum target value.
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.
TESTING AGAINST MINIMUM COMPLIANCE (75%
PORTLAND CEMENT MPA)
For SAI tests, a cement additive product test is
acceptable at a minimum strength of 75% of the control product
strength.i For one Series B test, the Portland Cement control
achieved a compressive strength value of 36.18 MPa at 28 days. An
additive product would therefore be acceptable based on achieving
27.14 MPa (equating to 75% of the Portland Cement control
strength).
The results for the individual Series B test
showed a blend of Portland Cement containing 20% PozPyro far
surpassed this target, achieving a peak result of 54.15 MPa – a
result 99.56% higher than the minimum acceptable value.
The overall average gain for all tests in both
series A and B was +67.43% against the minimum compliant for an
acceptable cement additive product.
TESTING AGAINST MAXIMUM COMPLIANCE (100%
PORTLAND CEMENT MPA)
When compared to a 100% value of Portland Cement
alone, this same Series B PozPyro/Portland Cement blend test
surpassed even the full-strength value of the Portland Cement
control product by up to 49.67%.
The overall average gain for all tests in both
series A and B was +25% against the maximum product compliance for
an acceptable cement additive product. This result means
that the PozPyro material, when added to Portland Cement at a
20%/80% blend, outperformed a cement-only Portland Cement control
in strength tests by 25%.
“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
75% of the control, but when compared to a full value of the
control the PozPyro green cement additive showed a 49.67% gain. In
other words, these tests suggest that not only can PozPyro
potentially outperform other traditional cement additive products
in strength, it has the potential to directly outperform pure
cement alone. As I’ve stated before, the cement industry is a key
target for us, and we have high expectations for the PozPyro green
cement additive material.”

Series A and Series B strength tests, measured at 7- and 28-days in
megapascals (MPa) of a 20% PozPyro/80% Portland Cement blend
against a 100% pure Portland Cement control, a 20% fly ash blend, a
20% ground granulated blast-furnace slag (GGBFS) blend, and a 20%
silica fume blend produced using traditional methods.
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.”

Portland Cement control, 20% fly ash blend, 20% ground granulated
blast-furnace slag (GGBFS) blend, and 20% silica fume blend.
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 4% between 2024 and 2032. Assuming that pozzolanic cements could
be a substitute for 20% of Portland Cement, the total addressable
North American market is projected to reach over 55 million tons by
2032. At a projected price of US$200 per ton by 2032, the potential
market is over $11 billion USD per annum by that time.
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.
