American Process International LLC (API) is a combined biotechnology and engineering company. API was founded by Dr. Theodora Retsina, who graduated from Imperial College, London, with a PhD in Chemical Engineering in 1994 as an engineering consulting company serving the forest products industry. API has completed over 500 energy and water integration studies and identified annual energy savings opportunities of over one billion dollars. API boasts the world’s largest experience list for the application of Pinch technology to industry.

Since 2005, the company has been developing technologies for the conversion of biomass into cellulosic sugars to be used in the production of biofuels and biobased chemicals. American Process owns two patented cellulosic technologies, Green Power+® and AVAP®.
Our GreenPower+® technology produces low cost cellulosic sugars by extracting only hemicelluloses from biomass. The rest of the biomass is used downstream for the production of renewable power, pellets, wood or pulp products. The technology is feedstock agnostic, and can work with hardwood, softwood, bagasse and other agricultural residue.

Our AVAP® technology produces low cost pure cellulosic sugars by converting all the cellulose and hemicelluloses of biomass to cellulosic sugars. These sugars can then be converted or fermented by bacteria or yeast in to bio-based chemicals and biofuels.

Furthermore, we have developed a single, cost-effective IP protected process for production of cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF) along with novel, hydrophobic, lignin coated versions of each. With our AVAP® Biorefinery pretreatment technology, these cellulose nanomaterials are produced from woody or non-woody biomass at a fraction of the cost for competing nanocellulose production processes.

Our Company envisions the development of a sustainable global economy where “Sugar is the New Crude ®”.
