Westenergy has developed a carbon capture project to produce 200,000 t/a CO2 for the synthesis of e-methanol. This project follows the company's vision that WtE plants can be a sustainable carbon source in the circular economy. The presentation will introduce the developed technical solution of the amine-based carbon capture and liquefaction plant and how it is integrated into the waste-to-energy plant. It will show how the challenging goal of minimising energy consumption, providing district heating and producing high-quality CO2 can be achieved. The practical experiences from the design process of a CO2 capture plant from the owner's point of view are discussed, as well as the regulatory and commercial issues related to the business models of utilising captured CO2 in the EU market.
