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.
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.
Choose drought-resistant plants for the garden to cut down on the need for watering.
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.
Reduce toxins in the home – always leave outdoor shoes at the door.
Filter water for all uses, not just drinking. Install a water filter instead of filling up those jugs.
Sprinkle dry tea leaves to deodorise problem areas such as your cat litter tray.
