Waste heat was always money; with allowances at €80.01/t it's now two revenue streams. This page is the economics — for the technology-by-temperature guide see heat recovery systems.
US DOE: 20–50% of industrial energy input becomes waste heat. EU studies (Heat Roadmap Europe) estimate ~300 TWh/yr of recoverable industrial waste heat in Europe alone — roughly the heat demand of 25 million homes. At plant level, audits routinely find 5–15% of fuel recoverable with paybacks under 3 years.
| Component | Value per MWh recovered | Note |
|---|---|---|
| Fuel saving (gas @ ~€40/MWh) | ≈€40–45 | every MWh not burned |
| CO2 saving (0.2 t × €80.01) | ≈€16 | at full payable share (2034: 100%) |
| Total at 2034 rules | ≈€55–60/MWh | vs ≈€40 in the pre-ETS world |
Indicative at mid-2026 EU gas prices; your fuel contract sets the exact figure. The point is structural: the carbon term grows every year to 2034 on the official schedule.
Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes Inzonex Modular Insulation — snap-fastened modules engineered per temperature tier, not generic off-the-shelf jackets:
Every tonne you stop emitting is a tonne you don't have to report: cutting heat loss is a measurable, auditable Scope 1 reduction that flows straight into EU ETS, CBAM and your ESG / CSRD disclosures — not an offset, an actual emission cut.
A recovery project rejected at €20/MWh value in 2020 is worth ≈€55–60/MWh by 2034 rules — the IRR roughly doubles with no engineering change. Finance teams re-screening their old efficiency studies against the 2026–2034 payable-share schedule are finding approved projects in the reject pile.
1) Eliminate losses with insulation (≤€0/t — see Scope 1), 2) recover what process chemistry must reject, 3) upgrade the remainder with heat pumps. Start with the free plant study — it ranks your equipment by recoverable loss.
