The part of the rubbish dump that you see in this photo is for garden refuse like branches, leaves, grass, etc. The big yellow machine is used to chop larger branches into finer pieces that are easier to compress and dispose of.
Whenever I stop to drop things off at this rubbish dump there are invariably five or six guys around who are very keen to help people offload their unwanted goods. It's sad in a way, but as the saying goes, one man's trash is another man's treasure.
