Coal Gasification

Coal has historically been used to supply electricity, with most burned at coal-fired power plants. Coal gasification is a newer thermo-chemical process in which the gasifier’s heat and pressure break down coal into basic chemical components and turn it into a synthetic natural gas called syngas.  While syngas can be produced from many other sources such as…

Renewable Natural Gas Expert

What does a renewable natural gas expert or consultant do? Renewable natural gas (RNG) also called biomethane is produced from biogas derived from renewable resources or biomass materials.  The biogas is cleaned, scrubbed, and treated to remove carbon dioxide, hydrogen sulfide, and other impurities to make it suitable as a natural gas replacement that can…

Tire and Rubber Recycling

Disposing of tires has historically been very challenging due to the worldwide volume, rubber’s robust durability, and the ecological implications of tires in landfills. In years past, billions of tires historically filled landfills, yet as of 2015, less than 75 million tires remain in U.S. stockpiles. The European Union has done an outstanding job of…

Microbial Fermentation

Microbial Fermentation is the growth of a microorganism, usually a bacterium, yeast, or filamentous fungus in a liquid medium to transform one material into another using the microbe’s metabolism as the manufacturing process to result in a commercial product.  That product can be microbial cell mass, a product contained within the microbe, or a product…

Biofuels Consultant

The term “biofuels” refers to a fuel produced through a mainstream biological process like agriculture (as opposed to fuels which are produced through a geological process like coal or petroleum). Biofuels are normally derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes. Biodiesel and ethanol are two examples of biofuels.  Biofuels are…

Bioenergy Project Funding

Can we identify the key reasons that many bioenergy projects fail to get funding?  Yes.  Is there a “magic bullet” that guarantees funding of a bioenergy project?  No, but a review of the common characteristics of those that fail to receive funding is not difficult, and once understood, provides a pathway to the best chance…

Pyrolysis Reactor Design

Pyrolysis reactors are often custom-engineered due to multitude of variables that impact the design process.  Economic factors such as feedstock selection, targeted end products, capacity, and build site limitations all need to be considered in selection of a particular reactor design.  Additionally, primary technical considerations include biomass particle size, operating temperature, solid and gas residence…
