Save electricity by running your washing machine on a cooler setting and consider line-drying your clothes instead of using a dryer.
Switch to LED lights. They cost less to run and last longer than any other bulb.
Grow houseplants for clean air and give them rainwater occasionally as it has less impurities than tapwater.
Rub beeswax over pans and baking sheets rather than use butter or oil each time. Over time the pan develops a permanent coating.
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.
Look at the types of products you use and switch from disposable to reusable, such as food and drink containers, razors and nappies.
Use charcoal deodorisers around the home to absorb rather than mask odours and toxins.
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.
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.
In the garden, use coffee grounds as a mulch for acid-loving plants or around the base of plants to deter ants and slugs.
Instead of buying paper napkins for each celebration buy cloth napkins that you can use again, or make your own.
To avoid creating waste, choose products with the least amount of packaging.
