it is from the environmental sense and plastic etc but not for £££. They are as cheap as chips which is why they are free and tbh it probably costs more to send back than it would be to give someone a new one so you wouldn't be saving them money. The best thing you can do if you want to do the right thing is take it to your local council/tip/dump/recycling centre and ensure the cardboard/electronics/plastic gets recycled properly. There is no point keeping it for a spare because by the time you need it (in a year or two) there will be a new shub out with new technology which you'll want and they will insist on giving you as part of their cpe upgrade programme.
