Hemp could hold the key to the future of carbon-neutral construction, according to researchers at the University of Bath.
Hemp is a fast-growing, non-intoxicating member of the cannabis family.
Working with a consortium led by the university’s BRE Centre for Innovative Construction Materials, the researchers have embarked on a project to develop the use of hemp-lime construction materials in the UK.
Hemp-lime is a lightweight composite material made of plant fibres bound together with a lime-based adhesive. The material offers a trio of benefits: lime has a low-carbon footprint, hemp-lime is an efficient insulator and hemp stores atmospheric carbon as it grows. The result, researchers say, is a construction material with a “better than zero” carbon footprint. …
