Abstract: This article aimed to evaluate, using statistical tools, the generation and composition of municipal solid waste (MSW) in the city of Belém, Pará, from nine urban collection sectors in the municipality and the average nominal income of the population. Approximately 900 kg of urban solid waste was collected from the municipality in the period from 2021 to 2022. Statistical tests were carried out on hypotheses with 5% significance in comparative evaluations and their respective average nominal incomes. The results indicated that the organic fraction corresponded to 55.57% of the waste generated in the municipality, 14.26% was inert waste (potentially contaminating), and 0.67% was miscellaneous waste. It was observed that the waste generated by families with high purchasing power tended to contain higher percentages of recyclables while in families with lower purchasing power, the highest percentages tended to be organic. Knowledge of the generation of MSW is fundamental for the choice and dimensioning of operations and processes involved in the management chain at the municipal level. The decentralization of services offered based on solid waste management would enable greater success in serving the population.
