JFE Engineering Corporation (President and CEO: Hajime Oshita; Head office location: Chiyoda, Tokyo) has started verification test to assess the viability of the CCU (carbon capture and utilization) process, which would capture and utilize CO2 from wase-to-energy (WtE) facility emission gas. The test will be conducted at Clean Plaza Fujimi*1, a WtE facility constructed by the cities of Mitaka and Chofu, until the end of 2022.
By implementing JFE's proposed CO2 capturing technology, WtE facilities will be able achieve "negative carbon emission" (i.e., more CO2 captured than emitted) by considering the environmental impact given from the biomass*2 composition contained in the treated waste.
The applied CO2 capturing technology at Clean Plaza Fujimi will be amine adsorption process, a proven process utilized in the construction of natural gas plants. Development of membrane separation process is also underway, and is anticipated to produce higher capturing efficiency, with possible applications apart from WtE facilities.
In addition to CO2 capturing, JFE is also planning to conduct various field tests to evaluate the viability of CO2 chemical recycling technologies. For example, having CO2 react with hydrogen would produce methane (CH4), which can be used as fuel in the form of methane gas. And there has been growing attention regarding the gas-to-liquid conversion of methanol (CH3OH) - a base material for many chemical products - at normal temperatures and pressures, a process that would make methanol easier to store, transport, and use. This technology has been positioned as a new R&D field, and JFE will accelerate research in this area.
JFE possesses numerous technologies to contribute prevention of global warming. Looking at EPC (engineering, procurement, and construction) for the construction of WtE facilities in particular, the company has established technologies to reduce the emission of greenhouse gases through innovations, such as super-efficient power generation and fully-automated plant operation.
Hereafter, "CCU-readiness" will be JFE's standard for WtE facilities, and together with the proposal of best CO2 capturing technology which would suits with client's condition, JFE will keep contributing to the realization of low-carbon society.
- *1 Clean Plaza Fujimi is a WtE facility maintained by the Fujimi Hygiene Association (7-50-30 Jindaiji Higashimachi, Chofu, Tokyo), established by the cities of Mitaka and Chofu. EPC duties were performed by JFE, who is also responsible for operation & maintenance of the facility for a duration of twenty years.
- *2 The biomass contained in waste is deemed to be carbon neutral.
