U of Göttingen researchers use popcorn to create eco-friendly insulation material

Researchers at the University of Göttingen are using popcorn to create a less expensive, more environmentally friendly insulation material.

The researchers wanted to address the fact that roughly 90% of insulation is made from petroleum-based plastic or mineral fiber, which generate carbon during manufacturing and are rarely recycled when a building is torn down.

The research team has developed insulation boards made of granulated popcorn that trap warmth in while also offering protection against fire and water damage.

“This new process, based on that of the plastics industry, enables the cost-effective production of insulation boards at an industrial scale,” says lead researcher Alireza Kharazipour. “Especially in the field of insulation in construction, this ensures that natural insulation materials are no longer just niche products.”

According to Kharazipour, the novel material feels like polystyrene and is just as lightweight, yet it poses no threat to the environment or to human health.

The University of Göttingen has licensed the technology to Bachl Group, a German building material company.

“We are delighted to be launching such an innovative insulation product using popcorn onto the market together with the University of Göttingen,” says Michael Küblbeck, managing director of Bachl Group. “Popcorn insulation complements our quality range perfectly and means we can respond even more precisely to the different requirements of the market and our customers.”
