We went out to complete last week, and while we were there for a few days, we saw a waste truck actually empty one of the bins. Basically you lift up the flap put your rubbish into the hole in the steel neck that sticks up out of the ground. Then when the truck comes long, it pulls the whole thing out of the ground. It is basically a big steel box that is pulled out of the ground, the truck then opens a trap door in the bottom of the box and all the rubbish then goes into the truck. The waste truck then returns the steel box back into its hole in the ground. Seems a very good system, and a good way to keep the place tidy. Peraleja have certainly not gone for the cheap option of placing lots of bins about the place, like every thing else, they seem to have done it correctly.
