CO2 capture is increasingly viewed as an important technology towards meeting climate goals. Electrocatalytic systems excel at converting CO2 into C1 and C2 compounds, but are challenged in forming additional carbon bonds. Biological systems can build complex carbon compounds from simple carbon compounds, but are less efficient at upcycling CO2 due to gas diffusion limitations […]
Researchers have targeted the use of catalytic methods to reduce CO2 to single carbon intermediates, then to follow with biological up-conversion to multi-carbon compounds. In this project, Montana State researchers developed electrochemical reactor components with laterally graded pore structure to aid in reaction distribution when the reactor is scaled-up. Project partners integrated these components into […]
CO2 Electrolysis + Gas Fermentation: a CO2 to Chemicals Platform, that’s the goal of this Argonne National Lab, LanzaTech and Dioxide Materials, project. It aims for room Temperature CO2 electrolysis (Anion Exchange Membrane based technology), and gas fermentation yield improvement through process development, metabolic engineering and arginine supplementation. Researchers have found that gas fermentation can […]
Isobutanol (IBA), feedstock for an ASTM approved pathway for SAF production, can only be produced at low levels in fermentation (<2%) due to toxicity. Plus, there’s energy intensive recovery to consider – high heat input or high vacuum required to separate from aqueous broth. The goal of this project is to decrease energy use (by […]
Developing Carbon Negative Biorefinery with Gas-fermenting Bacteria is the focus of this project, focusing on Acetogens as model gas-fermenting anaerobes, with high energy efficiency and fast electron/carbon consumption making them potentially a new chassis for the production of biofuels and value-added chemicals. Wei Xiong of NREL led the team that created this presentation for DOE […]
The most recent ReEnergize episode webinar looked into liquid-liquid extraction strategies and technology for bioproducts and biofuels. As noted in the session, many biotech companies need help developing optimal separation processes for recovery and purification. Adequate experience and pilot testing is critical to optimize the design of the separation systems. Koch Modular Extraction Technology Manager, […]
The Bio-Optimized Technologies to keep Thermoplastics out of Landfills and the Environment (BOTTLE) consortium is developing new chemical upcycling strategies for today’s plastics and redesigning tomorrow’s plastics to be recyclable-by-design. BOTTLE conducts high-impact research and development to deliver scalable technologies that enable cost-effective recycling, upcycling, and increased energy efficiency for plastics. Under the BOTTLE research […]

Deconstruction is a major effort in the BOTTLE consortium; work spans exploratory catalysis (”fail fast”) to advancing promising approaches towards scale-up. In this BOTTLE project, the team looked at Chemical catalysis for C–C bond cleavage in mixed plastics waste for open-loop recycling and Chemical catalysis for PET and nylon deconstruction and closed loop recycling, while […]
