Hemp, the world’s most sustainable raw material, can be integrated into car bodies and used as a biofuel. Henry Ford was the first engineer to include hemp fibres in car parts. Meanwhile, premium manufacturers are discovering the advantages of hemp in car construction. Including hemp makes cars lighter and safer.
The largest building in the world is currently being built in the Nevada desert. Construction is not over yet, but Tesla’s Gigafactory already occupies a space measuring more than 1.9 million square metres (two million square feet ). It was commissioned by Elon Musk, one of the richest men in the world. Musk is hailed by many as the saviour of the ailing automotive industry. Since he declared war on the oil industry, he has rapidly moved from success to success with his car company Tesla.
However, climate experts agree that electric cars are not the panacea that some believe them to be. The production and disposal of lithium batteries are not only expensive, but also bad for the environment. There is a green alternative to steel and batteries that is little discussed but offers extremely good prospects: products based on hemp.
Hemp, the world’s most sustainable raw material
Hemp has been used for thousands of years for products such as ropes and clothing. After World War II growing hemp became illegal. This was partly due to the lobbying of DuPont, the American manufacturer of synthetic materials. Only in 2018 was the cultivation of hemp re-legalised in the USA.
“Fortunately!” says the CEO of HempFlax, Mark Reinders, when asked. “Hemp is the most sustainable raw material in the world. You don’t need pesticides for its cultivation because it grows faster than weeds. Yield per hectare is also amazing. From each hectare of hemp, we harvest 2000 kg of fibre, compared to about 400 kg of cotton.” HempFlax is the world leader in hemp production. The company, which was founded in 1993, cultivates hemp in the Netherlands, Germany and Romania.
The possibilities of hemp are endless. HempFlax hemp is used, for example, indoor panels for Mercedes, Bentley, Bugatti and BMW. Reinders says, “Door panels usually consist of plastic and fibre. Hemp is thirty times lighter than glass fibre, which reduces the fuel costs of cars. In addition, only one tenth of the energy is needed to produce hemp.”
So, is hemp cheaper than other fibres? Reinders hesitates, “Only if the oil price stays above 100 dollars per barrel, then we can keep up. Still, we are not too expensive. Indeed, glass fibre is far too cheap because manufacturers don’t pay for the environmental damage and CO2 emissions they cause.”
