Sprinkle dry tea leaves to deodorise problem areas such as your cat litter tray.
Replace at least part of your lawn with a meadow as a wildlife habitat, and cut down on the need for watering.
Save electricity by running your washing machine on a cooler setting and consider line-drying your clothes instead of using a dryer.
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.
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).
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.
Use beeswax candles instead of ordinary paraffin candles. They burn cleaner, brighter and last longer. They also emit negative ions which improve air quality.
Rub beeswax over pans and baking sheets rather than use butter or oil each time. Over time the pan develops a permanent coating.
Switch to LED lights. They cost less to run and last longer than any other bulb.
Instead of buying paper napkins for each celebration buy cloth napkins that you can use again, or make your own.
