Poet sues Andritz over failed 2G feedstock pretreatment system

In Iowa, Poet Design & Construction Inc. is suing Andritz Inc. for breach of contract and professional negligence after investing $25 million in a feedstock pretreatment system Andritz designed but was never able to produce the intermediates required for cellulosic ethanol production, despite 1.5 years of redesigns and multiple plant shut downs. Poet claims the design failures have kept it from producing cellulosic ethanol at commercial scale. It first advised the company there were problems with the system as far back as 2014.
