The appropriate selection of treatment or final disposal for municipal solid waste generated by a population depends on multiple characteristics; decision-making becomes a challenge for those responsible for its integral management. Therefore, the objective of this research was to evaluate multi-scenarios of valorisation of the organic fraction of municipal solid waste. The methodology used included a sample of 421 houses to determine the generation and composition of the aforementioned municipal solid waste; this data served as input to be able to design four treatment and final disposal scenarios: current situation, composting, anaerobic digestion and landfill. The parameters of humidity, biochemical methane potential and biogas were used. In addition, organic fraction variability and treatment cost were considered. Data analysis included design of experiments with the uncertainty coefficient and predictive equations. The results showed that composting was the scenario that presented the highest coefficient of determination and therefore it would be the best choice to fit the particular conditions of the localities. It is concluded that this applied methodology can be used as a tool in the decision-making process regarding the valorisation of the organic fraction of municipal solid waste and can be replicated at a national and international level.
人口产生的城市固体废物的处理或最终处置的适当选择取决于多个特征;对于负责其整体管理的人来说,决策变得具有挑战性。因此,本研究的目的是评估城市固体废物有机部分的多种增值情景。所使用的方法包括对 421 户房屋进行抽样,以确定上述城市固体废物的产生和组成;这些数据可作为设计四个处理和最终处置方案的输入:现状、堆肥、厌氧消化和垃圾填埋。使用了湿度、生物甲烷潜力和沼气等参数。此外,还考虑了有机部分的可变性和处理成本。数据分析包括使用不确定系数和预测方程进行实验设计。结果表明,堆肥是呈现出最高决定系数的方案,因此它将是适应当地特殊条件的最佳选择。结论是,这种应用方法可作为城市固体废物有机部分增值决策过程中的工具,并可在国家和国际层面复制。
