Fig. 4: Geographic location of Jacareí [15]. Two order municipalities, São Silvestre de Jacarei and Parque Meia Lua, make part of Jacarei. The economy is based on three sectors of activities: agriculture (0.39%), industry, (51.74%), and services (47.87%). b) Landfill and useful life The landfill has an area of 792,550 m² located at a geographic coordinates N = 7,422,300 and E = 406,100. The landfill operation started in 2018 and it was projected to receive the household waste until 2040 but its useful life can be greatly increased with the recycling of waste. The MSW volume should be gradually reduced with the implementation of the environmental education plan, sorting unit, selective collection and the operation of the biodigestion plant. c) Population data The demand for urban cleaning services and MSW management services is calculated as a function of the population growth projection. The PMGIRS of Jacarei presents this projection with a 25-year horizon: it starts in 2015, the year of the forecast for the beginning of the actions foreseen in the PMGIRS and runs until 2040. The population growth of Jacarei accelerated with industrialization. The growing development of industries has led to boosted migration to the municipality, mainly in urban areas. Analyzing the data presented in the PMGIRS of Jacarei, it is possible to see that the urban population represents 98.62% while the rural population is 1.38%. Table 1 shows the estimated projection from 2020 to 2040 (expected year of landfill useful life) according to the PMGIRS of Jacareí. Table 1: Population projection of the Jacarei municipality [15].
