The efficient utilization of agricultural waste resources lies in a modern and sound agricultural waste supply chain system for crops, but due to the problems of low density and strong seasonality of agricultural waste, the collection, storage, and transportation of agricultural waste are difficult, which in turn affects the utilization of agricultural waste for power generation. Therefore, a systematic analysis of the energy input and output of the agricultural waste collection, storage, and transportation system is needed. Through the theory of energy value analysis, combined with qualitative and quantitative comparative analysis methods and mathematical modeling, the resource utilization situation, environmental impact degree, and sustainability of the agricultural waste collection, storage, and transportation system are analyzed and compared from the perspective of two different agricultural waste collection and storage modes of agricultural waste collection and storage companies. The results show that the agricultural waste collection and storage system has a high degree of internal resource and environmental development, a high productivity, and a lower proportion of purchased renewable energy input compared to the manual and dispersed agricultural waste collection and storage model. The sustainable development capacity of the mechanical centralized model is obviously higher than that of the manual and dispersed agricultural waste collection and storage model.

摘要

The efficient utilization of agricultural waste resources lies in a modern and sound agricultural waste supply chain system for crops, but due to the problems of low density and strong seasonality of agricultural waste, the collection, storage, and transportation of agricultural waste are difficult, which in turn affects the utilization of agricultural waste for power generation. Therefore, a systematic analysis of the energy input and output of the agricultural waste collection, storage, and transportation system is needed. Through the theory of energy value analysis, combined with qualitative and quantitative comparative analysis methods and mathematical modeling, the resource utilization situation, environmental impact degree, and sustainability of the agricultural waste collection, storage, and transportation system are analyzed and compared from the perspective of two different agricultural waste collection and storage modes of agricultural waste collection and storage companies. The results show that the agricultural waste collection and storage system has a high degree of internal resource and environmental development, a high productivity, and a lower proportion of purchased renewable energy input compared to the manual and dispersed agricultural waste collection and storage model. The sustainable development capacity of the mechanical centralized model is obviously higher than that of the manual and dispersed agricultural waste collection and storage model.
