Researchers from the University of Michigan have pioneered a groundbreaking technology: biodegradable wooden formwork made from sawdust, created using 3D printing.
This innovative method enables resource-efficient concrete construction and reduces waste in the construction industry by creating reusable formwork that can be recycled after concrete pouring.
The novel solution contributes to more sustainable construction, lowers environmental impact, and holds promise for future eco-friendly construction practices.
Biodegradable Wooden Formwork Revolutionizes Concrete Construction: Where Sustainability Meets Recycling.

In a game-changing development, a research team from the University of Michigan has introduced an environmentally friendly alternative for concrete formwork, using sawdust as its foundation. This innovation, fabricated through 3D printing, promises a more sustainable construction industry and a significant reduction in waste.
Traditionally, concrete formwork accounts for around 40% of concrete construction costs. Often discarded after concrete pouring, these formworks contribute to substantial resource wastage. However, led by Mania Aghaei Meibodi, the research team has devised a solution based on sawdust recycling. By employing biopolymers that are biodegradable, a material has been created that is easily recyclable and reusable.
The technology combines robot-controlled 3D printing with an innovative concrete casting process. The printed wooden formwork shapes the concrete, while the concrete stabilizes the wood and prevents deformities.
Once the concrete has cured, the formwork can be removed and entirely recycled. This approach not only reduces waste and resource consumption in the construction industry but also lessens the environmental impact associated with traditional disposal methods.
Muhammad Dayyem Khan, one of the researchers behind this technology, emphasized sustainability's significance: "Instead of [disposing of sawdust] by burning it and generating even more CO2 emissions, it's much better if we turn it into a material that can be used over and over again."
The development of these biodegradable and recyclable concrete formworks signifies a significant stride toward more sustainable construction practices. It showcases the potential to decrease waste and environmental burdens in the construction industry while promoting efficient construction procedures.
