Biochar for Wastewater Treatment

Biochar for wastewater treatment, both municipal and industrial, is a good alternative as such multistage process accommodates a constantly changing influent. One of the most critical steps in the process is the aeration basin in which microbes work in conjunction with an adsorptive media such as biochar.  Biochar’s porosity makes it ideally suited to this…

Technical Readiness Assessment

As part of a technical due diligence effort, the team is often requested to perform a Technical Readiness Assessment.  This will assign a score to the technology, known as the Technical Readiness Level (TRL).  Originally developed by NASA in the 1970’s, it was adopted by the US DOD in the early 2000’s, followed by the…

Industrial Fermentation: Selecting the Host Strain

When developing an industrial fermentation process, the choice of the production organism dictates much of the large-scale fermentation characteristics in addition to the nature of research and development and process development.  Well characterized strains with a large genetic manipulation tool set, such as Escherichia coli, can rapidly deliver R&D goals, yet E. coli tends 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,…

Cannabis Certification Troubleshooting

Cannabis Certification Troubleshooting? Independent cannabis/hemp testing laboratories certify the potency and safety of products aimed at consumers. There is a notable lack of laboratory test standardization among state requirements due to the absence of Federal oversight, making product certification difficult to navigate for producers. Contamination from bacteria, fungi, pesticides, heavy metals, and solvents cause certification…

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…
