Evaluation of Green Logistics System of Solid Waste at Ports Based on Analytic Hierarchy Process

Abstract

This paper attempts to realize the green logistics of solid waste at ports, enabling the harmless treatment, reduction and recycling of such waste through the entire life cycle. For this purpose, the life cycle assessment and the analytic hierarchy process (AHP) were applied to evaluate the green logistics of solid waste at ports. Firstly, the solid waste logistics system was examined from the perspective of logistics system. Drawing on life cycle evaluation, the author analyzed how the solid waste logistics system affects the society, economy and environment. Meanwhile, an AHP-based evaluation system was established to quantify the overall impacts of solid waste. On this basis, the solid waste logistics system of a port was optimized, and subjected to life cycle assessment. The evaluation results show that the optimized system has much lower social, economic and environmental impacts than the original system. The research findings shed important new light on solid waste logistics at ports.

Does the Application of ICTs Improve the Efficiency of Agricultural Carbon Reduction? Evidence from Broadband Adoption in Rural China

“…Under the micro-scale efficiency driving mechanism, the development of land transfer market will increase land use to reduce agricultural yield losses [54]. Existing studies have shown that compared with small farmers, big farms with strong operational capacity, rich production experience and a high level of professionalism are more likely to accept and adopt low-carbon agricultural technologies [55]. As we know, land transfer promotes the large-scale management of cultivated land, and then changes the land use, thus regulating agricultural CO 2 emissions…”

“…Through the robustness and endogeneity analyses above, the relationship between rural broadband adoption and agricultural carbon emission reduction efficiency has been verified. However, existing studies have shown that compared with small farmers, land transfer operators are more likely to accept and adopt low-carbon agricultural technologies [55]. Information technology allows agricultural facilities to better realize the precision management of farmland to achieve carbon emissions reduction.…”

Land Circulation, Scale Operation, and Agricultural Carbon Reduction Efficiency: Evidence from China

“…Existing studies have shown that, compared with general farmers, the operators of transfer-in lands boast a strong operating capability, rich production experience, and high professional level. ey are more likely to accept and adopt low-carbon agricultural technology [32][33][34].…”
