GreenSand has 18 years of expertise in utilizing olivine gravel and sand for both construction and ecological purposes. In the Netherlands, it has established significant benchmarks through its certified olivine building materials. These materials have the unique ability to release a net clearance capacity of 1000kg CO2 per 1000kg used in a project. Such remarkable CO2 removal capabilities have led the Dutch National Environment Database to recognize GreenSand products as the first and only construction materials with a negative Environment-Cost indication score. The team consists on eight dedicated employees and collaborators who stand prepared to provide their services.
