Panorama da coleta seletiva com catadores no município de Maputo, Moçambique: desafıos e perspectivas

Abstract

In Maputo, the selective waste collection is undertaken in a very limited way and is largely a result of nongovernmental projects or individual initiatives. The objective of the study was to analyze household selective waste collection in Maputo emphasizing those in partnership with the municipality, in order to evaluate their potentialities. The research methods were bibliographical and documental research and qualitative interviews. The interviews were with representatives from: Municipal Directorate of Cleansing and Cemeteries; coordinators of four pickers' organizations (Recicla, Fertiliza, Amor and Pagalata). In addition, there were technical visits to units for sorting recyclables and collecting/selling stations. The research showed that the initiatives are positive, in terms of social and economic capital, although altogether the projects deviate less than 1% of the urban solid waste produced daily in the municipality. One of the major problems for promoting selective waste collection in Mozambique is lack of local industries that transform recyclable materials in recycled products. It is therefore important to provide a legal framework for municipal selective waste collection service with pickers' and citizens' participation.

Application of material flow analysis to municipal solid waste in Maputo City, Mozambique

“…At the household level, much of the MSW is reused and recycled, especially as most of the households subsist on low incomes. Examples include food waste that is used to feed domestic animals, glass and plastic bottles that are reused within the household or otherwise quickly removed from the waste stream, and large items such as old furniture and electrical appliances, which are reused wherever possible even when barely functioning (Allen and Jossias, 2011; Buque, 2013; Maputo Municipal Council, 2007).…”

“…Other sources are hotels, restaurants, supermarkets, and public and private institutions. Waste generators and workers from processing companies also contribute to the collection and assembly of recyclables (Allen and Jossias, 2011; Associação Moçambicana de Reciclagem [AMOR], 2013; Association of Italian Lay Volunteers [LVIA] and Caritas, 2009; Buque, 2013; PagaLata, 2008).…”

“…The compost is produced from the organic waste of city wet markets and is sold to local purchasers, chiefly in the agricultural sector. Composting activities were interrupted for almost a year in 2012 but resumed in 2013 with the intent of recycling 600 tonnes of organic waste per year (Allen and Jossias, 2011; Buque, 2013; LVIA and Caritas, 2009). Table 4 summarizes the available data concerning the material recovery activities in Maputo City.…”

Análise do processo produtivo e capacidade operacional de uma organização de coleta seletiva de resíduos sólidos – estudo de caso asnov garanhuns

“…Entretanto, ainda que possuam grande relevância para um gerenciamento mais adequado de resíduos, a ausência nessas organizações de noções apuradas da capacidade de seu processo ou desempenho de seu sistema torna sua gestão, muitas vezes, desafiadora. Estudos presentes na literatura abordam frequentemente as organizações de catadores de resíduos sólidos em análises e propostas envolvendo as dimensões social, político-institucional e ambiental (AQUINO, CASTILHO JUNIOR, PIRES, 2009;GOMES et al, 2012;MARCONDES, 2012;ALENCAR, SANTOS, 2013;BUQUE, RIBEIRO, 2015;MARQUES, SANTOS, 2016), ocupando-se pouco da análise de sua dimensão produtiva.…”
