Generation of Domestic Solid Waste in Rural Areas: Case Study of Remote Communities in the Brazilian Amazon
2014
Bernardes, Carolina | Risso, Wanda Maria de
The Brazilian rural population is estimated to be around 30 million people and many rural areas do not have universal access to basic infrastructure services, including those related to solid waste. There are very few scientific studies on rural domestic solid waste and more investigative work is needed to provide information for appropriate solid waste management policies. This paper aims to characterize rural domestic solid waste in terms of quantity and quality. Amazonian rural communities were chosen for our case study. The issue of domestic solid waste was characterized both by means of interviews, at household level, and by a study of industrialized products traded in the communities located along the banks of the Juruá River, in the Brazilian Amazon. Quantitative results have shown that generation of solid waste in these rural communities reaches 0.5 kg/person/day. Organic matter represents 90 % of domestic solid waste generation and is mainly reused to feed animals and/or is composted using a method called paú. Inorganic solid waste (10 %) is either reused, burned or inadequately dumped in open sites. Based on these data, the annual production of solid waste is 437 tons per year in these communities. Since infrastructure services are virtually non-existent in this rural context, even this amount of solid waste may have a serious environmental impact, with negative effects on the population’s health, particularly in terms of hazardous waste. Even though solid waste management solutions for rural populations might not always be based on economic efficiency, decision makers responsible for development and planning should present solutions that are socially, technologically, environmentally and economically suitable for this context.
