Abstract

The generation of solid waste is a natural consequence of human life. Its rate has increase rapidly along the years, mostly due to the population growth, urbanization process coupled to industrialization and economic development. The uncontrolled disposal of solid waste in unsuitable sites, dump sites, has poses a threat to public health and the environment. In this regard Global efforts has been made to rethink municipal solid waste management toward sustainability. Middle- and low-income countries, such as Brazil, should seize the opportunity and centre efforts in the development and strengthen of an inclusive municipal solid waste management, supported by an innovative public policy where all government levels are integrated and focused on resource recovery and recycling through the organization and strengthening of waste pickers, in order to act directly in the income improvement of a marginalized portion of society as a result of the revenue generated by recovered and recycled materials sales, as well as reduce the CO2eq emissions consequent from the disposal of solid waste, among others, hence moving these countries towards the achievement of the SDG goals. In this regard, a well managed inclusive municipal solid waste system requires a reliable data source to support decision makers in the design of public policies with effective actions in the field, otherwise innovative and modern public policies will be filled with fruitless actions, thus, wasting the aptitude of the municipal solid waste management system in help middle- and low-income countries to successfully carry out the SDGs goals. Nevertheless, the estimation methods are a valuable tool for decision makers in middle- and low income countries to outrun the lack of solid waste information and doing so, increase the effectiveness of public polices towards a sustainable and inclusive municipal solid waste system, focused on mitigate negative impacts in the environmental sphere and potentiate the positive outcomes in the public health and human development sphere in these countries. This research proposed an estimate method based on the nominal income which is able to provide a reliable estimate of the residential solid waste generation, as well as its spatial distribution in the municipal level and within the municipal boundaries. The proposed approach has the ability to differentiate spatial distribution of the residential solid waste generation, weighting not just the number of people living in a determined space, but also the purchase power of those people, providing a more accurate view of the issue, which benefits decision makers to design and plan their polices and actions.
