ORC in Waste-to-Energy Plants: Recovering the Heat No One Uses
ORC Waste To Energy
A waste-to-energy plant converts waste into power, but even an efficient plant rejects a large share of its heat through flue gas and cooling. An organic Rankine cycle (ORC) system sits downstream of that loss, capturing low-to-medium temperature heat that would otherwise be dumped and turning it into additional electricity.
Where the Heat Comes From
In a thermal waste-to-energy plant, heat leaves the process at several points: in the flue gas from combustion or gasification, in the syngas cooling train, and in the steam cycle’s own condenser. Each of these streams is too cool for a conventional steam turbine but hot enough to boil an ORC working fluid, so stacking an ORC onto those streams converts waste heat into extra megawatts.
Why It Improves the Plant
Waste-to-energy economics are tight, and every recovered megawatt improves them directly. Adding ORC lifts the plant’s overall efficiency, increases power output from the same feedstock, and reduces the heat rejected to the environment, all without changing the core process. It is one of the clearest retrofit wins available to an operating or planned WtE facility.

Turn Waste Heat Into Megawatts
Klean Industries integrates ORC power recovery into its turn-key waste-to-energy systems, boosting output from heat the process otherwise rejects.
Klean Industries has delivered three recovered carbon black plants in India over the past two years, with a further five under letter of intent.
