Anaerobic Digesters: Methane Formation

Anaerobic Digesters: Methane Formation. The inter-microbial distances influence the biodegradation rates and specific growth in the formation of Methane. The microorganisms that form methane are physiological. They can grow only with a few specific substrates, such as H2 and CO2, formate, methanol, and acetate, and they, therefore, depend on others. Therefore, a syntrophic relationship is…

More Rubber Extraction Refineries Coming?

Are more rubber extraction refineries in our future?  In 2004, the History Channel broadcast a Modern Marvels Special on Natural Rubber. My favorite quote from that special is “Our four most important natural resources are air, water, petroleum, and rubber.” (I would have argued for soil to be part of the list.) Nonetheless, while most…

Organic Acids: Key Facilitators of the Bio-economy

Organic Acids: Key Facilitators of the Bio-economy? Recent declines in oil prices and the failure of start-up biofuel processes to meet production cost targets have increased the interest in producing value added chemicals from biomass as coproducts. The vision is that these products can leverage the production of fuel by providing revenue to supplement the…

Early-stage, Breakthrough Technologies: Biofuels, 10 of the Best

The concept of early stage, breakthrough biofuels technologies is a bit of an oxymoron.  At an early stage how does one determine if it something is a “breakthrough” biofuels technology? This article, first published in 2016, is still relevant today. The only way to determine if something is truly a “breakthrough” technology is for experts…
