Building Better: Bio-based Materials in Construction 🏗️
Is the building industry experiencing a green renaissance?
Currently responsible for nearly 40% of global carbon emissions and 40-50% of extracted raw materials, it's clear the construction sector urgently needs sustainable solutions. Architects, scientists, and businesses are racing toward innovations that reduce environmental footprints while delivering practical performance.
In this edition, we explore groundbreaking developments—from mycelium homes to seaweed panels and 15-story high wood buildings—that prove nature might just be our best construction partner yet!
📈 Business Developments
🍄 Mycelium Magic: Czechia’s Fungus-Based Home
Czech Technical University researchers and the national startup Mykilio have constructed Samorot, one of the world’s first houses made from reishi mushroom mycelium combined with renewable materials such as wood and cellulose. Using a whopping 1,800 kg of mycelium composite, this innovative project highlights the potential of fungi as a robust, biodegradable alternative to fossil-based materials like polystyrene.
The first-ever functional mycelium home?
🌶️ Turning Plant Waste into Building Blocks
Family-run business Dijkshoorn Bleiswijk in the Netherlands has creatively repurposed plant-based waste like pepper chips into fiber-rich, bio-based building materials. Their sustainable approach separates sap from fiber, supported financially through a national tax benefit scheme, setting a pioneering example in agricultural waste valorization.
🌳 High-Rise Wood Wonders: The Urban Woods Project
The Urban Woods, based in the Netherlands, is constructing large-scale buildings using a unique blend of wood structures and flax inner walls—no concrete shafts needed! Designed for adaptability, net-zero energy use, and 85% reusability, these buildings demonstrate that sustainable construction can indeed rise high—up to fifteen stories!
🚧 BioSpan Technologies Paves the Sustainable Way
US-based BioSpan Technologies has introduced a Partner Program to expand its eco-friendly pavement solutions like RePlay—a soybean-based asphalt preservative suitable for roads, driveways, and parking lots. This initiative invites businesses of all scales to participate, enhancing sustainability in construction and municipal infrastructure maintenance.
What else is rising behind the scaffolding?
- Cambium raises $18.5 million to transform waste wood into sustainable building material with AI
- Ekolution commissions an advanced bast fiber line for hemp fiber without impurities
🌱 Research & Innovation
🏖️ Concrete, but Better: Carbon-Negative Building Material
At Northwestern University, researcher Alessandro Rotta Loria and his team have developed a groundbreaking carbon-negative material from seawater, electricity, and CO₂. This innovative, sand-like substance directly replaces traditional sand in cement, paints, and plasters without the need to dig up the Earth.

🌊 Seaweed to the Rescue: Sustainable Construction Panels
Scientists at Mexico's UNAM, under Miriam Estévez González's leadership, have created Sargapanel—a sturdy, fire-retardant, and insulating construction panel made from invasive sargassum seaweed combined with gypsum. This recyclable innovation not only combats ecological threats posed by seaweed invasions but also offers potentially scalable, sustainable building solutions.
📚 Market Analysis
📈 Rapid Growth in Bio-Based Building Materials Market
