This book was written with the aim of looking at how Municipal Solid Waste (MSW) is disposed of in the city of Pinheiro Machado, as well as showing the level of knowledge of the urban population in relation to MSW and its disposal, highlighting critical points of open-air waste and suggesting sustainable alternatives for the Municipal Government, schools and society as a whole, for example, carrying out campaigns in favour of protecting the environment and their own health. The general objective is to identify how MSW generated in the city of Pinheiro Machado is disposed of, as well as to assess the effectiveness of environmental education campaigns related to waste disposal in public places. In order to fulfil the general objective, the following specific objectives were defined: to identify the critical points of irregular waste disposal; to understand the risks of poor waste disposal; to identify possible waste collection points, whether or not they exist, and how many there are; to propose sustainable alternatives for public authorities, schools and society, such as the implementation of environmental education campaigns with the distribution of environmental education information material.
