Modular Waste-to-Energy
County-level waste-to-energy, engineered for scale.
Modular 50–300 t/day plants with a three-stage grate furnace and HRDS flue gas treatment for sparsely populated regions in China and worldwide.
Core Technology
The three-stage mechanical grate furnace.
A modular reciprocating grate design that breaks the barrier to scaling down large grate furnaces, backed by 50+ patents.
Ultra-Low Emissions
HRDS: dioxin suppressed at the source.
A high-temperature flue gas system operating at 850–1100°C that removes SO2 and HCl and achieves ultra-low emissions.
22+ years of R&D
50+ patents across grate design, combustion and emission control.
Below national standards
Dioxin prevented at source; ultra-low emissions.

Why EcoTec
Technology that solves modular incineration.
Traditional modular incineration faces low efficiency, high pollution and costly operation. Qingfeng built a system around stability, efficiency and emissions.
01 / Combustion1
Three-stage grate furnace
A modular reciprocating grate that maintains stable combustion even with high-moisture, high-ash rural waste and mixed composition.
50–300 t/day
02 / Emissions2
HRDS flue gas treatment
Dioxin suppressed at source at 850–1100°C; SO2 and HCl removed with 30%+ lower consumables and fly ash.
Ultra-low emissions
03 / Recovery3
Zero discharge and resource recovery
Flue gas heat reuses leachate and wastewater; ash is screened and magnetically separated into recycled aggregates.
Zero wastewater discharge
