Most wood waste in Norway is in the current practice treated with energy recovery, which implies both direct and indirect emissions, but also has benefits for providing electricity and district heating that substitutes other energy production. The future end-of-life of wood products would probably be quite different than the average practice today. Increased focus on material recycling will probably influence wood waste in Norway, but also carbon capture and storage combined with energy recovery are planned for.
In recent years, the request for EPDs on building products according to the EN 15804 standard has increased and many wood product manufacturers have developed EPDs. The modelling of end-of-life requires to interpret the technical specifications in standards and gather data from statistics. However, where to find the data and finding the right way to model can be challenging, so the practice has changed in several steps over the years. This article describes experiences from developing and implementing end-of-life modelling in 50 wood product EPDs that were verified by EPD Norway related to requirements in standards and usability in a building context.
