One of my neighbours is having their house renovated and workmen have been spending the morning throwing out rubbish and unwanted household items into a skip which was delivered this morning. When they'd gone for lunch some guy, who looked about 30, came cycling up to the skip and started rummaging through it. He took out two old computer monitors and other electrical items and, over the next hour, started taking them to bits and putting various components into his bag. He had plenty of tools with him so was fully equiped in advance for the job; pliers, hammer, screwdrivers etc. Having gathered everything he wanted he cycled off - with difficulty because the bag seemed very heavy.
Baffles me how scavengers like this suddenly appear out of nowhere. I can only assume he constantly cycles around in the hope of finding stuff in skips.
