Spatial Distribution and Assessment of Biomass Energy Potential and Emission Reduction from Agricultural Waste in Zhengzhou
Year: 2026
Type: article
Abstract: This study, based on data from the 2024 Zhengzhou Statistical Yearbook, used the ARCGIS spatial analysis methods to evaluate the biomass energy utilization potential and emission reduction benefits of major crop straws and livestock manure in Zhengzhou. The results showed that the total biomass energy utilization potential of agricultural waste in Zhengzhou in 2024 was approximately 3.58×10⁵ t of standard coal, with crop straw accounting for about 3.07×10⁵ t and livestock manure for about 0.51×10⁵ t. Using crop straw and livestock manure as fuel, compared to standard coal, could reduce SO₂ and NOₓ emissions by 4.52×10² t and CO₂ emissions by approximately 1.99×10⁷ t. Specifically, the utilization of crop straw can reduce SO₂ and NOₓ emissions by 2.69×10² t and CO₂ emissions by approximately 8.17×10⁵ t, while the utilization of livestock manure can reduce SO₂ and NOₓ emissions by 1.83×10² tons and CO₂ emissions by approximately 1.91×10⁷ t. Through spatial analysis, the study revealed the spatial distribution characteristics of the biomass energy utilization potential and emission reduction benefits of agricultural waste, showing that agricultural waste resources in Zhengzhou were concentrated in major crop production areas and large-scale livestock farming zones, with high-value areas mainly concentrated in the eastern and southwestern regions. This study provided a quantitative analytical foundation for optimizing Zhengzhou’s agricultural waste resource utilization and biomass energy development strategies, and offered scientific support for promoting local green energy development and achieving the “dual carbon” goals.
