Facing with global sanitation and resources crisis, developing and identifying optimal sustainable sanitation system (SSS) is particularly challenging in most of global areas through conventional solution. A novel method by coupling macro-environmental content analysis, compatibility assessment, and multi-criteria decision analysis into structured decision-making is developed and applied to select the optimal SSS to improve the rural human settlements environment of Beijing, China. A predictive model of weighting coefficient has been proposed to deal with the interactions based on the data-driven method considering temporal (56-y time frame) and geographic (87 countries) factors. The technologies space with mature technologies of SSS came from 402 demonstration projects of the world. The results show that vacuum toilet + vacuum sewer + anaerobic digestion/composting (for blackwater) + struvite crystallization (for yellowwater), and biogas/composting toilet + gravity sewer + anaerobic digestion/composting is suitable for high and middle income Districts of Beijing, respectively, in the coming 5-10 years. Although the novel method is the first application in SSS planning, the proposed method can also be extended to apply to other complex infrastructure decision-making. |
