Improving urban waste management: A comprehensive study on household waste generation and spatial patterns in the Grand Guayaquil Metropolitan Area.

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.

Informal waste pickers in guayaquil: Recycling rates, environmental benefits, main barriers, and troubles.

Systems for managing municipal solid waste are typically ineffective in developing nations because of governments' deficient financial and administrative frameworks, poor rules, and a lack of suitable infrastructure and human resources. The informal sector plays an essential role in these systems by reprocessing waste into secondary raw materials, reducing collection and disposal costs, and, most importantly, benefiting the environment by avoiding incineration and landfilling. However, their actual contributions remain unknown.
