Waste-to-Energy Embraces CCS and BECCS

Why It Matters

These projects prove that coupling carbon capture with waste‑to‑energy can transform a high‑emission sector into a net carbon sink, creating new revenue from carbon credits and helping nations meet climate commitments.

Key Takeaways

• Protos ERF to capture 370k t CO₂ annually.
• AtmosClear BECCS targets 680k t biogenic CO₂ per year.
• Copenhagen plans BECCS at Amagerværket, supporting climate‑positive goal.
• KEZO pilot tests 90% capture with hot potassium carbonate.
• Projects illustrate global shift to carbon‑negative waste energy.

Pulse Analysis

The UK’s Protos Energy Recovery Facility marks a watershed moment for waste‑to‑energy (WtE) operators. By installing a two‑line amine‑scrubbing system, Kanadevia Inova will sequester roughly 370,000 tonnes of CO₂ each year, a blend of biogenic and fossil sources. The captured stream will be stored in depleted gas reservoirs under Liverpool Bay, effectively turning the plant into a net negative emitter. This initiative not only satisfies tightening UK emissions regulations but also creates a replicable template for other WtE sites seeking to monetize carbon‑negative performance.

Across the Atlantic, AtmosClear’s BECCS project in Baton Rouge leverages ExxonMobil’s extensive CCS infrastructure to transport and permanently store up to 680,000 tonnes of biogenic CO₂ annually. The partnership delivers high‑integrity carbon‑removal (CDR) credits, already contracted to Microsoft under one of the largest purchase agreements to date. By coupling biomass combustion with proven capture technology, the facility generates clean power while providing a scalable source of verified emissions reductions, illustrating how corporate demand for CDR can accelerate commercial BECCS deployment.

Europe is simultaneously diversifying capture approaches. Copenhagen’s HOFOR and Drax subsidiary Elimini are developing a BECCS retrofit for the Amagerværket CHP plant, aiming to remove hundreds of thousands of tonnes of CO₂ and support Denmark’s climate‑positive 2035 goal. In Switzerland, KEZO’s pilot with CATACARB’s hot potassium carbonate solvent demonstrates 90 % capture efficiency under variable waste‑feed conditions, offering a lower‑energy alternative to traditional amines. Together, these projects highlight a global policy push—exemplified by Denmark’s $4.2 bn CCS fund—and signal that the waste‑energy sector is rapidly evolving into a cornerstone of net‑zero strategies.
