Abstract
Even though when the COVID-19 pandemic started, in 2020, the urban cleaning and solid waste management services were not disrupted in Goiânia, Brazil, they were directly affected by social distancing measures. Therefore, the goal of this study was to determine the environmental impacts of municipal solid waste management in the municipality of Goiânia, through life cycle assessment. For this purpose, quantitative data was requested to Companhia de Urbanização de Goiânia regarding waste collection (commingled and source-separated) and final disposal in the unlicensed landfill of Goiânia, between 2016 and 2020. To quantify the environmental impacts, six different scenarios were assessed with EASETECH, a specific life cycle assessment tool for waste, using 12 impact categories. Comparing the data of 2020 with 2019, commingled collection increased 2.2%, while source-separated collection decreased 7.6% than in 2019, mainly due to the changes in eating habits and lifestyle imposed by the pandemic. Concerning environmental impacts, the results indicated that scenario 2, which has the lowest of potentially recyclable waste diversions and relies on an unlicensed landfill, has presented the worst environmental result. Conversely, only by replacing the unlicensed landfill with a licensed one, reduces the environmental impacts between 68.5% and 75%. And when the amount of recycling was gradually increased in Scenario 6, the reduction in environmental impacts exceeded 84%.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
