Kanadevia Corporation Launches Groundbreaking CO₂ Capture Technology for Waste-to-Energy
Tokyo, Japan – Kanadevia Corporation (TOKYO:7004) has initiated a significant project to develop high-concentration CO₂ waste incineration technology, starting from fiscal year 2024. The objective of this project is to capture and separate carbon dioxide (CO₂) from the emissions produced during waste incineration. In a major step forward, the company plans to conduct one of the first demonstrations of this technology at the Shinagawa Incineration Plant in Tokyo, scheduled for November 2026.
The demonstration aims to showcase an innovative method for efficiently capturing CO₂ from waste incineration emissions. This pilot facility will feature an incinerator designed to handle 2 tons of waste per day, along with a specialized system for separating and capturing CO₂. By using oxygen and recycled flue gas instead of regular combustion air, this advanced process is expected to increase the CO₂ concentration in the emissions to levels significantly higher than those found in typical waste incineration systems. This project is set to extend through fiscal year 2030.
Currently, traditional waste-to-energy (WtE) plants do not separate or recover CO₂ from their emissions. In these conventional systems, the CO₂ concentration typically ranges from about 8% to 15%. The new technology aims to elevate this concentration to between 30% and 60%, enhancing the efficiency of CO₂ capture regardless of the methods used. This captured CO₂ could be transformed into liquid form or utilized as a feedstock for creating synthetic fuels, allowing WtE facilities to implement a circular carbon economy and potentially function as carbon-neutral plants.
Notably, this new approach is anticipated to reduce the volume of emissions sent to CO₂ capture facilities to a small fraction of what is currently seen in traditional methods. Consequently, the space required for CO₂ capture equipment will also decrease when compared to simply adding such systems to existing WtE plants.
Laboratory tests have already indicated that this technology can achieve over 90% CO₂ recovery rates with a purity exceeding 95%. The ultimate goal is to maintain a stable capture rate exceeding 90% from emissions with high CO₂ content.
Once fully commercialized, this technology will not only generate electricity through waste incineration but will also enable facilities to capture CO₂ for reuse as a resource in fuel production.
Project Overview:
- Location: Shinagawa Incineration Plant, Clean Authority of Tokyo (Shinagawa City, Tokyo)
- Facility Capacity: Incinerator processing 2 tons of waste per day
- Demonstration Period: November 2026 to March 2028
This innovative step by Kanadevia Corporation marks an exciting development in the waste-to-energy sector, paving the way for greener technologies and a more sustainable future.
