Græni steinninn is a thougt to be a leading civil engineering company dealing with environmental issues in the building industry. There is a lot to gain in environmental work for the construction industry and not least because the construction industry e.g. in Europe uses about 40% -50% of the continent's energy and raw materials. In addition, construction waste is the largest category of waste and the use of hazardous substances is significant. Our goal is to decrease the carbon footprint in the building industry with natural raw materials such as timber, hemp, bioplastic, mycelium, algae and possibly other natural raw materials. We are going to do life cycle assessments , LCA for our future clients so we can measure the carbon footprint on the natural houses to compare it with the most common one on the market today which are mostly made with concrete and steel with high carbon emission.

We have made contract with farmers in the south region of Iceland to grow hemp for fibers that is used in hempcrete which is made with limestone, hemp fibers and water and is spreading fast around the world. One benefit of using hempcrete and other natural raw materials is that when
at the end of its life cycle it can be torn down, crushed and applied to the fields as a lime additive for the soil. 100% natural cycle. We are in collaboration with the University of Reykjavík and Efla verkfræðistofa in our researches and development on those natural solutions. Greener and cleaner future is our main goal.
