Sublime Systems produces low-carbon cement aimed at reducing the environmental impact of traditional cement manufacturing. Their unique process eliminates the need for a kiln, which is typically the most energy-intensive part of cement production. The low-carbon cement they offer performs similarly to conventional cement but with significantly lower CO2 emissions, making it appealing to construction professionals looking to minimize their environmental footprint. Unlike competitors, Sublime Systems focuses on a sustainable approach without sacrificing performance, and they sell their product by the metric ton for large-scale projects. Their goal is to commercialize this low-carbon cement and work towards achieving zero emissions in the future.
