Low global environmental impact
Products from STENI have a low carbon footprint. STENI’s products produce 14 to 17 kg CO2/m2. A life-cycle analysis has been conducted for STENI façade panels and all our panels have an Environmental Product Declaration (EPD) in accordance with ISO 14025/ISO 21930/EN15804/. The calculation has been performed and verified by a third party, SINTEF. EPD documents have been approved by EPD Norway and Institut Bauen und Umwelt e.V. (IBU).

No environmentally harmful substances
EU: None of STENI AS’s products contain substances on the REACH list.

Nordics: None of STENI ’s products contain substances on the REACH list, on the Norwegian priority list, the Sunda Hus priority list or the Nordic Ecolabel Appendix 6.

Long lifetime
With a long lifetime and low resource consumption for maintenance, STENI panels are an environmentally sound choice. The Life Cost Calculation (LCC) (NS 3454:2013) of a product is a good indication of the product’s resource consumption over time. Products from STENI have a low LCC.

Waste management
STENI sorts all waste internally in accordance with the Grønt Ansvar (Green Responsibility) scheme we have joined with Veolia Miljø. Grønt Ansvar is a comprehensive programme for documented and systematic waste management.

STENI façade panels are packaged using wood, paper and recyclable plastic. The packaging is adapted so that it can be easily sorted at the construction site. Offcuts / left-over panels can be delivered as general waste for standard waste collection.
