I do when it's not much by way of extra effort. At home it's reasonably easy to set aside glass, tins, card and paper to go in a separate bin to normal household waste. It's lucky then that all recyclables can go into one bin, and we don't have to separate them as that's more effort than I'm willing to expend. I don't care about the environment enough to put in much time.
At work, they only recycle paper. Years ago, we took delivery of 70 new PCs, complete with monitors, keyboards and mice. We also got 120 VCRs. All of the equipment was destined to go to various points around the school I work at. Each item came in a cardboard box, that even flattened, filled an entire classroom wall to wall.
I called up the local council about taking it for recycling and they said they didn't offer the service. The company I was employed by were a business and didn't want to spend any money so the whole lot got skipped. It is a little unsettling to know that all that cardboard ended up in a landfill somewhere.
