Under a new purchase agreement, Lafarge Canada Inc. will assume the entire run of PozGlass 100G ground glass pozzolan—upward of 3,500 metric tons—from a pilot Progressive Planet facility in British Columbia, scheduled for 2024 start up. PozGlass 100G technology centers on a reactor equipped to transform the sodium in finely ground, post-consumer glass to sodium carbonate, formed with the introduction of carbon dioxide. In addition to a sequestered CO₂value proposition, the material can further lower the embodied carbon in concrete by offsetting the amount of portland cement in mix designs. PozGlass 100G presents as an alternative to fly ash, consistent supplies of which have been disrupted by early closure or planned retirement of coal-fired generating stations, or their conversion to natural gas fuel.

Lafarge Canada will provide Progressive Planet technical guidance and support as pilot PozGlass 100G plant design, construction, and operation proceed. The purchase agreement, notes Progressive Planet Vice President of Strategy and Investor Relations Ian Grant, “Is an enormous accomplishment [and] positions us for global licensing and royalties. Glass has virtually the same chemical composition worldwide, which lends itself to rapid scalability.”
