Abstract(s)
The environmental burdens to air and water resulting from the MSW management
practices in the municipality of Porto were evaluated for 1990 and 2000 using the model
developed by White et al (White et al, 1995). The operations considered in the study are
collection, sorting, biological treatment, thermal treatment and landfilling. Savings from energy
and recycling of recovered materials are also quantified. For each pollutant, the main source,
among the operations considered, was identified. Results have shown that landfilling was the
main source for air and water emissions in 1990, followed by collection. In 2000, thermal
treatment was the main source for air pollutants and landfilling the main source of water
pollutants, in both cases followed by collection. In 1990, collection was the main source for air
emissions of particulates, CO, NOx, SOx to air, and of Organic compounds, Phenol and Fluoride
to water. In 2000 it was the main source of NOx to air and TOC, phenol, total metals and
fluoride to water. Biological treatment was the main source of N2O and nitrate to air in 1990 and
of BOD, COD and ammonia to water in 2000.
