Sustainability
Sustainability starts with the chemistry.
TripleHard® replaces carcinogenic hexavalent chromium with trivalent chromium in hard chrome plating, in manufacturers' own plants under a Savroc licence. This page sets out the REACH position and the environmental and occupational-safety case for the change.
The biggest environmental decision in conventional hard chrome plating is the chemistry itself. TripleHard® is made in a Cr(III) hard-chrome process, and the chemistry stays inside the continuous line. Below is what we do across Environment, Social and Governance, and how impact will be measured before any figure is published.
Principles
What ESG means at Savroc
Environment
- TripleHard® is a nickel and trivalent chromium coating that replaces Cr(VI) hard chrome. That is the product.
- Our technology helps customers move off the Cr(VI) chemistry that needs a REACH authorisation, and reduce emissions, chemical use and waste.
- We work continuously to lower energy and water use and material losses per part coated.
Social
- A safe and inclusive workplace, starting with a Cr(III) hard-chrome process in place of Cr(VI) chemistry.
- Competence built through training and open feedback.
- Transparent dealings with customers and partners, and respect for human rights across the value chain.
Governance
- Good governance, ethical principles and legal obligations, followed as a matter of course.
- The management team and the board oversee the impact methodology and report on progress.
- Information security, data protection and risk management are part of the management system.
By design
Built into the process, not bolted on
-
Cr(III) in place of Cr(VI).
Cr(VI) is a carcinogenic substance of very high concern under REACH. TripleHard® is a nickel and trivalent chromium (Cr(III)) coating made in a Cr(III) hard-chrome process: no chromic acid in the bath.
-
A fully enclosed line.
Chemicals stay inside the line, and splash, mist and emissions are contained. A trivalent bath holds many times less chromium, so the ventilation and wastewater treatment it needs are much smaller.
-
Less chemistry, less waste.
The enclosed line uses less chemistry and produces less waste than open-tank Cr(VI) plating.
REACH status, November 2026: ECHA has proposed an EU-wide restriction of hexavalent chromium substances under REACH. The Committee for Risk Assessment (RAC) adopted its opinion in June 2026; the Committee for Socio-Economic Analysis (SEAC) is finalising its opinion after the public consultation that closed on 19 August 2026. The final decision rests with the European Commission and the Member States.
Impact methodology
How we will measure impact.
Impact figures are published only after they have been measured against a 2027 production baseline on the continuous line. Until then this page states the method, not the numbers: a published figure without a measurement behind it is worth nothing to the people who have to defend it in a supplier assessment. This principle applies to impact figures for the continuous TripleHard® reference line in Kuopio; the case studies may cite third-party estimates for individual field cases, with their sources.
| Element | Approach |
|---|---|
| Functional unit | Per m² coated |
| Comparison baseline | A hexavalent (Cr(VI)) hard-chrome line coating comparable parts |
| Metrics | Energy, water, chemical consumption, worker exposure, waste |
| Method | Life-cycle assessment following ISO 14040/14044 |
| Baseline period | 2027 production on the continuous line |
| Review | Third-party review |
Planned No impact figures are published until they have been measured against the 2027 baseline.
ESG documentation for your supplier assessment
If your procurement process needs documentation on TripleHard®, the line or Savroc as a supplier, ask. We answer with the documents and the method, not a brochure.
