Efficiency hierarchy and optimization of waste incineration in China to balance disposal and energy supply
This study analyzes 2,151 waste-to-energy (WTE) incinerators across China, revealing their significant contribution to residential electricity (7% in 2023). A three-tier classification (disposal-oriented, energy-recovery, green energy) based on energy efficiency is established. Projections indicate WTE could generate up to 259 TWh by 2035 (13% of residential demand). Artificial intelligence-based control and waste heat recovery are identified as the most cost-effective optimization strategies, potentially mitigating up to 60% of greenhouse gas and flue-gas pollutant emissions. These findings offer crucial guidance for redefining WTE's role in global waste and energy transitions.

Influencing Factors on Energy Efficiency
The energy efficiency of WTE facilities is influenced by multiple factors, including MSW composition, combustion process, energy recovery systems, FGP control technologies, operational experience, and local climate. Higher LHV waste typically improves efficiency, but regional disparities and operational mismatches with design specifications can limit performance.

Three-Tier Efficiency Classification
A novel three-tier classification framework was established based on energy efficiency performance, categorizing WTE plants into disposal-oriented, energy-recovery, and green energy plants. This framework enables a more refined evaluation and benchmarking of facilities, aligning with international standards and China's Green Power Certification.
| Category | EEef-adjusted Threshold | Key Characteristics |
|---|---|---|
| Disposal-Oriented | < 0.65 |
|
| Energy-Recovery | 0.65 ≤ EEef-adjusted < 0.77 |

Cost-Effectiveness of Optimization Strategies
Introducing artificial intelligence (AI)-assisted control models to improve operational performance is identified as the most cost-effective strategy per additional unit of recovered energy. Internal thermal cycle optimizations and waste heat recovery measures (e.g., organic Rankine cycles, flue-gas condensation) rank second, maximizing energy recovery from low-temperature flue gas.
AI-Driven Operational Performance
Summary: AI-assisted control models offer the highest cost-effectiveness for enhancing WTE energy recovery. These models optimize combustion, predict maintenance needs, and manage energy output, leading to significant gains in efficiency with minimal incremental cost.
Learnings:
- AI integration significantly reduces operational costs and improves energy output.
- Predictive maintenance and real-time optimization are key benefits.
- Initial investment in AI yields substantial long-term returns in energy recovery.
