Counties, townships, and rural communities often face long waste collection and transport routes and limited local treatment capacity. Zhucheng Hongli Shengde Environmental Technology Co., Ltd. (HOLY SHIELD) provides complete municipal solid waste incineration systems and end-to-end solutions to address these challenges. Built around our proprietary 3T+E high-temperature pyrolysis and gasification technology, these solutions support waste volume reduction, resource recovery, and safe treatment in urban and rural areas.

1. Core Technology and Treatment Process

The 3T+E process coordinates four factors: temperature, residence time, turbulence, and excess air. The system thermally decomposes waste at 850–1,200°C under oxygen-free or oxygen-limited conditions, with a flue gas residence time of at least two seconds.

The quench system cools the hot flue gas to below 200°C within two seconds, rapidly passing through the temperature range in which dioxins can re-form. The gas then undergoes acid gas removal and baghouse filtration to meet the emission limits specified in China’s Standard for Pollution Control on Municipal Solid Waste Incineration (GB 18485-2014).

• Durable furnace lining. Mullite refractory castable helps extend the service life of the furnace.

• Negative-pressure operation. An intelligent sealing system helps maintain negative pressure inside the furnace.

• Reduced reliance on auxiliary fuel. Once the furnace reaches 850°C, it can continue operating without auxiliary fuel.

• Compact, modular design. Modular construction supports one-touch startup and shutdown and reduces the equipment footprint by approximately 50%.

• 

2. Equipment Range and Applications

• Rural communities, townships, and remote villages. On-site incineration systems for locally generated household waste.

• Counties and residential communities. Decentralized county-level systems and compact community units sized for daily treatment needs.

• High-altitude, mountainous, island, and cold-climate locations. Custom configurations adapted to local site and operating conditions.

• Scenic areas and tourism towns. Local waste treatment systems for visitor destinations and nearby communities.

• Existing waste treatment facilities. Retrofit and expansion equipment to improve operating efficiency and help facilities meet stricter emission requirements.

• 

3. Project Experience

HOLY SHIELD has implemented municipal solid waste incineration projects across China.

• Dulan County, Qinghai. The project, located at 4,099 meters above sea level, obtained a pollutant discharge permit and recorded a measured dioxin concentration of 0.035 ng TEQ/Nm³.

• Fuxin, Liaoning. All measured pollutant concentrations were below the applicable national emission limits.

• Other operating sites. Projects are in stable operation in Chamdo, Tibet, as well as in Inner Mongolia, Yunnan, Gansu, Sichuan, Yangshuo in Guangxi, and Fangshan District in Beijing.

HOLY SHIELD has also exported its equipment to South Korea, Myanmar, and other markets.
