Bushfires caused devastation across the south of Western Australia, but proved the fire resistant properties of hempcrete. The hemp-based building material, in the form of hempcrete blocks, survived the blaze.
What actually determines the effects of Cannabis sativa is the entourage effect of the cannabinoids, terpenes (hydrocarbons), terpenoids (oxygen-containing terpenes) and flavonoids along with their quantities, not a name.
Over the last several decades, diverse lignocellulosic biomass has been studied for the production of biofuels and biochemicals. Industrial hemp has great potential, with the increase of hemp-related markets including hemp seed, hemp oil and fibre.
Hemp has received a lot of attention because of its multipurpose usability, short production cycle, low capital demand in cultivation, possibility of carbon-negative transformation and easy carbon sequestering.
In Australia, industrial hemp is a plant or any part of a plant (including seed), from the genus Cannabis, that has been specifically bred to have tetrahydrocannabinol (THC) levels in the leaves and flowering heads of not more than 1%.
Some historians maintain Australia was established as a hemp colony to supply fibre to an increasingly fibre-hungry world. Sir Joseph Banks supplied hemp seed for the First Fleet. Free seed was given to settlers by early governors to encourage cultivation.
Cannabis today is the same plant that has been cultivated and used for thousands of years. However, due to the large number of varieties, the level of THC (the main neuroactive ingredient) differs widely.
