The Moelven Group is one of Scandinavia's leading timber companies. Their Glulam competence and technology are world-leading, as demonstrated by the construction of the world's tallest timber building, the Mjøsa Tower in Norway, and the Stavanger Financial Centre, one of Europe's largest commercial buildings to be built in wood. Moelven's relentless focus on quality results in buildings that are "Built to last". Their Glulam joist and beams for commercial buildings sequester CO2 in a 100-year perspective.
Moelven Limtre AS and Moelven Töreboda AB have production facilities in Norway and Sweden, where they produce glulam elements for the construction industry. Timber is sourced from local spruce and pine forests that are sustainably managed and certified with the PEFC chain-of-custody.
As trees grow, they capture CO2. One ton of wood absorbs 1,8 tons of CO2 during the growth period, but the CO2 will be released back into the atmosphere if the tree decomposes or is used for paper or energy. However, in the case of wooden building elements, carbon is stored in the building for the long-term, disrupting the normal carbon cycle and creating a net-negative process because sustainable forestry ensures that trees are re-planted. In the case of Scandinavia, overall forest coverage has increased over the last 40 years.
In Europe, buildings are regulated to have a minimum lifetime of 50 years, but in reality, the CO2 storage is likely to be much longer in real life. By storing CO2 for a minimum of 50 years, wooden building elements present an opportunity for companies to invest in carbon capture and storage and take proactive steps towards carbon net-zero.
Moelven's ISO-certified, modern, and highly efficient production technology reduces waste to an absolute minimum. Waste byproducts are upcycled or re-used. Moelven's glulam products are cut-to-order and delivered to the customers. The potential for waste at the construction site is almost non-existent, nonetheless, a 1% additional safety margin is included to be certain of the carbon storage calculation, in addition to the 10% safety margin required by the Puro.Earth methodology for wooden building elements.
Cut-to-order beams and joists for houses, schools, and commercial properties.
Each cubic meter of glulam beam stores 541 kg of the CO2 that the timber absorbed from the atmosphere during its growth period. Using the LCA methodology, Moelven can accurately measure the net carbon content of each timber building element that is produced. All emissions from the harvesting of the timber, transport to the production facility, through to the production and packaging of the products are accounted for in the Environmental Product Declaration (EPD) made by NORSUS and audited by Asplan Viak, following the methodology described in ISO 14044 and ISO 14064 standards. DNV GL audited the facility and documentation for the issuance of Puro CORCs in December 2020.
Moelven Glulam is in tough competition for projects with traditional steel and concrete suppliers in the commercial property sector. Revenue from CORCs will allow investment in electrification and general process efficiencies that enable them to be more competitive and win project tenders, compounding the climate effect and accelerating the carbon net-negative economy.
