This work presents a mathematical model to estimate the solid waste generation in urban areas. The model was developed based on spatial physic basis of neighborhoods of Belo Horizonte and of the respective economic indicators of their population. A strong relation between per capita solid waste generation and per capita income was confirmed due the high coefficient of the determination 0.85. Afterwards the model was validated by means of Belo Horizonte and Porto Alegre datasets in which the estimated values were compared with the real solid waste generation provided by the local services. Despite of data set from Belo Horizonte, the results open the perspective of the application of the model for estimating the solid waste generation in urban areas.
