History

Theodora Retsina

American Process Inc., (API) was founded by Theodora Retsina in 1995 as an engineering consulting company in the forest products industry.

Since then, API has completed over 500 energy integration studies and projects within the industry and identified annual energy savings opportunities of billions of dollars.

API has an experienced management team that has been working together for more than a decade, having 100 years of collective background in biomass chemistry and fractionation, process integration, energy production and conservation, and project execution and operations. This expertise covers the biotechnology, pulp and paper, and energy sectors.

In 2005 API began to self-fund R&D on biomass-derived sugar technology. The company has successfully developed two technologies for biomass-derived cellulosic sugar and ethanol, GreenPower+® and AVAP®.

The construction of the demonstration plant for GreenPower+ technology – Alpena Biorefinery - started in 2011 and the plant started up the second quarter of 2012. In 2014 Alpena biorefinery hit big milestone by selling the first Cellulosic Ethanol RINs in the USA.

In 2013 API celebrated the startup of the second demonstration plant for AVAP technology – AVAPCO/Thomaston Biorefinery - with a 1 ton/day cellulosic sugars production.

On April 2013, American Process had the honor to welcome GranBio into its family. GranBio, a 100% Brazilian pioneer in biorefinery technologies, completed the acquisition of a 25% equity investment.

In the third quarter of 2014, API announced the lab scale production of the advanced innovative material: Nanocellulose Fibrils and Crystals and in first quarter of 2015 trademarked the name BioPlus® and L – BioPlus®.

BioPlus® Nanocellulose pre commercial production started on April 2015, at Thomaston Biorefinery’s ½ ton/d pilot plant.
