CLT’s carbon stocks and carbon footprint
Wood absorbs carbon dioxide from the atmosphere during photosynthesis and converts it into carbon (C) and oxygen (O2). Carbon is retained in the wood, and the wood releases oxygen back into the atmosphere. There are about a billion solid cubic metres (1 solid cubic meter is about 1 m³) of wood ready for use in Finnish forests.
After the manufacturing process, one cubic meter of CLT slabs contains 676 kilogrammes of carbon dioxide. HOISKO’s CLT slabs have an annual production of 40,000 cubic metres, which means 27 tonnes of recovered carbon dioxide. A building’s carbon footprint consists of manufacturing, transportation, site handling, use and maintenance, and demolition and reuse operations. According to studies, the use of solid wood in construction produces less emissions than other materials. Solid wood serves as a long-term carbon store throughout its life. HOISKO CLT = an active carbon dioxide restorer.
The by-products generated in production are fully utilised in HOISKO for further processing and chipping. All surplus pieces from door and window openings are recycled. Any edge pieces of the elements and other extra pieces and sawdust are delivered to Vapo, which uses them to make pellets. Our business premises are also heated with pellets. In addition, the rest of the individual boards used in the production of CLT slabs are chopped and sold for firewood. We make full use of our raw materials, so there is no waste. For this reason, HOISKO CLT is an excellent choice for environmentally conscious builders.
