Accounting for the Ecological Footprint of Materials in Consumer Goods at the Urban Scale

Abstract

The purpose of this article is to present the key elements for best performance and profitability of Municipal Solid Waste (MSW) management in a low-income city. The research provides an overview of methods and models for integrated planning of a two-phase program: MSW collection and transportation, and MSW treatment. We present the case study of Matadi (the Democratic Republic of Congo) that has a low level of the MSW management compared to other African cities. We develop a spreadsheet model for collection and transportation of MSW which is relevant for low-income cities and enables determining the waste collection fee. A CDM decay model is used to predict the GHG emissions in disposal site. The MSW treatment plant in case of Matadi is evaluated. For the anaerobic digestion technology selected as appropriate for this plant, the key factors that ensure profitability of the plant are as follows: tipping fee from the municipality (19% of total revenue), amount of carbon credits which can sum up to 16% of the total revenue, expansion of waste collection range from 25 to 50 km. The methods of this study can be used for solving waste problem in other low-income cities where the budget for municipal services is scanty, particularly when starting from a very low level of MSW management.

Open Burning of Household Solid Waste and Child Respiratory Health: Evidence From Indonesia

“…As for the exposure variables, almost half of the households reported burning their waste in the open (48.60%). This phenomenon is also found in major cities in other developing countries such as Brazil (Alfaia, Costa, &Campos, 2017), Sri Lanka (Karunarathne, 2015), the Democratic Republic of Congo (Din, G.Y., & Cohen, 2016), Ghana (Oduro-Appiah et al, 2017), Lao PDR (Babel & Vilaysouk, 2016),and India (Ramaswami, Baidwan, & Nagpure, 2016). This practice of burning waste is done usually to avoid rubbish from accumulating in residential area.…”

Analyse De La Viabilite Des Ong De Collecte Des Ordures Solides Menageres De La Commune De Parakou (Nord-Est Benin).

“…technico-organisationnels qui s'expriment par le manque d'équipements adéquats, le manque d'un système défini de collecte des ordures et l'inaccessibilité dans certaines zones (DIN et COHEN, 2013). En considérant la rapidité de l'occupation spatiale et la croissance de la population de la plupart des milieux urbains, avec une décroissance des taux de couverture et un accroissement des ordures produites puis une demande publique croissante pour l'amélioration des services (SALIFU, 2001); le besoin d'une méthode plus efficace de gestion des ordures devient urgent (OJO et al, 2015).…”
