| Technology Brief | Company API was acquird by Brazil's GranBio in 2019. The plant — which began as a pilot operation to produce bioethanol from the waste discharged by DPI — received a $22 million U.S. Department of Energy grant with funds coming from the American Recovery and Reinvestment Act in 2008. Construction began in 2011 and operations initiated in 2012, but things began to go south from there, as large renovations were needed to correct waste processing issues. The first batch of cellulosic ethanol wasn’t shipped until 2014. In 2021, the plant produces wood molasses, used to manufacture feed pellets for livestock. |
