This report on decarbonisation options for the Dutch stone wool industry is part of the MIDDEN project (Manufacturing Industry Decarbonisation Data Exchange Network) initiated by PBL and ECN part of TNO. The project aims to support industry, policymakers, analysts and the energy sector in their common efforts to achieve deep decarbonisation.
Stone wool production in the Netherlands
Stone wool production in the Netherlands takes place at Rockwool NL B.V. in Roermond. The company produces 300 kilotonnes (kt) of stone wool products annually, from various minerals and recycling flows. The related CO2 emissions mainly come from the melting process and amount to 142 kilotonnes per year in 2017.
Decarbonisation options for stone wool production
On-site decarbonisation options consist of various energy efficiency measures and alternative fuels like biomass, biogas and hydrogen. Examples of energy efficiency measures are waste minimisation, insulation of the furnaces, regular machinery maintenance and waste recycling. Another important option is the electrification of the melting furnaces.
