My dad owns a recylcing business so we're pretty much raised on having green practices. The entire neighbourhood knows about it and they gladly come and dump their plastic at our home where we have a machine that compresses it for us before we ship it off! Strangely enough people love it doing it for no reward at all.
While in other communities we have a few people who collect plastic themselves in the neighbourhood and we pay people for collecting it so they generate a little income and keep themselves busy during the day. Its mostly old ladies though they love it
