探索“无废农牧”新模式，云浮新兴让畜禽粪污“变废为宝”

Core Viewpoint - The article highlights the transformation of traditional livestock farming in Xinxing County, Guangdong Province, towards an eco-friendly and resource-recycling model, addressing pollution issues while promoting sustainable agricultural development [1]. Group 1: Transformation of Livestock Farming - Xinxing County has shifted from a "heavy farming, light governance" model to an intelligent, ecological, and resource-oriented approach, creating a "waste-free agricultural and animal husbandry" closed-loop system [1]. - The county has successfully implemented a "pig-biogas-field-fish" and "pig-biogas-forest" ecological agricultural cycle, turning waste into valuable resources [2][5]. Group 2: Resource Utilization and Economic Benefits - The high village pig farm processes waste into biogas, liquid fertilizer, and solid waste, achieving over 95% resource utilization of livestock waste [2]. - The farm's 105 acres of arable land can absorb 20 cubic meters of biogas liquid and 1 ton of pig manure per acre, resulting in a 60% utilization rate of biogas liquid and 100% for pig manure, significantly enhancing crop yield and quality [3]. Group 3: Technological Innovations - The county promotes a "company + base + farmer" model for intensive farming, leveraging IoT and big data for smart upgrades, which improves livestock growth efficiency and reduces waste generation [5]. - The introduction of solar oxygen machines and energy-efficient pumps, combined with smart control systems, optimizes energy use and reduces carbon emissions in livestock farming [7]. Group 4: Extension of Waste-Free Concept - The successful practices in the agricultural sector have led to the initiation of "waste-free county" and "waste-free agricultural town" projects, aiming to extend the waste-free concept to urban construction, industrial production, and daily consumption [8]. - The county is focused on creating a model that balances ecological and economic benefits, with ongoing improvements in the "waste-free agricultural" model expected to provide replicable experiences for other regions [8].
