Technology
Robust combustion. Controlled emissions. Useful energy.
Why rotary kiln?
Rotary kilns are robust for diverse, difficult wastes (including high-chlorine or acidic streams) because they provide excellent mixing, controlled residence time and stable combustion conditions – enabling high destruction efficiencies with integrated flue-gas cleaning.
How it works
Process summary
- Receipt & segregation – secure transfer, quarantine, and acceptance checks; barcode traceability and load tracking
- Feed & primary combustion (rotary kiln) – waste is charged to a rotating kiln that provides mixing and residence time to ensure complete combustion of solids and liquids
- Secondary combustion & residence – combustion gases pass to a secondary chamber (afterburner) ensuring required temperatures and residence times for destruction of organics
- Flue gas cleaning – multi-stage cleaning (e.g., sorbent injection, ceramic filters, De-NOx units) to meet permit limits; MCERTS continuous monitoring for key pollutants
- Energy recovery – heat exchangers recover thermal energy as steam for on-site use and for power generation to meet on-site demand and grid injection
- Residuals handling – bottom ash and residues are tested, treated and disposed/recovered in accordance with regulatory guidance

FAQs
Is incineration safe?
When designed and operated to permit standards – with modern rotary kilns, secondary combustion and multi-stage flue-gas abatement plus continuous monitoring – incineration achieves secure destruction and low emissions. Independent monitoring and permitting form the backbone of safety and compliance.
