Progressive Planet Solutions Inc (TSX-V:PLAN) said it has filed a patent application for the PozGlass 100G product it is developing.
PozGlass 100G is made from finely ground post-consumer glass, which is diverted from landfill. Ground glass pozzolan has historically been used to replace up to 30% of cement in concrete to improve performance and reduce its carbon footprint but it contains sodium. When sodium is reduced, it is stronger and better able to reduce alkali-silica reactivity (ASR).
The company said its patent application covers a process where PozGlass100G permanently sequesters CO2 while reducing sodium.
"Having moved production in-house with the commissioning of the PozGlass 100G Demonstration Plant in June, results came down to the wire with our best results to date coming just 4 days prior to our application deadline of July 16," said Ian Grant, chief operating officer (COO) of PLAN.

"Being able to include these results in the patent was significant and couldn't have happened without the sacrifices and extra efforts of our team. We are excited about the future of PozGlass 100G and proud of our in-house team of engineers, scientists, technicians, millwrights, and management which worked tirelessly to meet this patent deadline at the same time that we scaled up from lab scale to our bench scale system at our head office in Kamloops, BC," he added.
The next phase towards commercialization will increase the production rate of PozGlass 100G from bench to pilot scale during which PLAN said it will measure parameters such as:
- How fast can the post-consumer glass be processed
- Total energy consumed in production
- Total CO2 sequestered by the process and,
- Concrete performance
The pilot scale project is projected to take nine months, the company added.
Progressive Planet makes agricultural, household, and industrial products with two new cement products under development including PozGlass 100G and Poz DE.
PozGlass 100G is made from post-consumer glass diverted from landfills and Poz DE is made from waste rock powder generated during the production of the company's core products.
