Waste Incineration Plant at Saga City :Phase 1: CO2 utilization in agriculture（deployment in small scale）
 Project promoted by Saga city as part of its Biomass Industrial City Vision. CO2 is captured fromexhaust gas of existing Saga city municipal waste incineration (WtE; Waste to Energy) plant.
 First phase of the project started in 2013 until 2015. Using the small scale demo skid, the conceptof capturing high purity CO2 from WtE was proven through cumulative 8000 hours of operation.
