Decarbonization: Getting from Policy to Projects

How does one get from policy to project in the world of decarbonization?  First, we must understand decarbonization. The term “decarbonization” literally means the reduction of carbon.  In today’s world, it refers to the conversion to an economic system that sustainably reduces and compensates the emissions of carbon dioxide (CO₂) – the long-term goal being to…

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…

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,…
