What does a biochar expert do? First, let’s define biochar. Biochar is the carbonaceous material produced by the combustion of biomass. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years. It can be considered a method of sequestering carbon and has been shown to improve crop yields.…
“Good Manufacturing Practices” (GMPs) is a term describing a body of regulations promulgated by the Food and Drug Administration (FDA). These are listed in the Code of Federal Regulations under part 21; they are numerous, extensive, and complex. As a result, there exists a myriad of very similar definitions which attempt to describe the entirety…
Bio-processing may involve aerobic fermentation, whereas ethanol and chemicals from starches and lignocellulosic materials are generally anaerobic processes. Aerobic fermentation is a metabolic process by which cells metabolize sugars via fermentation in the presence of oxygen and occurs through the repression of normal respiratory metabolism. Aerobic fermentation occurs in the presence of oxygen. It usually…
Cellulosic Hydrolysis Reactors? Cellulosic materials, such as corn stover, cane, switchgrass, timber waste, municipal solid waste, etc., can be processed into fuels and renewable chemicals. Broadly speaking, there are two main methods: pyrolysis and hydrolysis. The former is relatively independent of feedstock but happens at high temperatures and may have yield losses due to breakdown…
Sometimes we think of fermentation in terms preserving foods or producing alcoholic beverages or acidic dairy products. But the term “fermentation” encompasses much. Fermentation waste treatment is the production of chemical changes in wastes via some enzymatic action. This is normally done to make the waste into a useable product like biofuels. Just as…
Pyrolysis Oil – Commercial Markets are a Reality. Did you know that new commercial-scale pyrolysis oil plants have recently come into play? Did you know that customers are buying pyrolysis oil in Sweden, Finland, Netherlands and the US? Did you know that for the first time pyrolysis oil is being shipped in volume by sea?…
CO2 Utilization? Carbon dioxide (C02), is a colorless and odorless gas that occurs in nature and serves as source of carbon for photosynthesis in all plants and crops. CO2 utilization’ refers to its use at concentrations above atmospheric levels, directly or as a feedstock in industrial or chemical processes, to produce valuable carbon-containing product. Energy…
Pyrolysis tire processing is a growing business worldwide thanks to advances in pyrolysis technology. It is a good thing, because tires are highly durable and non-biodegradable, and they took up lots of landfill space. In 1990, it was estimated that over 1 billion scrap tires were in stockpiles in the United States. Recycling these waste…
