Industrial hemp has been grown in over 30 industrialized nations for the past several decades. Hemp is primarily produced and processed for food and fiber, and is a component in thousands of products. In the U.S., the industrial hemp industry is re-emerging after an 80-year hiatus. This sustainable agricultural crop can be grown without pesticides or chemicals, and needs one-third to one-quarter the water required for corn, soy, wheat or cotton. Traditional and new farmers are increasingly planting hemp as a profitable crop that is good for the environment and rebuilds the soil.
One of the most interesting areas that hemp is being used is in the building materials sector. A growing number of people are becoming aware of “hempcrete” a mixture of hemp hurd, lime and water that is packed between wooden studs as an alternative form of eco-friendly insulation. Another even more promising product are hemp blocks made from the same three ingredients but formed into large “lego-like” blocks and used as the wall of the building.
In addition to the health care sector where CBD products are gaining momentum in foods, beverages, nutritional supplements, tinctures, topical balms, and beauty products, the construction industry offers a prime arena for industrial hemp. The crop is currently being used at a small scale for textiles and as a resilient green building product and has enormous opportunity for increased growth in the U.S.
Hemp is excellent as a non-woven insulation for walls and blown-in insulation for floors, walls, and attics meeting consumer demand for a healthy and sustainable building material.The fibers provide a non-toxic anti-viral solution that is a highly durable and long-lasting ingredient in composite building products such as OSB, fiberboard, and particleboard.
