As a renewable raw material, wood stores CO₂ and can eventually be returned to the natural cycle. What’s more, when considered over its entire life cycle – from harvesting to processing to transport – the energy balance and sustainability of wood are unbeatable. That’s why building with wood also means taking responsibility – for current and future generations.

Wood as a material

Wood is a renewable resource. Sustainably managed forests continuously produce new building material. At the same time, the wood already used in buildings continues to absorb CO₂ over the long term. This is also building sustainably with wood: the short transport routes from the local forest to the sawmill and planing mill conserve resources and strengthen local value creation. Most of Blumer Lehmann’s round timber comes from the local area – and is processed in its entirety. A cycle that works.

Sustainability of wood in a closed cycle

From the tree to the building and back again: at Blumer Lehmann, wood passes through an entire value chain. In the sawmill, planing mill and finger-jointing mill, around 170,000 m³ of Swiss logs are turned into a comprehensive range of construction products every year. Whatever is not used as construction material is turned into carbon-neutral pellets, residual timber products and energy. At the end of the building’s useful life, the wood can be reused or thermally recycled – with no waste at all.

A variety of future-proof designs

Wood demonstrates its sustainability and the benefits associated with it in a variety of forms and constructions: modular construction, prefabricated construction, timber hybrid construction and Free Form. In addition to the natural advantages of wood as a construction material, prefabricated modules enable short construction times and high quality. Hybrid constructions combine wood with other materials where it makes sense to do so. Finally, Free Form timber constructions demonstrate the extraordinary architectural visions that can be achieved with wood. Building sustainably with wood is future-proof construction for the world of tomorrow.

More than just ecology

Fire protection, sound insulation, energy efficiency – timber constructions also meet the highest technical standards. Building sustainably with wood also means adopting a holistic approach to design and optimising material use. This enables the creation of buildings that are not only environmentally friendly, but also economically viable and functional. Timber’s valuable natural properties further enhance its sustainability. They promote a healthy indoor climate and create a sense of comfort that has a direct impact on well-being.

Measurable quality

Labels and standards such as Swiss wood, SNBS, Minergie and FSC make building sustainably with wood verifiable. They document that a building, a material or a construction method meets defined ecological, economic and social criteria. We see these standards as a guide to responsible construction. We ensure that our products and projects comply with them.

Sustainability at Blumer Lehmann: three dimensions, one goal

For us, sustainability means more than just ecology. In all our decisions, we consider business, social and environmental criteria in equal measure. Specifically: our biomass power plant makes the Gossau site self-sufficient in terms of energy. We continuously train apprentices and provide career prospects for more than 600 employees. We also strive for excellence that creates lasting value – for customers, employees and future generations.
