China’s Burning Horizon: The Future of Hazardous Waste Incineration Technology

Introduction

China, grappling with massive amounts of hazardous waste, has embarked on a path of technological innovation to tackle this environmental challenge. Incineration technologies have emerged as a key solution for hazardous waste disposal, but traditional methods face limitations. To address these challenges, China is exploring advanced technologies to improve the efficiency, safety, and environmental impact of hazardous waste incineration.

Emerging Solutions

1. Fluidized bed combustion (FBC): Offers improved thermal efficiency and pollutant control through gasification.

2. Plasma arc incineration (PAI): Uses electrical energy to generate high-temperature plasma, enabling the complete oxidation of hazardous compounds.

3. Selective catalytic oxidation (SCO): Employs catalysts to enhance the combustion process and selectively oxidize hazardous substances.

4 vicissenergy conversion: Extracts energy from incineration flue gases to produce heat and electricity.

4 vicissenergy utilization: Utilizes waste heat to generate steam that drives turbines to produce electricity.
