Finnish firm unveils carbon-negative building material from forestry waste
MO6 tiles store twice as much CO₂ as wood and last for millennia
1Breakthrough in sustainable materials
Finnish company Elementic has developed MO6, a revolutionary building material composed of 90% carbon derived from forestry industry byproducts. Launched at Helsinki's Habitare fair in September 2024, this innovative product transforms typically discarded lignin into durable, fire-resistant tiles. The material represents a significant advancement in construction sustainability, offering both functional and environmental benefits while addressing waste reduction in the timber industry.
2The science behind MO6
Through a proprietary bioreactor process, Elementic removes oxygen and impurities from lignin to create a lightweight yet durable material. The patented technology converts this challenging byproduct into a versatile construction material with a unique aesthetic. MO6's general manager Johanna Normiala compares the process to baking, where lignin dough transforms into a hard, resistant final product. This innovation effectively repurposes a material that would otherwise be burned for energy.
3Unprecedented carbon storage
MO6 claims to be the world's most carbon-negative building material, storing approximately 2.4kg of atmospheric CO₂ per kilogram of product—double wood's capacity. Unlike organic materials that decay, MO6 maintains its carbon storage for potentially thousands of years while being fully recyclable. This breakthrough comes as architects increasingly prioritize carbon sequestration in building materials to combat construction-related emissions.
4Current applications and future potential
Currently marketed for premium interior spaces like hotels and spas, including a Parisian project, MO6 tiles are available in various finishes. While initially focused on dry indoor applications, Elementic is developing structural bricks for broader construction use. The company envisions large-scale building applications that could significantly impact the carbon footprint of future construction projects worldwide.
5Industry context and competition
MO6 enters a growing market of carbon-storing materials, joining innovations like Tarkett's carbon-negative linoleum. The construction sector's renewed interest in timber as a carbon sink has created demand for alternative solutions. Other lignin-based developments include German designer Basse Stittgen's bioplastic and Danish Natural Material Studio's structural panels, though none match MO6's claimed carbon storage capacity.
6Technical specifications
The MO6 Eternal collection features thick, lightweight tiles with a distinctive off-black color and rough texture. The material offers thermal and acoustic properties comparable to wood, with potential for further enhancement through manufacturing refinements. Elementic maintains secrecy around its exact production methods while emphasizing the material's premium design qualities for high-end commercial spaces.
7Environmental impact assessment
By utilizing forestry waste and creating long-term carbon storage, MO6 addresses two critical environmental challenges simultaneously. The product lifecycle—from renewable raw material sourcing to recyclability—represents a circular economy model. Experts suggest such innovations could help the construction industry meet ambitious carbon reduction targets set by governments and environmental organizations.
8The future of carbon-negative construction
Elementic's breakthrough signals a paradigm shift in sustainable building materials, offering architects new tools to combat climate change. As regulations tighten and carbon pricing evolves, materials like MO6 could become standard in green construction. The company's expansion plans into structural applications suggest this technology may soon reshape how buildings are designed and constructed globally.
