There are many other areas where hemp can be used. Hemp is a valuable source of biofuels. Hemp can also be used in biocomposite materials to replace plastics in applications as diverse as automotive panels and surfboards. There is also research underway to replace graphene in industrial batteries with hemp filaments.
Hemp absorbs more CO2 than any other, broadacre, crop and draws heavy metals from soils. It is therefore a great means of sequestering carbon and rehabilitating derelict land. This also means that crops for food and medicine need to be grown in soils that are not contaminated and in areas of low pollution. This is an advantage that Australia has over countries with less stringent environmental regulations. Due to hemp’s capacity to absorb CO2 hemp growers and manufacturers can be largely carbon neutral.
