Avaliação do plano de gerenciamento de resíduos em usina termoelétrica na Ilha de Cotijuba no município de Belém-PA

Abstract

Electric energy is considered one of the greatest vectors of social development, associated with quality of life and health and has been the subject of several studies for its rational, integrated and sustainable use, and may have its origin in renewable and non-renewable sources of energy. energy. In Brazil, the most used source in energy generation is hydraulic, due to its favorable geographic conditions. However, it is known that this alternative generates major environmental and social impacts, in addition to not covering the entire territory of the country. In the Amazon, due to its organizational, economic and geographical form, many locations further away from the municipal headquarters are not part of the National Interconnected System (SIN), a transmission network that covers most of the Brazilian territory. As a result, isolated power generation systems are needed, where most are supplied predominantly by thermal sources, such as diesel oil. In the state of Pará, the activity of the company SoEnergy International stands out, which supplies six municipalities, including the municipality of Belém, on the island of Cotijuba. The generation of electricity through thermoelectric plants has a high need for energy resources and intensive environmental impacts, including atmospheric and liquid pollutants, and hazardous oily waste. The increase in the generation of waste to the environment, entails negative consequences that can become irreversible, so it is extremely important to develop control and monitoring plans to manage them. In view of this, the objective was to propose improvements in the Solid Waste Management Plan through the evaluation of the diagnosis of waste management from the operation of a fossil fuel thermoelectric plant, on the Island of Cotijuba-PA. The environmental diagnosis showed some inconsistencies and non-conformities related to waste management at the UTE and in its PGRS. In this way, improvements were suggested for the identified nonconformities and the suggested changes were monitored during the period from January to November 2021, as well as the annual volumetric quantification of hazardous solid and liquid waste.
