Patent-Pending Technology Converts “Waste” Carbon Into Valuable Chemicals and Useful Elements

[ad_1] Waste carbon from farms, sewage and other sources can be processed into high-grade bio-based fuels more easily with a new PNNL-developed flow cell. In this animation, the flow cell receives biocrude and wastewater from a hydrothermal liquefaction process. It then removes carbon from wastewater, allowing the clean water to be reused. The system even […]
