As a natural part of common efforts to achieve a greater degree of sustainability in the projects, we have an intention to build a broad and detailed knowledge of local materials. Consequently, the transport of materials can be significantly reduced, while at the same time the “from cradle to grave” principle can be easily realized. Currently, we have collected data and samples from Sealand’s largest gravel pits in order to gain more knowledge of local gravel, and stone materials and we have a vision of using more local materials in our projects.
