Abstract: Crop straws are utilized as fertilizer, animal feed, biofuels, industrial raw materials, and mushroom cultivation materials. Each method exhibits distinct technical features, and the difficulty in data acquisition makes it challenging for decision-makers to select the most sustainable technology. To comprehensively evaluate and prioritize straw utilization methods, an evaluation system consisting of 12 indicators of Technology-Economy-Society-Environment was constructed. The Life Cycle Sustainability Assessment (LCSA) method was used to evaluate these indicators. The Interval Decision Making Trial and Evaluation Laboratory (IDEMATEL) and the Interval VlseKriterijumska Optimizacija I Kompromisno Resenje (IVIKOR) were integrated to determine the weights of the indicators and to rank the technologies. The results show that the indicators with the highest interval weight values are net profit [0.119 0.263] and greenhouse gas emission reduction [0.097 0.219]. The comprehensive ranking result is fermented feed ≻ artificial board ≻ edible fungi ≻ direct combustion power generation ≻ crushed return to the field. The relative weights are 0.147, 0.173, 0.204, 0.236, and 0.241, respectively. Indirect returning methods such as manure, mushroom residue, and ash are more sustainable than direct returning. The results of the unidimensional ranking indicate that no single transformation pathway can maximize technical, economic, social, and environmental performance simultaneously. Sensitivity analysis further validates the robustness of the results, which can provide a reference for decision-makers to make appropriate choices based on needs and preferences.
