Carbon Dioxide Remediation or Removal in Biogas

What is the difference between carbon dioxide remediation and removal in biogas? Both are processes that change the raw biogas to another useful form, but there is a distinction.  Carbon dioxide removal is a form of remediation, but it is a more sophisticated and costly step in the “cleanup” of biogas.  Normally, the reason to…

Biogas

Biogas is a gas mixture developed from naturally occurring processes in nature.  Basically, bacteria that exist in our world digest organic material, and the by-product of their digestion is biogas.  Biogas is a mixture mainly of methane and carbon dioxide, but invariably contains many other compounds.  Some of the more significant compounds are considered contaminates,…

Biogas Conversion to RNG

Given the ideal circumstances, landfills offer good biogas conversion to RNG possibilities. Landfills produce a very large volume of biogas that can be converted to Renewable Natural Gas.  Landfills are typically very large, and when they have been designed to efficiently retrieve the generated biogas from the landfill, it is usually a very large volume,…

Ethanol Proteins – Advanced Process Monitoring

Ethanol plants achieve the best quality ethanol proteins through advanced process monitoring and control.   That means starting with consistent control of corn grinding, cook and liquefaction and fermentation so that each fermentation batch is very consistent in terms of starch converted to ethanol.  Most ethanol plants were designed with simple DCS process control and simple…

Ethanol Protein – Importance of Co-Product Quality

Why is the importance of ethanol protein co-product quality? At least eight ethanol plants have recently installed new process technology that separates higher value corn fermentation protein from whole stillage. This ethanol protein is a combination of corn protein and yeast protein from the ethanol fermentation process. This protein product is destined for growing animal…

Site Planning to Mitigate Environmental Risks

In well-developed bioeconomy projects, initial site planning, placement of facilities, and mitigation of potential environmental risks, are the factors that help improves a project’s chance of overall economic success.  It is critical for project developers and land managers to work together in developing optimization models that guide systematic, multi-objective planning efforts, collectively including biodiversity and…

Biomass Wildlife Impact

It is well known that sustainable feedstock development is the cornerstone of the bioeconomy, but does sustainable biomass production  encompasses things like wildlife impact, and more than just reliable annual yields of high-quality feedstock?  Biomass provides habitat for our nation’s wildlife resources, a source for capturing carbon in our soils, material that can intercept and…

Biofuels Market Studies

Biofuels market studies are useful in many ways.  Let’s start at the beginning. Biofuels are fuels produced from renewable organic material, commonly referred to as biomass which includes plant materials, crops and animal waste. Secondary biofuels include transportation biofuels such as ethanol and biodiesel. Biofuels are substitutes for conventional fossil fuels, such as petroleum, propane,…
