With the project financed and underway, the comprehensive treatment of livestock and poultry manure pollution elements is already 15 percent completed.

"Zhuanghe is a major area for raising poultry and growing blueberries and strawberries. This subproject is a good example of tailoring solutions to local conditions," Li said.

The subproject uses poultry and livestock manure from Zhuanghe as the main raw material to produce organic fertilizer for local blueberry and strawberry plantations, he explained.

According to Li, the first-phase of the subproject can collect and treat 300,000 metric tons of livestock and poultry manure annually, along with 85,000 tons of agricultural straw waste.

It can also produce various types of fertilizers totaling 135,000 tons per year, including 30,000 tons of granular organic fertilizer and 30,000 tons of granular bio-organic fertilizer.

Li said that the bureau will accelerate the implementation of the EOD project in accordance with the requirements of the local government, aiming to establish it as a new benchmark for marine EOD projects in the province and even nationwide.

In recent years, the Liaoning Department of Ecology and Environment and the Dalian Bureau of Ecology and Environment have followed the national policy orientation and promoted the planning and application for EOD projects.

The Dalian bureau, together with the Dalian Development and Reform Commission and the Dalian branch of the China Development Bank, have issued a work plan to promote the EOD mode, organizing training and guidance.

According to Zhou Qiang, director of the science and finance department of the Dalian bureau, the EOD project for the ecological restoration and integrated development of an abandoned limestone mine in the city was entered into the national EOD project database last year.

He said that such projects should focus on problem-solving, emphasizing that bigger investments are not necessary, and that smaller, more refined approaches yield better results.

Zhou added that the original planned investment for the limestone mine project was 4.67 billion yuan, but that adjustments are being made to optimize and reduce the amount of investment needed.
