Abstract

Through source separation of biodegradable material, the Divided Waste Processing model, developed by the authors in Brazil, has the potential of diverting up to 85% of domestic waste away from landfills. Because a maximum diversion using traditional models of selective collection stands at 15%, the value put forward here introduces a new paradigm for consideration by municipal administrations. The success of divided processing of biodegradable and inert material depends on satisfactory source separation, which was demonstrated in residential sectors, condominium buildings, and grade schools. The destinations of biodegradable material were animal feed and compost; the composting operation was carried out in the neighborhoods of the test communities and can be accompanied by the residents. The inert material was disposed of by professional waste retailers. The long-term success of the source-separation procedure depends upon constant monitoring. In one of the test communities, the procedure continues to be operational after six years and diverts 67% of the community's waste from the landfill. The model is available for imitation in other test communities around the same city, until the extrapolation to larger sectors—through the application of appropriate managerial strategies—can be accomplished. Several possible strategies are discussed. Outside Brazil, the application will depend on local situations.
