Share tools and gadgets that people use infrequently rather than each of your neighbours buying their own individual items. Plan ahead and co-ordinate new purchases with your neighbours.
Use dried tea leaves as a deodoriser. Scatter them over the carpet, leave for ten minutes then vacuum up. Place in the fridge to absorb odours (like baking soda).
Filter water for all uses, not just drinking. Install a water filter instead of filling up those jugs.
Choose rechargeable batteries and a battery charger to cut down on disposables. Eventually recyclable batteries reach the end of their life too but they can be recycled – local recycling policies vary so check with your recycling facility.
Instead of buying paper napkins for each celebration buy cloth napkins that you can use again, or make your own.
If you only need a tool or piece of equipment infrequently then instead of buying one, save resources by asking a friend or neighbour if you can borrow one. Or check online for a lending club, such as Streetbank.
Take time to work out how much you need before making a purchase. If you do this for items such as food and paint you'll avoid paying for quantities that will only go to waste.
