This paper presents the results of the evaluation of urban solid waste in Jaú (SP) by means of samplings accomplished in 2001 and 2010. There were determined the quantity per capita, the specific weight and the gravimetric composition of waste generated in the neighborhoods Jardim América and Ameriquinha in 2010, comparing the results with a sample taken in 2001 with the same methodology. It was found that waste generation increased by 34.9% while the population grew 29.6%, leading to an increase of 4.0% per capita in generation of waste, which increased from 618 g. inhab-1.day-1 to 643 g. inhab-1.day-1. Waste generated in the county about is 50% organic matter, 25% wasting and 25% recyclable materials, percentages that have changed little in two samples. However, the soft plastic, among the recyclable material, was the one that had the largest increase (59%) in the evaluation.
