The National Solid Waste Policy (PNRS) by the Law 12,305 of Aug. 2nd in 2010, is the Brazilian initiative to manage the Municipal Solid Waste (MSW) generated in the national territory. The Metropolitan Region of São Paulo (MRSP) is the largest Brazilian economic macro-region which generates 10% of all MSW in the country which is practically 100% treated in landfills, as suggested by the PNRS. However, its landfills are close to the exhaustion and build new ones collide with the lack of land availability in the region surrounded by water reservoirs. Areas far from the waste generation do not seem to be an economical alternative, due to high freight fee and requirements for environmental licensing.

Solid Waste Treatment

Despite the National Policy for Solid Waste (PNRS) in 2010, nothing has changed to the waste disposal in Brazil. Planned to reach 100% of all Municipal Solid Waste (MSW) collected and treated in landfills by Aug. 2 nd, 2014, until nowadays, 42% of this total remains in dumps. Even the most important national economic region treating its urban waste in landfills, what it has is no more than 4% of recycling and its landfills reaching the exhaustion.

Accurate prediction of municipal solid waste (MSW) generation is necessary for choosing appropriate waste treatment methods and for planning the distribution of disposal facilities. In this study, a hybrid model was established to forecast MSW generation through the combination of the ridge regression and GM(1,N) models. The hybrid model is multivariate and involves total urban population, total retail sales of social consumer goods, per capita consumption expenditure of urban areas, tourism, and college graduation. Compared with the constituent models alone, the hybrid model yields higher accuracy, with a mean absolute percentage error (MAPE) of only 2.59%. Through weight allocation and optimal treatment of residuals, the hybrid model also balances the growth trends of the individual models, making the prediction curve smoother. The model coefficients and correlation analysis show that population, economics, and educational factors are influential for waste generation. MSW output in Hangzhou will gradually increase in the future, and is expected to reach 5.12 million tons in 2021. Results can help decision makers to develop the measures and policies of waste management in the future.
