Using Hemp in Building Insulation Could Make Structures Greener, Create Jobs, and Be a Profitable Industry

The team has published an analysis outlining a path toward a viable hemp-based building insulation market in the U.S. Hemp insulation can be used in place of traditional fiberglass batt insulation and reduce the carbon footprint of buildings, but hemp materials currently cost twice as much.

CEE researchers’ analysis outlines path to a U.S. construction market for hemp-based fibers, which are already used for clothing and biodegradable plastics.
It’s a fairly niche product now, but a new study from Georgia Tech engineers suggests insulation made from hemp fibers could be a viable industry in the U.S., creating jobs, a manufacturing base, and greener homes and buildings at the same time.
Making the switch could slash the impact of one of the biggest sources of greenhouse gas emissions: Buildings account for roughly 1/5 of emissions globally. By some estimates, using hemp-based products would reduce the environmental impact of insulation by 90% or more.
The Georgia Tech researchers’ work, reported this month in the Journal of Cleaner Production, is one of the first studies to evaluate the potential for scaling up U.S. production and availability of hemp-based insulation products.
