Waste incineration and energy recovery systems
Organic and hazardous waste incineration engineered around three outputs: bottom ash, treated flue gas and heat you can actually use.
Overview
Overview
Incineration is the treatment of last resort and, handled properly, the point at which a waste stream stops being purely a cost. Glorinda supplies incineration systems for organic and hazardous waste, engineered around three outputs that all have to be managed deliberately: bottom ash, treated flue gas, and recoverable heat.
The engineering question is rarely "can this be burned". It is what the combustion conditions have to be for this specific waste, what the flue gas train needs to remove to meet the permit, what happens to the ash, and whether the heat has a use on site. Answer those four and the commercial case usually resolves itself.
Detail
The three outputs
Incinerator bottom ash
Collected and handled through a dedicated bottom-ash handling system. Volume and character depend directly on the feed, which is why characterisation comes first.
Treated flue gas and particles
Cleaned before release through a flue gas treatment system sized against the specific contaminants present and the emission limits that apply.
Heat energy
Available for recovery as steam, hot water or electricity. Whether it is worth recovering depends on what the site can absorb — and that is a process question, not an equipment question.
Detail
Combined cycle on municipal solid waste
Where the fuel is municipal solid waste, a higher-efficiency configuration is available. The 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 power, operating on municipal solid waste fuel at a higher pressure and lower temperature than other fuels would allow.
Ahead of this, our waste separation technology processes both selected and unsorted municipal waste downstream of mechanical treatment. A mechanochemical micronization process alters the molecular structure of the material, making it available for combustion and contributing to its stabilisation and sanitation. The plant can be installed downstream of the shredding system or supplied as a mobile unit.

Detail
Hazardous area compliance
Glorinda's incinerator packages are designed for use in hazardous zones — Zone 1 and Zone 2 — and are compatible with gas groups IIA, IIB and IIC. Where the surrounding process area is classified, that classification has to be designed into the package from the start rather than accommodated afterwards.
Continuous emission monitoring is available as part of the same scope through our analyzer and metering systems, including CEMS analysers, sampling systems, shelters and the data analysis and reporting that permits normally require.
Applications
Applications and challenges
Where it applies
- Hazardous industrial waste requiring permitted thermal destruction
- Municipal solid waste with energy recovery
- Dewatered and dried sewage or industrial sludge
- Solid output from a ZLD line at around 70% w/w concentration, fired with a backup fuel
- Process residues with calorific value and no disposal route
- Waste-derived fuel for industrial boilers
Common challenges we are asked to solve
- Emission limits the existing plant cannot meet
- Ash classified as hazardous and expensive to move
- Heat leaving the stack that a neighbouring process could use
- Feed variability upsetting combustion and emissions
- A classified hazardous area around the intended location
- Permit conditions requiring continuous emission monitoring
FAQ
Frequently asked questions
What waste can you incinerate?
Organic industrial waste and hazardous waste in solid, liquid, gaseous and mixed form. The determining factors are calorific value, moisture, and the contaminants the flue gas train has to remove — all of which come out of characterisation.
Is the incinerator suitable for a classified area?
Yes. Packages are designed for hazardous zones Zone 1 and Zone 2 and are compatible with gas groups IIA, IIB and IIC.
Can I burn ZLD solids?
Often, yes. Solid output from a ZLD process at approximately 70% w/w concentration can be incinerated using a backup fuel such as wood waste, bagasse or other organic residues in a standard boiler, serving as an energy source. Whether that is the right route depends on what else the solid could be — compost, fertiliser, animal feed or recovered salt are all better outcomes where the feed allows.
Do you supply the emission monitoring?
Yes, as part of the same scope. CEMS and AQMS packages including analysers, sampling systems, shelters and reporting software are part of our analyzer and metering product line.
