Kanadevia has completed a demonstration facility at the Shinagawa Waste Treatment Plant to concentrate and recover CO2 from flue gas generated by waste incineration. The technology is considered the world's first of its kind, and validation is progressing as an initiative to support municipal decarbonisation, with commercialisation targeted for 2031.
Kanadevia held a completion ceremony on the 5th and established a demonstration facility at the Shinagawa Waste Treatment Plant to concentrate and recover CO2 from flue gas generated by waste incineration. The project was selected for support under an NEDO programme, and the total project cost is approximately ¥19.2 billion. The company has stated that it aims to commercialise the technology in 2031.
The key technology involves returning the flue gas to the incinerator once, adding oxygen and combusting it to increase the CO2 concentration, then separating and recovering the CO2 with a solid adsorbent. The target recovery rate is 90% or more, and the maximum recovery concentration is expected to reach 30-60%. The current policy is to improve the recovery rate by suppressing factors that cause it to decline.
The facility is designed to process 2 tonnes of waste per day, with validation to be conducted through FY2027 to enable stable recovery of 90% or more of the CO2. The company aims to make the facility more compact than conventional methods using liquid amines, so that it can be more readily introduced by municipalities with limited site area.
The company is also considering ways to use some of the recovered CO2 for industrial applications. Under the plan, the facility will be expanded tenfold from FY2028 onward, with commercialisation targeted thereafter. Cost reductions and effective use of CO2 are cited as prerequisites for securing economic viability.
