    Arca carbon tech funding: field‑scale mine waste mineralisation lens for engineers

    Arca carbon tech funding: field‑scale mine waste mineralisation lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Arca Technologies has secured up to C$2 million from NRC IRAP’s Clean Tech initiative towards a C$7.4 million project to move its mineral activation and engineered carbonation processes from lab to field scale, targeting alkaline wastes such as mine tailings and steel slag. The company will design containerised, field‑deployable mineralisation units and prepare a first‑of‑kind industrial pilot, billed as the first field‑scale system to accelerate carbon mineralisation in mine waste. Commercial traction includes a 10‑year offtake with Microsoft for nearly 300,000 tonnes of CO₂ removal and an early pre‑purchase from Frontier.

    Technical Brief

    • NRC IRAP Clean Tech support combines advisory services with up to C$2 million in non-dilutive funding.
    • Total project budget is C$7.4 million, structured as a research, development and demonstration (RD&D) programme.
    • Funding is explicitly targeted at moving Canada-developed “Industrial Mineralization” technology into operating industrial environments.
    • Arca’s process is framed around using alkaline wastes from mining, metals and steel manufacturing as feedstock.
    • Containerised units are intended to be engineered, manufactured and deployed domestically within Canada’s cleantech ecosystem.
    • Project scope includes field validation and partnership-building with industrial operators handling mine tailings and steel slag.
    • The initiative is positioned to create skilled engineering and manufacturing jobs tied to mineralisation plant deployment.
    • Canadian federal backing aims to reinforce mining and metals sectors by adding value pathways for by-products.

    Our Take

    With Uzbekistan’s gold exports valued at about US$1.5 billion through April and annual output around 130 tonnes, carbon-removal technologies like Arca’s could become a differentiator for gold producers seeking lower embedded emissions in a tightly scrutinised supply chain.

    Merdeka Gold Resources’ planned US$500 million Hong Kong float, noted in our database alongside this Environmental piece, signals that gold companies looking to tap public markets may face growing investor questions on decarbonisation tools such as Arca’s field-deployable carbon tech.

    WSP wins Environment Agency groundwater framework: modelling shifts for UK project teams

    WSP has been appointed to all three lots of the Environment Agency’s National Groundwater Modelling Framework, covering strategic modelling, regional and catchment-scale studies, and site-specific assessments. The framework will support regulation of abstraction, flood risk and drought management by standardising numerical groundwater models used to assess aquifer behaviour, contaminant migration and interactions with rivers and infrastructure. Consultants working on EA-regulated projects should expect closer alignment to EA-approved modelling tools, datasets and calibration approaches over the framework term.

    MKM EcoVadis Gold in the UK: sustainability and product shifts for specifiers

    EcoVadis has awarded MKM Building Supplies a Gold medal, placing the independent merchant in the top 5% of 150,000 companies assessed worldwide for environmental, ethical, labour and human rights, and sustainable procurement performance. Key measures include opening its first two BREEAM Excellent certified branches in Cheltenham and Wolverhampton, rolling out electric forklift trucks across the network, and tightening supplier requirements via a strengthened Code of Conduct. For specifiers and contractors, MKM is also widening access to renewable heating technologies, energy‑efficient products and lower‑carbon construction solutions aligned with evolving UK building regulations.

    NSW coal cuts emissions fastest: design and compliance signals for mine planners

    New South Wales coal mining has cut direct emissions by 30 per cent since 2005 and net emissions by 35 per cent once the federal Safeguard Mechanism is included, making it the fastest‑reducing sector in the state. The industry is now on track to meet legislated 2030 emissions targets, driven by mine‑site efficiency gains, progressive rehabilitation and changes in operational energy use. For mine planners and environmental engineers, the data signal mounting pressure on lagging sectors and a likely tightening of baseline and offset settings beyond 2030.
