Strategies for cost reduction in household municipal solid waste collection: a multiple study case As the world population increases , there is growing need in expanding municipal solid waste services in developing countries. There’s a lack of financial resources to bear the costs of waste handling. Therefore, there’s a need to develop waste collection cost reduction strategies. This work identifies strategies used by four municipalities in the state of Paraná, Brazil, to lower costs with household solid waste collection. It assesses the importance given to some strategies by the municipalities and identifies the parameters used to design and monitor waste collection services. A questionnaire about strategies and parameters established by Brazilian Association of Technical Standards and United Nations Human Settlements Programme was applied. Results indicate that the municipalities have different knowledge regarding strategies and collection parameters. The research indicates all municipalities know that there is a need to adapt to the better waste collection practices especially those regarding the use of public containers, performance monitoring, adequacy of collection frequency to waste generation, adequacy of collection vehicles to waste density and time of collection.
