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 […]
By Cynthia Thyfault, CEO, QuantaVision Special to The Digest The US Securities and Exchange Commission recently finalized a climate disclosure rule that has sparked intense debate across political, corporate, and environmental spheres. Initially expected to align with the stringent climate regulations of the European Union, the SEC’s rule emerged significantly watered down after two years […]
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 […]
LanzaTech is back in the news with a budding venture based in manufacturing single-cell protein — usually a side product — as the main product for a new set of biorefineries they have in the pipeline. Plus, an ultra-low carbon footprint compared to business as usual. It’s not strictly a protein shake, but protein is […]
By Sam Rushing, President, Advanced Cryogenics, Ltd. Special to The Digest When the average citizen thinks in terms of CO2, from a non- industrial gas perspective, often the thought surrounds concepts covering greenhouse gases, and global warming. On the other hand, in the gas field, thinking in terms of my past tenure with a former […]
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, […]
1. There used to be a lot of excitement around Planet X in days gone by, but it’s nothing like the excitement around Planet Twelve these days, or rather the company known as Twelve. They’ve done something rather unusual for the bioeconomy. 2. For many, the usual script calls for stalling on technology development or […]
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 […]
