South Australia’s Hemp Houses Seem Like Next Sustainable Option

It has massive potential and there’s lots of interest in being able to build houses now from hemp,” said the University of Adelaide’s Professor Rachel Burton, Researcher in the School of Agriculture, Food and Wine.

Hemp is emerging as a greener alternative to more traditional materials, such as bricks and concrete, for building more energy efficient buildings

This is one of the topics in the University’s latest podcast series, The Discovery Pod. The series covers diverse subjects from hemp homes to using dogs to sniff out diseases and how computers may be used to help treat mental illness.

“Hemp is an extremely good insulator. It has been recognised that it controls humidity and it provides a lovely living environment for humans,” said Professor Burton.

“It’s fire retardant, so ideal for Australian conditions and maybe California and other places that are hot and dry.”

Industrial hemp is a type of cannabis that doesn’t have high levels of THC – the chemical that triggers the “high” associated with marijuana.

It is a good crop alternative for farmers and well-suited to South Australia’s climate.

Fibres from inside the plant’s stem can be mixed with water and lime to produce a concrete-like mixture, known as hempcrete, which can be used to create bricks or the fibres can be used in pre-cast panels for sound-proofing or insulation.

“There are still many barriers to producing hempcrete but hemp houses and other plant-based products have huge potential to change how we build. People are looking for more environmentally friendly ways to reduce reliance on scarce resources.”
