Waste-to-Energy Carbon Capture study for Westenergy, Finland

Waste-to-Energy carbon capture: a techno-economic study

Westenergy own and operate a modern Waste-to-Energy (WtE) plant in the west of Finland. They wanted to know how a WtE plant could work as a carbon sink and how the different carbon capture systems complement the existing process.

AFRY were able to leverage their extensive WtE experience and 10+ years of expert understanding of CCUS technologies to deliver a techo-economic study of 4 different carbon capture technologies which included:

  • Power plant model
  • Simulation of generalized capture models for each technology and assessment of impact on Plant
  • Budget enquires to process licensors and generation of models with their KPIs (Key Performance Indicators)
  • CAPEX and OPEX estimates and levelized cost of capture
  • Preparation of evaluation model to rank the technologies.

The conclusion provided Westenergy with a firm understanding of the technologies, their features, risks and maturity whilst also assessing the impact on the WtE plant’s power and heat sales.
