A study published in Circular Economy reveals how integrated anaerobic digestion of agricultural waste in China’s Hengshui City has achieved a 64% reduction in greenhouse gas emissions while producing renewable energy and organic fertilizers. The research, led by Tsinghua University scientists and collaborators, underscores the transformative potential of circular economy models in aligning with the United Nations Sustainable Development Goals (SDGs), particularly SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action).
