Earth Energy's technology is a hybrid biological/chemical process. The biological step is the same process that occurs in the rumen of cattle, termite guts, or methanogenic anaerobic digesters where  a mixed culture of naturally occurring microorganisms converts biomass into carboxylic acids (i.e., short- and medium-chain fatty acids such as acetic, propionic, butyric, valeric, caproic, heptanoic and octanoic acids).  These carboxylic acids are recovered using patented and proprietary technologies, which may then be chemically converted into other desired products. 

The advantages of Earth Energy's fermentation process are as follows:

  • Thermodynamically favored

  • Non-sterile; aseptic conditions are not required

  • Only natural cultures are used; no GMO's

  • No extraneous enzymes are needed

  • High yields (theoretical yields expressed in ethanol equivalents exceed 130 gal/dry ton)

  • Ultra-feedstock agnostic; can process cellulose, hemicellulose, proteins, fats, pectin, chitin, etc with little differentiation

The advantages of Earth Energy's acid extraction process are as follows:
  • Simple, efficient and effective

  • Uses no extraneous solvents

  • Produces very pure acids without complex or expensive purification techniques

  • High product recovery
