Prodexim International Inc.

Published purpose

This collaborative Project aims to develop an innovative and cost-effective beneficiation process for transforming high-carbon fly ash and legacy coal ash from landfills and ponds into high-quality cementitious materials that meet construction standards. A key focus will be the development of new second-generation passivating agents, which are essential for neutralizing residual carbon effects and will be pivotal to the Project's success. Additionally, the initiative will prioritize the creation of second-generation milling aids designed for ultra-fine milling to achieve particle sizes under 20 microns, enhancing the quality of the resulting cementitious materials. A collaboration between Prodexim, two industrial partners, the Université de Sherbrooke and the NRC, the Project seeks to establish a non-proprietary process that recycles fly ash and lowers CO2 emissions from cement production. Anticipated outcomes include a replicable process that fosters a sustainable Canadian supply of construction materials from waste, creates new job opportunities, and utilizes Canadian expertise and resources.
