Sustainability at MAG45

Which suppliers we approve. Which materials pass. How many times a tool is used before it is replaced. How much stock is written off because nobody had visibility on it. Those decisions are made every day in the tail of the supply chain, and together they add up to a real environmental footprint.

That is exactly where we operate. Tail supply is the long list of non-strategic items that represents a small share of spend and a very large share of transactions, suppliers, and paperwork. It is also the part of the supply chain that is hardest to see into. Bringing it under one integrated management structure is what makes it measurable, and measurable is where improvement starts.

Why sustainability is a core principle, not an add-on

In tail supply, the sustainable choice and the cost-effective choice are usually the same choice.

Reconditioning a tool instead of buying a new one. Returning a component to stock instead of scrapping it. Consolidating forty small shipments into one. Each of these lowers Total Cost of Ownership (TCO) and reduces material, energy, and transport at the same time.

That is why we do not treat sustainability as a trade-off against efficiency. Running integrated tail supply for manufacturers of complex machines means every sourcing and logistics decision ripples across the chain. For our clients that shows up as a lower TCO, and for their ESG reporting it shows up as fewer new parts purchased, less waste, and better documented supply chains. One set of decisions, two sets of results.

Sustainable sourcing, reuse, and reconditioning

Two places where a decision in the tail supply chain shows up in both the cost base and the environmental footprint.

That is exactly where we operate. Tail supply is the long list of non-strategic items that represents a small share of spend and a very large share of transactions, suppliers, and paperwork. It is also the part of the supply chain that is hardest to see into. Bringing it under one integrated management structure is what makes it measurable, and measurable is where improvement starts.

1. Sustainable sourcing: knowing what is actually in your parts

Every component in the tail carries a compliance and material profile, and in most organizations nobody owns it. Sourcing is not a procurement problem, a quality problem, or an engineering problem. It is all three, which is why it often ends up being nobody’s.

We have been doing the essential work of managing certificates, validating materials, and keeping clients audit-ready for over 75 years. We manage supplier selection, collect and maintain material documentation, and look for alternatives when a material becomes a risk.

Example: For one high-tech machinery manufacturer we are working through thousands of tail supply components to answer three questions per part: does it contain PFAS, can the supplier certify that, and is there a PFAS-free alternative that meets the same performance specification? The goal is a PFAS-free supply chain by 2030, ahead of the EU restriction that ECHA is due to advise on.

2. Reuse and reconditioning: keeping components in circulation

Two routes keep a component out of the scrap stream. Reuse puts an unchanged part back into service. Working with our clients, we set up reuse loops for items that are commonly treated as consumables. They are collected, cleaned in a cleanroom process, checked against the original specification, and returned to stock. One of our clients reuses over 100,000 items a year this way, and that number is expected to grow to 200,000. The quality bar does not move: tools such as drills can be used three to four times after cleanroom cleaning without dropping below the original specification, which is what makes them acceptable in regulated production environments.

Reconditioning goes a step further and restores a worn tool, and it works best when it is designed in, not retrofitted later. For a fast-growing manufacturer we built reconditioning into the supply strategy from the launch of their new production facility in 2023, starting with a single CNC machine and scaling as the site grew to dozens of machines. High-value tools make up around 10 percent of the tool range but nearly 30 percent of total tool costs, so that is where the effort pays off. Some of those tools cost more than 1,000 euro each.

Every cycle a tool does not have to be manufactured is raw material, energy, and transport that is never used. That is why reuse and reconditioning show up in the cost base and in the emissions figure at the same time.

Independently assessed

We would rather point to what has been verified by someone else than describe our own ambitions.

EcoVadis Silver, top 15 percent worldwide

MAG45 earned the EcoVadis Silver medal in April 2026, placing us in the top 15 percent of companies assessed worldwide. EcoVadis is an independent platform that evaluates the quality of a company’s sustainability management system across environment, labor and human rights, ethics, and sustainable procurement. The Silver medal reflects how we operate across the board, not just one corner of the business.

ISO 9001:2015  ·  Quality management

Specifies the requirements for our quality management system, ensuring a structured approach to consistently meeting client and regulatory requirements.

United Nations Global Compact

MAG45 is part of Solar Group, a signatory to the UN Global Compact and its Ten Principles on human rights, labor, environment, and anti-corruption. Solar Group sets the ESG framework we operate within.

Both ISO certifications are issued and audited by an accredited independent body. Our EcoVadis Silver medal is not the finish line. As part of Solar Group, which holds the EcoVadis Gold medal, we operate within a group assessed at the highest EcoVadis level, and we are already working on what is next for MAG45: sharper emissions reporting and deeper circularity with our suppliers and clients.

Beyond doing less harm

Reducing damage is the minimum, not the destination. The more interesting question for manufacturers is which parts of the supply chain can actively give something back: materials that stay in circulation, packaging that leaves a smaller footprint than what it replaces, suppliers that get better because we ask them to.

Grass-based cartons are one example. They carry a carbon footprint 50 percent lower than traditional cardboard, because grass is sourced faster than wood. Small, consistent choices across a large supply chain.

That is a longer conversation than a certificate, and it is one our CEO Bauke Zeinstra keeps having with clients and suppliers.

Community involvement

Beyond our operations, MAG45 employees support local initiatives. Recent activities include collecting books for the Books4Life charity, collecting stamps for charity, and facilitating activities for people with disabilities in the local area.
