Hemp Plastics; Hemp is a high-yielding crop, making it an excellent source of these environmentally friendly plastics known as ‘bioplastics.’ They are light, biodegradable, and can be used to substitute a variety of petrochemical plastics (oil-based plastics). Cost; Hemp plastic is currently selling for $2.35 per pound, according to Mark Linday of Green Springs Technologies. Since it does not rely on petroleum as a source, hemp based plastic is also less costly to manufacture and biodegradable. A Canadian research team recently produced hemp-based graphene that is 300 times stronger than steel and costs less. Decomposition; There is no comparison between the decomposition of hemp plastics and conventional plastics. A typical plastic bottle takes 450 years to decompose, while hemp plastic can biodegrade in as little as six months in the right conditions….
