    Circularity
    starts
    with a REAZN

    Sustainability
    is our foundation

    At REAZN, business and sustainability go hand in hand. Our goal is to build a long-term, sustainable supply of prime-grade zinc alloys, made primarily from secondary raw materials. Because zinc is infinitely recyclable, every tonne we recycle is a tonne of primary raw material the world doesn’t need to extract.

    That’s how we aim to reduce the footprint of our company, our products, and the zinc industry as a whole.

    Circular economy and urban mining

    An important part of our vision is to lead the transition to a closed-loop zinc alloy industry with the lowest possible environmental impact together with our customers, suppliers and partners.

    From by-products to prime-grade alloy

    REAZN turns industrial by-products into ready-to-use prime-grade alloys, cutting the industry’s dependence on primary zinc. Less primary zinc means fewer resources used and a lower carbon footprint, industry-wide. To make participation easy, we provide closing-the-loop boxes and a full logistics service to collect recyclable materials from our customers’ sites.

    Mining the city, not the earth

    We also recover zinc from post-consumer goods. Tapping the urban mine reduces virgin resource use and keeps valuable materials out of the demolition and household waste streams. We keep investing in recycling technology to push recovery rates higher and save more zinc from the waste stream every year.

    88% recycled content, sometimes 100%

    Our ZAMAK products made in Belgium contain on average 88% recycled material and some even on 100%. That makes them a natural fit for eco-design. In production, we achieve zero material loss, keeping not just zinc but also aluminium, copper and magnesium in the loop.

    Upcycling & recycling

    REAZN upcycles zinc-containing industrial by-products and post-consumer scrap into high-quality zinc alloys, reducing the environmental impact. Ultimately, this results in fewer mining and transportation activities, saving resources and reducing the industry’s carbon footprint.

    End of use

    Zinc die-casting parts are renowned for their durability. These robust components are commonly found in various everyday items. Thanks to their exceptional longevity, they often remain functional for many years. However, what occurs when they have served their intended purpose

    Zinc Scrap

    REAZN offers closed-loop solutions for transforming industrial by-products into ready-to-use alloys and provides the necessary logistical services for material collection. Additionally, REAZN aims to recover zinc from post-consumer goods, which helps to reduce resource inputs and prevent waste disposal.

    Corporate carbon footprint diagram showing Scope 1, 2, and 3 emissions breakdown at REAZN, with Scope 1 at 2%, Scope 2 near zero, and Scope 3 at 98%

    Our corporate
    carbon footprint

    We calculate our Scope 1, 2 and 3 emissions in line with the Greenhouse Gas Protocol. Since 2023, our Belgian plant has reduced its combined Scope 1 and Scope 2 emissions intensity by 29%, measured as kgCO2e per tonne of product produced.

    Since 2023, we’ve calculated the REAZN Group’s Corporate Carbon Footprint annually, covering Scope 1, 2 and 3 in line with the Greenhouse Gas Protocol.

    The breakdown tells a clear story:

    Scope 1: 3% of total emissions
    Scope 2: near zero, thanks to green electricity
    Scope 3: 97%, where the real challenge lies

    That’s why our in-depth Scope 3 calculation is central to our decarbonisation strategy leading us to setting long-term decarbonisation targets to keep us on track.

    Life cycle
    assessments

    We carry out full LCAs across our product portfolio, compliant with ISO 14040:2006 and ISO 14044:2006, assessing impact across 16 categories. As expected, “Resource use: minerals and metals” and “Climate change” dominate and that’s exactly where our circular model pays off.

    Compared to European primary zinc production, our alloys deliver:

    Up to 73% lower CO₂ footprint
    86% less natural resource use
    86% less water consumption

    LCA studies now cover 95% of our product categories. A summary report is available on request and under NDA.

    REAZN also contributed to the sector-wide LCA for recycled Zamak published by the International Zinc Association (IZA), helping set the industry benchmark. This benchmark number has been published in the EcoInvent database.

    Beyond carbon:
    water, air
    and energy

    Our environmental commitment goes further than emissions. At our Belgium site, we have:

    Solar: 1,664 panels · 975 MWh/year  · 173,500 kg CO₂ avoided
    E‑mobility: Full electric fleet · powered by own renewable energy · charging: 35 cars + 16 bikes
    Water: 2,100 m³ rainwater buffer · covers almost all of production process water use  
    Air: Our air filter can reduce the dust emissions 10 times lower than the legal limit

    Principles
    we stand by

    REAZN is a signatory of the United Nations Global Compact, aligning our strategy with its ten principles on human rights, labour, environment and anti-corruption.

    We’ve translated those principles into our own Code of Conduct, backed by team-wide training. We expect the same standards from our Business Partners, alongside compliance with national and international law and our Business Partner Code of Conduct.

    Our people

    We work to create a workplace where health and safety come first, where training and development open real paths to grow, and where diversity shapes how we operate every day. Beyond our own walls, we give back to the communities around our sites through local initiatives.

    Our supply chain

    Our global supplier network is built on long-term relationships and mutual trust. We work proactively to prevent risks from unsustainable practices, non-compliance or unethical conduct building a value chain that’s resilient as well as responsible. Our Sustainable Procurement Policy takes that commitment further, embedding environmental, social and ethical criteria into how we buy and how we sell. Responsible sourcing, responsible sales, the whole value chain.

    Compliance
    & certifications

    Responsibility is at the core of everything we do. REAZN complies with all applicable legal obligations and goes further by committing to recognised international standards.

    We are a member of the UN Global Compact, and in February 2026 we were awarded the EcoVadis Gold Medal, placing us among the top rated companies in the global benchmark for sustainability ratings. This reflects how we hold ourselves accountable to ethical, transparent and sustainable business conduct.
