Waste to Energy
Turn your WtE stack into a value stream. With Galloxol® CO₂ capture (and Hybrisol® where biogenic gas upgrading is present), plants reduce emissions near residential areas and route CO₂ to local users, liquid sales, or permanent storage with credits.
How It Works
Step-by-step
Handle variable WtE flue gas without disrupting power/heat export. This sequence conditions the stream, captures/polishes CO₂ under load swings, smooths outages with buffers and offers site logistics via liquefaction.
Source the CO₂ (WtE boiler/HRSG)
We route CO₂-containing flue gas from the WtE boiler/HRSG into the capture train. The inlet is sized to real duty and ash/acid-gas load to keep downstream stable.
Quench & condense (dust/acid control + energy recovery)
Rapid quench lowers temperature; condensers remove moisture and acid vapour. Demisters cut droplets/dust and recovered heat can pre-warm combustion air or district-heating loops.
Capture & polish (run under load swings)
Galloxol® captures CO₂ efficiently under variable loads. Product is dried and trimmed (low O₂, low total hydrocarbons as CH₄, particle-free) to meet industrial/food-grade targets where required.
Buffer storage (ride through tipping/maintenance windows)
Gas buffers smooth feed variability, outages and flue-gas upsets. Inline analysers and automatic divert protect quality; logs support permits and audits.
(Optional) Liquefaction & site logistics
Liquefy for compact storage and easy transfers across large sites. Insulated tanks minimise footprint and let capture operate steadily while offtake varies.
Distribute & valorise
Send CO₂ to internal users or regional partners (materials carbonation, greenhouses, e-fuels) or load to tankers. Turning a liability into value supports WtE sustainability KPIs.

Yield impact
Up to ~90–90% CO₂ capture (project-set target)
Capture yield is set in design and tuned to your heat/power balance. HIGH-temp enables the highest capture at strong energy efficiency, while LOW-temp reuses heat for stable, low-volatility OPEX; we model stack flow/CO₂%, available heat and outlets to give a capture-vs-energy curve so you can choose the optimal %.
Each extra capture point ≈ 1:1 scope-1 abatement and more product for sales or storage credits. Product is ≥99% CO₂ with very low moisture, and per-stream metering/QA provides audit-ready proof; the final rate is site-specific and agreed at FEED, with €/t trade-offs shown.

Benefits
Benefits of Galloxol® in Waste to energy
Turn stack CO₂ into a metered product stream that lowers reported emissions and creates value. For WtE sites near communities, the package is compact, quiet and safe; outlets include local pipeline, liquid sales, and permanent storage where frameworks exist. QA and per-stream metering keep billing and credit claims straightforward.
Designed for dense, urban footprints
Compact skids, enclosure options and acoustic treatments keep noise and visual impact within neighbourhood expectations. Intake/exhaust placement and shielded lines reduce line-of-sight propagation.
Access, walkways and lifting routes are planned so maintenance can happen inside normal outage windows, no heroic scaffolding or road closures.
We provide siting layouts that consider line-of-sight noise, air inlets/outlets, and screening so the package blends with existing buildings. Access, walkways and craning are planned during design, so both installation and future maintenance remain routine, and so local stakeholders see a tidy, well-managed asset from day one.
Diversified revenue beyond heat & power
Balance pipeline sales, liquid offtake and storage credits so income isn’t tied to a single buyer or season. Per-stream meters and batch QA certificates support firm pricing and reduce disputes.
Buffers are sized for your loading rhythm (daily/weekly draws) so tanker dispatch and pipeline nominations run smoothly.
We’ll model the outlet mix (pipe/liquid/storage) against your geography, buyer base and gate schedule to avoid single-buyer dependence. Each outlet is metered and QA’d (purity, moisture, timestamps), which supports firmer pricing, simpler invoicing, and faster dispute resolution with offtakers and registries.
Safety & quality without solvent carry-over
With no vapour phase, the solvent stays in the loop, no entrainment into product CO₂ or surroundings. Product is engineered to ≥99% CO₂ with very low moisture to protect downstream users and simplify audits.
Clean, dry CO₂ also reduces icing and fouling in compressors and heat-exchange hardware downstream.
Because the solvent has no vapour phase, there’s no solvent entrainment into product CO₂ or the surroundings under normal operation. That simplifies your safety case and permitting, and it also protects downstream equipment from fouling, meaning fewer unplanned clean-downs in compressors, exchangers and liquefaction hardware.
Energy-aware by design
HIGH-temp maximises capture and energy efficiency via deeper heat recovery; LOW-temp reuses low-grade or renewable heat already on site, reducing exposure to electricity price swings.
Sensible compression ratios keep specific energy per tonne predictable, which stabilises €/t across seasons.
With HIGH-temp you prioritise capture and heat efficiency via deeper integration; with LOW-temp you reuse low-grade/renewable heat you already have, reducing exposure to electricity volatility. In both cases, sensible compression ratios keep specific energy per tonne predictable for finance and operations.
Straightforward operation & maintenance
Modest conditions limit wear on rotating equipment; interlocks between buffer, compressors and outlets make starts/stops repeatable. Standardised SOPs, spares and HMIs reduce training time.
Remote telemetry hooks and alarm classes help your control room oversee capture alongside the boiler/HRSG with minimal extra headcount.
Interlocks between buffer, compressors and outlets make starts/stops repeatable, while standard HMIs and alarm classes align with the way your control room already works. A clear PM schedule and spares list keep planned outages short; remote telemetry hooks help trend performance without adding headcount.

All frequently asked questionsYes. The capture loop uses Galloxol®, a non-hazardous solvent that does not enter a vapour phase, so there is no solvent entrainment to air or product CO₂. Packages include acoustic treatments, enclosures and screening suitable for neighbourhood plots. For permitting, we supply HAZOP/LOPA (site-dependent) and environmental notes aligned with urban standards, plus startup/shutdown procedures to slot into your HSE system.
The tie-in is post-APC and operates at modest pressure/temperature, so the incineration/steam cycle remains the driver for heat and power. Feed conditioning and a small CO₂ buffer prevent capture trips from propagating upstream. In practice, you maintain heat service while converting stack CO₂ into a metered product you can sell or store.
Not necessarily. Many WtE sites start with local pipeline sales and add a liquefier when volumes and offtake contracts justify the CAPEX. We design tie-ins and hours-of-cover so a liquefier can drop in later with a short outage, reusing the same metering/QA chain for clean invoicing.
Where a storage partner and recognised framework exist, routing a portion of captured CO₂ to permanent storage can generate credits. We provide metered splits, QA certificates and automated mass-balance so your MRV package is audit-ready. Sales to local industry and storage for credits can run in parallel without complicating day-to-day operations.
Trains are modular skids with compact footprints. We plan service clearances, walkways and craning routes up front, and specify silencers/enclosures based on local noise limits. Equipment placement and screening reduce line-of-sight propagation, keeping neighbourhood impact low and easing approvals.
Most buyers ask for ≥99% CO₂ with very low moisture. Inline instrumentation logs purity/moisture with timestamps, producing batch or allocation certificates for each outlet. Clean, dry CO₂ protects downstream equipment, shortens audits, and supports food-adjacent or industrial users that demand consistency.
Operating cost is driven mainly by regeneration heat and compression. Heat integration plus sensible pressure ratios stabilise energy per tonne. Choosing HIGH-temp vs LOW-temp lets you balance capture efficiency with the opportunity to reuse low-grade heat already on site, keeping €/t stable across seasons.
Yes. If your hub also digests organics, Hybrisol® upgrades biogas to biomethane, and the captured CO₂ from either line can share the same pipeline, liquefaction or storage outlets. Metering and QA are per stream, so contracts and claims remain straightforward.
