Commissioning of Unit 1 of Shandong's largest waste incineration thermal power project
The No. 1 unit of the Zibo waste-to-energy project in Shandong Province, which has drawn significant public attention, has officially begun operations. Recently, Unit 2 entered its final commissioning phase, marking Zibo as the second city in Shandong to implement a waste incineration power generation project, following Heze. It is also currently the largest such project under construction in the province.
Huang Weipeng, Deputy General Manager of Zibo Environmental Energy Co., Ltd., explained that various types of waste, including vegetable peels and paper scraps, can be burned effectively. "Paper and plastic materials have high calorific value and low moisture content," he said. The waste is fed into the furnace in a 4:1 ratio with coal, allowing for efficient combustion. This process turns what would otherwise pollute the environment into electricity that is essential for daily life.
"Now we are in the trial operation phase. Unit 1 is running smoothly," Huang noted. "It processes 400 tons of garbage per day and generates 15,000 kWh per hour." Unit 1 has already started supplying power to the Zibo Power Grid. Compared to traditional coal-fired power generation, where 0.6 kg of coal is needed to produce one kWh of electricity, the waste incineration system only requires 0.2 kg of coal and 1.4 kg of garbage per kWh. This not only brings substantial economic benefits but also helps manage domestic waste efficiently, turning it into a valuable resource.
Concerns about pollution from waste-to-energy projects have been addressed. Huang emphasized that the project underwent rigorous environmental assessments before construction. "We maintain the burning temperature between 850°C and 950°C, ensuring complete combustion and reducing harmful emissions," he said. To further minimize pollution, the facility is equipped with a bag filter to capture dust. Additionally, wastewater from the process is sprayed into the furnace and burned, preventing any liquid waste from being released.
By the end of July, both boilers and units will operate simultaneously. Once fully completed, the project will handle 360,000 tons of waste annually, generate 160 million kWh of electricity, and supply 128 million kWh to the grid. This milestone represents a major step forward in sustainable waste management and clean energy production in Shandong.
