Of all the uses for hemp, a real Mind-Opener is all the different sorts of building materials it provides:
Hemp based materials can replace wood and other materials used to build homes and other structures including foundations, walls, shingles, paneling, pipes, and paint. You can make it into insulation as companies in the Netherlands and Ireland are already doing. Hemp can even be used to make ‘hempcrete’, a stronger, lighter, and more environmentally friendly version of concrete, which is lightweight, waterproof, fireproof, self-insulating and resistant to pests..
Houses built from hemp have been found to use less energy, create less waste and take less fuel to heat than conventionally constructed homes.
