The manufacturer’s Blue Planet investment builds on a 2021 technical collaboration netting an efficient carbon capture assembly. It has been demonstrated to permanently sequester up to 440 kg of CO 2 per metric ton of aggregate.Ī Sulzer Chemtech carbon dioxide absorber column serves the pilot San Francisco Bay Aggregates mineralizing operation. The Blue Planet process forms carbonate minerals and synthetic limestone by combining CO 2 and metal ions-each captured or sourced from heavy industry emissions or waste streams.

The Swiss fluid engineering specialist joins prior round investors, including North American cement, aggregate and concrete producers Holcim Group and Knife River Corp., plus Chevron and Mitsubishi Corp. Sulzer Chemtech is among participants in the latest funding round for California-based Blue Planet Systems Corp., whose carbon dioxide capture technology yields mineralized, concrete-grade aggregate.
