甘蔗糖业循环经济的实践模式、综合效益与深化路径研究OA

The development of a circular economy in the sugar industry represents a core pathway for achieving green transformation.This paper systematically analyzes the practical models,comprehensive benefits,and pathways for deepening such development.Three major practical models are summarized:the first is a closed-loop model centered on large-scale sugar enterprises,encompassing the entire industrial chain and enabling resourceful and high-value utilization of by-products;the second is an ecological circular model combining crop cultivation and livestock breeding,establishing a regional agricultural ecological coupling system;the third is a technology-driven biorefinery and energy expansion model.The overall benefits are assessed from economic,social,and ecological dimensions:turning by-products into profit sources,improving revenue performance,reducing production costs,and enhancing risk resilience;conserving resources such as wood and grain,and creating employment opportunities;and leveraging the strong carbon sink effects of sugarcane to achieve pollutant emission reductions across the full life cycle.Key challenges currently include insuffiicient capacity for technological integration and innovation,poor coordination across the industrial chain,high costs of green logistics,and the need for further improvements in relevant policies and market environments.Accordingly,this paper proposes systematic deepening pathways:strengthening technological innovation to break through bottlenecks in high-value utilization;innovating industrial organization models to build interest communities and specialized industrial parks;developing a green and intelligent supply chain to reduce costs and improve efficiency;and improving policies,standards,and market environments.These measures collectively support high-quality industrial development and the achievement of carbon peak and carbon neutrality goals.
