In an article published by China Environmental News, reporter Li Lifang and reporter Zhou shared insights from a pig farm in Yongnian County, Hebei Province, where innovative practices have turned waste into value. The Jianping Pig Farm has successfully transformed biogas slurry into animal feed, creating a sustainable model that not only reduces pollution but also brings significant economic returns—approximately 230,000 yuan annually per biogas system.
Farmers from across the country have visited this site to learn about its success. Guo Jianping, the farm’s director, emphasized how this project has proven that pollution control can be both environmentally responsible and economically beneficial. “I never thought a cost-effective pollution control project could also generate income,†he said. “Without government support and funding, this project wouldn’t have been possible.â€
During the 12th Five-Year Plan period, the Chinese government prioritized pollution control in large-scale livestock farming. In 2011, the Bengbu Municipal Government set deadlines for aquaculture enterprises to manage their waste. However, as environmental protection officer Jiang Shuli discovered during on-site inspections, many farmers lacked awareness, faced unstable markets, and struggled with limited financial support.
To address these challenges, Yongnian County implemented a multi-departmental approach. They organized meetings, created assessment methods, and assigned responsibilities down to the village level. By combining government leadership, departmental oversight, and enterprise participation, they enforced strict regulations and provided incentives for those who actively participated in pollution control.
The county also focused on setting examples. Enterprises that demonstrated positive results were given priority in receiving subsidies and environmental protection funds. In 2012 alone, over 3.8 million yuan was allocated for environmental protection projects, and more than 400 million yuan was distributed as subsidies for standardized livestock farming.
Through a combination of administrative enforcement and policy support, Yongnian County has developed a new model of ecological governance—one that emphasizes comprehensive utilization, pollution reduction, and a win-win situation for both the environment and the economy.
One key innovation is the use of biogas slurry as feed for pigs. This practice not only improves pig growth and reduces feed costs but also ensures zero discharge of wastewater. As Guo Jianping explained, using biogas slurry can increase daily weight gain by up to 0.7 kg and save over 80 kg of refined feed per pig. Additionally, the residue from biogas systems is used to fertilize vegetable greenhouses, producing high-quality organic vegetables.
Seeing the benefits, other farmers in the area have become eager to adopt similar methods. Recently, four aquaculture companies signed agreements with governance firms to implement similar projects. At the Jianping Pig Farm Demonstration Site, Zhang Shuangniu, a member of the Standing Committee of the Yongnian County Committee, highlighted the vision of turning all aquaculture enterprises into eco-friendly breeding households and integrating them with the vegetable industry to create a sustainable cycle.
This model demonstrates how smart policies, combined with practical innovations, can transform traditional farming into a greener, more profitable future.
