CarbonQuest manufactures a modular Distributed Carbon Capture System (DCCS™) that uses solid sorbents and vacuum pressure swing adsorption (VPSA) technology to capture carbon dioxide from industrial emissions. The company serves biogas and RNG facilities, food and beverage manufacturers, and onsite low-carbon power generation operations. The captured CO₂ is converted into a monetizable resource through sales and offtake agreements.
