Exterra Carbon Solutions secures CAD $20 million funding to repurpose asbestos mine tailings into sustainable materials for a cleaner future.

Montreal Startup Exterra Carbon Solutions Launches Major Asbestos Mitigation Initiative

A fresh wave of excitement is sweeping through the environmental and mining sectors as Exterra Carbon Solutions, a Montreal-based startup, just bagged a whopping CAD $20 million (USD $14.5 million) in funding. This hefty investment aims to fuel the ambitious goal of repurposing toxic asbestos mine tailings into valuable, low-carbon energy transition materials, steering the province—and perhaps the world—toward a more sustainable future.

The Innovations Behind Exterra

Founded in 2021, Exterra has set its sights on an area often overlooked: asbestos mine tailings (AMT). These waste products, typically deemed environmental hazards, contain critical elements like nickel and magnesium that can be repurposed into essential minerals. The startup is currently on the brink of establishing what it claims will be the world’s largest asbestos mitigation facility, boasting an annual processing capacity of over 300,000 tons of AMT.

With Quebec sitting on a treasure trove of approximately 800 million tons of AMT, the province is poised to become a significant supplier of battery materials for the burgeoning electric vehicle (EV) market. This innovative approach not only helps reduce the need for new mining but also minimizes the associated environmental impacts.

A Sustainable Net-Zero Future

CEO Olivier Dufresne touts Exterra’s innovative strategies aimed at transforming mining waste into low-carbon products, thereby paving the way for a sustainable net-zero future. The startup has also developed two groundbreaking methods to repurpose mining waste: mineral extraction and carbon storage. The latter involves using a process to create magnesium carbonate from magnesium oxide—previously a process that contributed significantly to global carbon emissions. With Exterra’s method, carbon dioxide is sequestered, offering a dual benefit of producing cleaner goods.

Hub One: A Gamechanger in Asbestos Mitigation

An exciting development on the horizon is Exterra’s planned facility, dubbed Hub One, with a goal of processing an impressive 400,000 tons of asbestos mine tailings every year. Expected to be operational by 2027, potential sites include Thetford Mines or Val-des-Sources—historically known for asbestos production but now positioned for an environmentally friendly renaissance.

The Financial Backbone of Exterra’s Vision

The recent funding round was notably co-led by Clean Energy Ventures and BDC Capital, with backing from the Government of Quebec and private investors, underscoring the confidence placed in Exterra’s vision. As market collaboration partners, major companies such as BASF, Énergir, WSP, and Winsome Resources are stepping in to support the company’s growth trajectory, offering technical expertise to refine its technology and broaden its market presence.

Revenue Streams and Market Opportunities

As for revenue, Exterra is not solely relying on selling carbon credits, although it has already entered the voluntary market with sales to companies like Frontier Climate and MaRS. The startup plans to diversify its revenue model, including selling magnesium oxide, nickel products tailored for EV batteries, and continuing to generate environmental credits. Exterra’s business model aims to ensure sustainability and resilience amid the evolving environmental landscape.

Charting New Territory

The initiative by Exterra aligns with a broader shift in global mining practices and environmental responsibility. Notably, other Canadian companies like BAIE Minerals and Deep Sky are also experimenting with mining waste but differ in methods and approaches. This trend indicates a growing recognition of mining waste not as a liability, but as a valuable resource ripe for innovation.

As Exterra Carbon Solutions gear up for greater advancements in the asbestos mitigation space, it sparks hope that the fight against not only environmental degradation but also the grave health risks posed by asbestos can be met with formidable ingenuity and commitment to sustainable practices. Keep an eye on this dynamic startup as it transforms challenges into opportunities, forging a path toward a cleaner, greener tomorrow.
