Hemp seed is a great food source. Hemp is better to make paper out of than wood, although as we continue to transition to digital formats, that need is becoming less prevalent, but still prevalent enough to be relevant nonetheless. I read an article not too far back that showed hemp is likely to be used to make more efficient batteries in the future. It appears that hemp is a stellar building material too, creating a material that absorbs pollutants while also improving insulation compared to petroleum products. Per Green Optimistic : \n \n Just because a building has to be solid and tough, it does not mean that the materials used to construct it have to be hard-core polluting steel and concrete. Not long ago we drew your attention to eco-friendly cement , which can be used in the making of concrete, now it is time to move on to other eco-friendly materials. A team of scientists from University of Bath, UK, working under the HIVE project , has set their eyes on using hemp as a replacement to oil-based products in insulating materials. \nTo be more precise, the guys decided to focus on hemp-lime and hemp fiber. Building materials made of these were found to have perfect insulating properties, they absorb moisture from the air, and can control the internal temperature of the building. To make the material suitable for construction, all that is needed is to mix the hemp with lime-based binder and turn it into highly resistant to fire and decay building panels. \n \n Building with hemp materials is a win-win every way you look at it. It helps the environment, it’s cost effective, and it’s efficient. Petroleum based building materials are harmful to the environment, get more expensive all the time, and don’t work nearly as well as hemp based products. I can’t wait until someday when I can afford to build a house made out of hemp!
