The Suldouro landfill in Sermonde received the waste that has been produced since 1999 by the approximately 440,000 inhabitants of Santa Maria da Feira and Vila Nova de Gaia.
This landfill occupies 13 hectares and is 8 meters deep. During its period of action, that is, 17 years, it received approximately 450 thousand kilograms of undifferentiated waste per day, which is equivalent to 1.2 kg / inhab / day.
After its closure, this landfill will be transformed into a green park that can be appreciated by the population.
Landfills could get a longer lifespan if people separated the waste that could be recycled by depositing it into the Ecopoints. When this doesn’t happen, the residues are mixed in the undifferentiated waste and are dumped in a landfill. Since waste such as glass, plastic and packaging takes many years to decompose, they occupy space in the landfill, helping to fill it up more rapidly.
