Holcim North America powers inaugural ash harvesting project

Initial ECOAsh deliveries from the Alberta processing plant are scheduled for this spring and will help stabilize fly ash supplies disrupted by the retirement of western Canada coal-fired power plants.

Holcim North America and sister business Geocycle North America are overseeing a premier of beneficiation technology transforming landfilled coal combustion products to Class F fly ash. ECOAsh, the branded material from an Alberta site strategic to Lafarge Canada Inc. operations, marks the first ash harvesting for concrete end uses under the global Holcim Group banner. Holcim NA and Geocycle NA are processing ECOAsh with the Ponded Ash Beneficiation System from Florida-based Ash-TEK.

“The transformation of landfill materials into high-value fly ash for sustainable building presents an exciting opportunity to build more with less and work towards a net-zero future,” says Lafarge, Western Canada CEO Brad Kohl. “At Holcim, we are fully dedicated to meeting future market demands by harnessing and enhancing extensive fly ash reserves secured through well-established, long-term sourcing agreements with electric utilities.”

“As we continue to build to support growing population demands, the integration of circular building materials such as ECOAsh plays a crucial role in driving our portfolio towards a more sustainable future,” adds Holcim Region Head, North America Toufic Tabbara. “By embracing these strategies, we not only provide essential building materials but also establish the foundation for building greener and smarter cities while shaping the trajectory of our industry for generations to come.”

ASTM International Committee C09 on Concrete and Concrete Aggregates will present Workshop on Next Generation Cements and SCMs: Towards Specification on June 9 in conjunction with standards development meetings in Philadelphia. Workshop organizers cite the rise of new concrete binding agents, often from start-up operators, that do not fall under existing specifications. The event will assemble producers, customers, agencies, and researchers with an eye to action moving new cements and supplementary cementitious materials toward specifications. Target topics include reactivity, standards, testing, data, product scaling, performance and durability. Additional information is available from workshop technical co-chairs Prannoy Suraneni, [email protected], and Anita Vuchkovska, [email protected].
