Incineration Goes High-Tech: New Developments in China’s Waste-to-Energy Landscape

Introduction

In China, waste management has become a pressing concern due to rapid urbanization and population growth. Incineration has traditionally been used as a waste-to-energy (WTE) technology, but in recent years, China has witnessed significant technological advancements in this field. These developments enhance the efficiency, sustainability, and environmental performance of incineration.

New Technological Advancements

1. Advanced thermal plasma technology: This process uses high-temperature plasma to break down organic waste into gases and condensed products. The resulting gases can be used to generate electricity or fuel.

2. Integrated energy generation systems: These systems combine incineration with technologies such as supercritical water or steam turbines to produce both heat and electricity.

3. Microincineration: This small-scale incineration system is suitable for treating hazardous waste and medical residues.

4 Künsten technology: This system recovers valuable metals from municipal solid waste through a multi-stage separation and electrolysis process.

Challenges and Opportunities

While high-tech incineration offers significant potential, challenges remain in terms of:

• Ensuring efficient capture of pollutants.
• Minimizing greenhouse gas emissions.
• Developing technologies for the safe and environmentally sound disposal of bottom ash.
