Spain: Rockwool Peninsular plans to invest €60m to decarbonise production at its Caparroso stone wool insulation plant in Navarre by 2028. The upgrade centres on a €48.8m replacement of the plant's furnace with electric burners. It will receive €18m of Spanish government Strategic Project for Economic Recovery and Transformation funding. The project will reduce the plant's CO₂ emissions by 74%, to 13,300t CO₂-equivalent/yr. It also includes a hybrid wind and solar power plant expansion to generate 24GWh/yr for use at the plant. The Navarre government designated the project of ‘chartered region interest’ on 29 July 2026, approximately halving administrative procedural timeframes.
