Before buying anything ask, “do I really need it?”
The first ‘rule’ of being green is to use less. If you do need goods such as furniture could you get it second-hand or reconditioned?
Remember The 3 R’s of waste: Refuse, Reuse, Recycle!
Refuse to buy disposable rubbish in the first place. Only get things that can be reused and recycled, then make sure they are.
Try and complete the recycling loop; purchase recycled paper products, such as loo and kitchen rolls, office paper and envelopes. Most supermarkets and health food shops have these available, or they can be purchased online.
