Abstract：
This study tackles the growing global concern about municipal waste management, particularly in cities like the Grand Guayaquil Metropolitan Area (GGA). Through realistic field studies on in situ household waste generation and geographic information system (GIS) tools, this work offers a framework to predict the quantities and types of recyclable household waste for any metropolitan area in Latin America. Over 4 weeks, students collected, sorted and weighed recyclable waste types, including plastic, paper, metal, glass and fabric, from 776 sampled household of the GGA. ArcGIS survey tool identified household locations and allowed to survey different socio-demographic features. With the help of ArcGIS interpolation method, the total household waste generation for GGA was predicted, and the classification of the different types of recyclable waste was also spatially distributed for the study area. The report identified notable trends in plastic waste, specifically polyethylene terephthalate waste\'s steady prevalence and 42% growth rate, emphasizing the importance of enhanced recycling techniques. Spatial density maps showed a heterogeneous waste distribution across the GGA, emphasizing locations with higher waste output. This study demonstrates that improving recyclable waste collection can be accomplished with a moderately cheap expenditure by collaborating with academia to overcome knowledge gaps. This strategy provides opportunities to mitigate the environmental impacts of poor waste management.
摘要：
这项研究解决了全球对城市废物管理日益增长的担忧，特别是在大瓜亚基尔都市区（GGA）等城市。通过对就地生活垃圾产生和地理信息系统（GIS）工具的实际实地研究，这项工作提供了一个框架来预测拉丁美洲任何大都市地区可回收生活垃圾的数量和类型。超过4周,学生收集,分类和称重可回收废物类型，包括塑料,paper,金属,玻璃和织物，来自GGA的776个抽样家庭。ArcGIS调查工具确定了家庭位置，并允许调查不同的社会人口统计特征。借助ArcGIS插值法,预测了GGA的家庭垃圾总产生量，不同类型的可回收废物的分类也在空间上分布在研究区域。该报告指出了塑料废物的显着趋势，特别是聚对苯二甲酸乙二醇酯废物的稳定流行和42%的增长率，强调加强回收技术的重要性。空间密度图显示整个GGA的废物分布不均，强调废物输出较高的地点。这项研究表明，通过与学术界合作克服知识差距，可以以适度廉价的支出来改善可回收废物收集。这一战略为减轻废物管理不善对环境的影响提供了机会。
