Sysav waste facility pursues net zero

By introducing carbon capture and storage, Sysav aims to reduce carbon emissions from its waste-to-energy plant by approximately 90%. Capturing and storing Sysav’s carbon emissions represents an important step towards achieving negative emissions in Sweden.

Ramboll contributed to Sysav’s vision by conducting a feasibility study for a full-scale carbon capture solution for the plant with a capacity of approximately 500,000 tonnes CO2 per year. The Swedish Energy Agency’s climate initiative “Industriklivet” partly funded the feasibility study.

The feasibility study aimed to identify the most advantageous technology choices for carbon capture, processing, and energy integration, while also exploring important design adjustments to develop a unified value chain at the waste-to-energy plant. In addition, Ramboll also investigated the total economic aspects of establishing and commissioning CO2 capture, transport, and final storage.

As a result of this rigorous screening, two technologies were identified as the most suitable for Sysav: an amine-based technique with Sysav carbon capture (MEA) solution and a Hot Potassium Carbonate (HPC) solution were identified as the two most promising technologies.

A comprehensive economic and legal analysis was carried out, which included the overall economic consequences of establishing and commissioning a potential carbon capture plant and an assessment of the regulatory conditions with the purpose of assessing whether Sweden’s legislation supports the use of carbon capture in Sweden.
