A California-based cleantech pioneer – Blue Planet Ltd. – is learning from nature to make concrete more sustainable with biomimetic carbon capture. The company’s economically sustainable carbon capture process creates a limestone rock substitute that can replace aggregate for concrete, significantly reducing the material’s ultimate environmental impact.
Limestone Rock Substitute for Greener Concrete
As populations and economies grow worldwide, more buildings and infrastructure projects are being undertaken each year. This growth has serious consequences for the environment and, in the face of impending climate catastrophe, means to reduce this impact are a top priority.
Among the most harmful elements of this continual worldwide development is the widespread use of concrete as a building material. Concrete’s environmental consequences are well documented and come from a variety of factors. Among these is the need for large amounts of rock material for aggregate – which is environmentally costly to mine, transport, and implement.
