Waste incineration with energy recovery
Combustion designed as a generation project rather than a disposal one — with separation upstream and a combined cycle downstream.
Overview
Overview
This page covers incineration approached as an energy project. Where the emphasis is on compliant destruction of hazardous or industrial waste, the environment-side incineration page covers that scope — the same equipment, a different starting question.
The energy-first question is how much useful output the waste can be made to yield. That is answered in three places: the separation stage that conditions the fuel, the combustion and heat recovery configuration, and whether the site can absorb heat as well as power.
Detail
Conditioning the fuel
Our waste separation technology works with both selected waste and unsorted municipal waste, downstream of mechanical treatment, through a mechanochemical process that alters its molecular structure by micronization. That makes the waste available for combustion and contributes to its stabilisation and sanitation.
The plant can be located downstream of the shredding system, or supplied as a mobile unit where the volume does not justify a fixed installation.
Detail
Combined cycle on municipal solid waste
In the high-efficiency configuration, municipal solid waste serves as the primary fuel source for a turbine or gas engine. The flue gas recovered from that turbine or engine is then used to superheat the steam entering the water turbine or the general water supply system.
The result is a combined cycle power plant, or cogeneration of heat and energy, that uses municipal solid waste fuel at a higher pressure and lower temperature than other fuels.
The three outputs still have to be engineered: incinerator bottom ash, treated flue gas and particles cleaned before release, and heat energy for recovery.

The generation end
Waste-to-energy is one of the listed applications for Glorinda steam turbines, which run from 50 kW to 180 MW across back-pressure, condensing and extraction configurations. Where the duty is 3 to 10 MW and simplicity matters more than absolute efficiency, our energy recovery systems provide a direct-drive, gearbox-free machine on a common base frame with anti-vibration mounts, which can be installed without extensive civil work.
The water and steam side is engineered alongside it — demineralised water, boiler feed treatment and condensate polishing, covered on the utility water page.
Applications
Applications and challenges
Where it applies
- Municipal solid waste energy recovery

- No heat customer within economic distance
- Ash handling and its wastewater becoming a second problem
- Turbine sized before the steam conditions were settled
FAQ
Frequently asked questions
How is this different from your waste management incineration page?
Same equipment, different starting question. The waste management page approaches incineration as compliant destruction of hazardous and industrial waste. This page approaches it as a generation project, where the objective is maximum useful output.
What makes the combined cycle configuration efficient?
Municipal solid waste fires a turbine or gas engine as the primary fuel, and the flue gas recovered from it superheats the steam entering the water turbine. That gives combined cycle power or CHP on waste fuel at a higher pressure and lower temperature than other fuels.
Do we need a heat customer to make it work?
Not necessarily, but it changes the economics substantially. Power-only recovery works; CHP works better. The distance to a credible heat customer is one of the first things we check in a feasibility study.
Can you retrofit heat recovery to an existing incinerator?
Often yes, and it is usually the cheapest megawatt on the site. The constraints are the existing flue gas train, available space, and whether the plant can accept the outage needed to install it.
