National Rural Renewable Energy Statistics Summary Table for: Department of Science, Technology and Education, Ministry of Agriculture. According to the analysis, further improving mechanization level in straw collection, storage, and transportation process, optimization of transportation tools and strategies, and equipment performance improvement could be a viable pathway to achieve the synergistic optimization of efficiency, cost, and carbon emissions. The pretreatment processing in straw transfer site is the determined factor to decline the carbon emissions, with the Scenario I and II accounting for an average of 59.2% of the total emissions. The transportation process would play an important role in cost reduction, wherein baled straws could lead to an average reduction in transportation costs of 66.1%. In contrast, Scenario II, III, and IV achieved reduction in collection costs by 34.4%, 54.1%, and 60.3%, respectively, while carbon emissions reducing by 25.3%, 55.2%, and 65.9%. ![]() ![]() The results indicate that, while achieving collection efficiency within 30 days, the scenario I exhibited the highest collection costs (460.9 CNY/ton) and carbon emissions (65.4 kg CO 2/ton). Four typical scenarios are selected to identify co-benefits in the town scaled straw transfer site: all-manual collection (I), 50% manual collection (II), small-scale machinery collection (III), and large-scale machinery collection (IV). The off-field utilization of crop straw requires a highly efficient collection, storage, and transportation system, focusing on the synergistic optimization of efficiency, cost, and carbon emissions.
