In 2014, UTC was tasked with effectively resolving the issue of disposing of grain and molasses stillage effluent. This involved daily peak organic loads and high concentrations of suspended solids, with COD at 30,000 mg O₂/L and BOD. As a result, an anaerobic treatment system was implemented to produce biogas. The system is based on two high-load UASB reactors. The COD removal rate is 85%. Biogas production is 230 m³ per hour. The treatment system has been operating continuously and has been handling peak loads since 2014.
