Abstract(s)
The present case study was developed for the municipality of Porto, the second largest city of
Portugal that has near 300 000 inhabitants. Due to legislative evolution, some changes have been
implemented on MSW management practices since 1990 leading to meaningful improvements on
energy consumption and greenhouse gases emissions.
Two situations were compared: (i) the first one concerns the situation in 1990 where the MSW
produced was collected, a meaningful fraction of it was composted and the residual waste dumped;
and, (ii) the second situation where the EU legislation on recycling targets for packaging material
and diversion of organic waste from landfills was taken into account, including an incineration plant
on the management system. Greenhouse gas emissions from these two management scenarios were
calculated based on an inventory model developed by White et al (1992). Weighting factors for the
different gases based on the recommendations of the Intergovernmental Panel on Climate Change
were used to aggregate the emissions values and obtain a simple and comparable result for each
situation. Results show the advantage of the 2000 practices both in terms of energy consumption
and emissions of gases with greenhouse effect.
