Decarbonizing Waste-to-Energy
with fully electric CO₂ Capture
Turning waste into clean energy - and climate action
Waste-to-Energy (WtE) facilities play a crucial role in managing municipal solid waste while generating electricity and heat. When combined with carbon capture, WtE plants can create negative emissions as the waste contains a substantial amount of carbon which is naturally part of the carbon cycle, and deliver sustainable waste management.
Capsol Technologies offers cost-efficient, fully electric CO₂ capture solutions designed for seamless integration into WtE operations, enabling plants to meet climate targets while continuing to provide essential services to communities.
Why Capsol Technologies for Waste-to-Energy?
✓ Fully electric and steam-free operation - perfect for plants with limited or no excess steam
✓ Low operating costs - through efficient heat recuperation and mechanical vapor recompression (MVR)
✓ Well-proven solven technology - hot potassium carbonate (HPC), used commercially for decades
✓ Compatible with distric heating - captures CO₂ while preserving heat for local grids
✓ Flexible, scalable solutions - from pilot to full-scale deployment
Proven technology, adapted for Waste-to-Energy
Capsol’s technology platform uses HPC - a stable, non-toxic solvent - to capture CO₂ from WtE flue gases efficiently. Our CapsolEoP® (End-of-Pipe) solution is particularly suited for WtE plants because it combines high performance with low dependency on plant steam.
How it Works:
✓ Flue gas is compressed to 5-10 bar
✓ Heat from flue gas is recuperated to reduce energy demand
✓ The cleaned flue gas is expanded to recover compression power
✓ CO₂ is absorbed in a packed column by the HPC solvent
✓ The CO₂-rich solvent is regenerated at atmospheric pressure using heat supplied by MVR systems
All required heat is provided electrically, eliminating the need for additional steam from the plant.
