Sustainability and Resource Efficiency at FOS®

Our 10-point plan

At FOS®, sustainability means using resources consciously and making specific measures transparent. This includes materials with high recycled content, the recovery and recycling of transport packaging, photovoltaics, air-source heat pumps and waste heat recovery, as well as manufacturing at our sites in Germany.

Resource efficiency at FOS® in figures

  • average recycled content of around 80% in material input
  • up to 90% recycled content in stainless steels and wires
  • 30–70% recycled content in aluminium, depending on the alloy
  • cardboard packaging made from 100% recycled cardboard material
  • 52 kWp photovoltaic system at the Hemer site
  • around 44,000 kWh annual yield and around 75% self-consumption
  • Interzero certificate 2025: calculated savings of 494 tonnes of primary resources and 43,421 kilograms of greenhouse gases

Our 10-point plan for resource efficiency and climate action

  1. Products made from steel and aluminium: single-grade, fully recyclable and with an average recycled content of around 80% in material input.
  2. Cardboard packaging made from 100% recycled cardboard material.
  3. Recovery and recycling of registered transport packaging through Interzero.
  4. Products designed for a long service life and the use of corrosion-resistant materials.
  5. Preference for regional suppliers with short transport distances of up to 100 km.
  6. Manufacturing exclusively at our sites in Germany.
  7. Fair working conditions and local engagement.
  8. Heat generation using air-source heat pumps and waste heat recovery.
  9. Renewable electricity generation from photovoltaic systems.
  10. EcoVadis Sustainability Rating as an external assessment of our sustainability management.

Materials and recycled content

FOS® clips are manufactured from materials including stainless steel, wire and aluminium. According to the available material data, stainless steels and wires contain up to 90% recycled content. For aluminium, recycled content ranges from 30 to 70%, depending on the alloy. Across material input, the average recycled content is around 80%.

Technical suitability remains the priority: material quality, corrosion resistance, fit and the product properties required for the specific application determine the choice of material.

Packaging recovery through Interzero

Our cardboard packaging is made from 100% recycled cardboard material. In Germany and Austria FOS® works with Interzero for registered transport and commercial sales packaging. The packaging is collected and, where technically possible and economically reasonable, recycled as material.

For 2025, the Interzero certificate for FOS® reports calculated savings of 494 tonnes of primary resources and 43,421 kilograms of greenhouse gases. The figures are based on the calculation methodology stated in the certificate.

Energy at the Hemer site

At its Hemer site, FOS® operates a photovoltaic system with a capacity of 52 kWp. According to the available system data, annual yield is around 44,000 kWh, with approximately 75% of the generated solar electricity used directly on site. FOS® also uses air-source heat pumps and waste heat recovery for heat generation.

Manufacturing in Germany

FOS® manufactures at its sites in Hemer, North Rhine-Westphalia, and Treuen, Saxony. This keeps manufacturing, technical expertise and quality testing closely connected within the company.

EcoVadis assesses our sustainability management

FOS® is externally assessed through the EcoVadis Sustainability Rating. EcoVadis is not a product or company certification. Where a current medal or badge is used publicly, the assessment year and the relevant EcoVadis Recognition Page should be included.
