We are happy to announce that we will be bringing ABC’s Digester Operator Training series to ABC’s annual conference, BIOGAS AMERICAS 2020. This unique course module will pair intensive classroom training with a unique look at equipment. This training is designed specifically for operators and owners in charge of operations. A separate class, AD Business School, designed for project developers, will be available on June 23 at the conference.
