Is this uniform across all of portugal? In spain, it differs by neighbourhood. Where I live, you drop landfill rubbish beside front door between 20:00 & 22:00 and it gets picked up. 100m away in another neighbourhood they have underground depots that you drop it into. In the newer parts of the city they do have containers on the corner of each block.

Since it's the responsability of the municipality it's impossible for me personally to tell, but I've been all over the country and the green (or grey, depending on location) containers are ubiquitous (or drop points with underground deposits, sure). If specific neighborhoods of Lisbon do it differently I'm afraid I wouldn't know. It's not impossible.
