But there are so many uses and benefits with industrial hemp and “you’re looking at anything from cosmetics, medicinal, biomass, textiles, fibre, plastics and biofuels. “And, literally when you’re harvesting it, the foliage and leaves that fall off, naturally as it dries out in the field, re-nitrates the soil. So, you don’t have to put nitrates back into the soil, it already does that … You don’t need fertilisers and pesticides and all that stuff to grow it.

“Hemp is a descriptive term that refers to the non-psychoactive uses and varieties of the cannabis plant,” said Hemporium director and co-founderOn the environmental benefits of industrial hemp, Budden noted that “one plant has a multitude of uses, it does not require pesticides or herbicides, conditions the soil, absorbs carbon, uses less water than cotton and is zero-waste.

There will always be some carbon produced on the harvesting or processing side “but most of that is offset with the amount of carbon hemp absorbs while it is growing – it’s a better than zero carbon crop”, Budden added. This is particularly true in the construction sector. , which is hemp mixed with lime,” he said, explaining that this goes through a process of calcification where the lime and the hemp bond and form calcium carbonate.

Industrial hemp can take up metals and store them in different parts of the plant, with no detriment to the plant itself. Hemp grown for phytoremediation of contaminated soils also produces marketable products used for bioenergy production, timber fibre, pulp, and fodder.“In comparison, forests capture two to six tonnes, depending on the type of trees, region, etc.

For Cramer, the sky’s the limit. “Eighty percent of the plastics that go to BMW are hemp-based plastics so it lowers their carbon tax. We are aiming to tap into those markets,” he said.
