On the other side, the plant’s fiber is very fit to create an high quality of paper, while preserving world’s forests at the same time.
According to many scientists, hemp can also be used as an alternative to plastic, which is sometimes made with toxic chemical substances. Latest studies have also demonstrated the potential use of hemp to replace gasoline; this starts from the fact that for a lot of centuries oil made from the plant had been used as lamp oil. So, it could be interesting to try to focus on the potential use as renewable biofuel, with less carbon dioxide emissions, which can be useful to create a green friendly business.

To be more exact the product is known as ‘Hemcrete’ and it is a mix of industrial hemp, lime and water. It’s an ecofriendly way to build thanks to which it’s possible to create ecological buildings which can better fit the environmental needs in today’s world.
