Use beeswax candles instead of ordinary paraffin candles. They burn cleaner, brighter and last longer. They also emit negative ions which improve air quality.
Grow houseplants for clean air and give them rainwater occasionally as it has less impurities than tapwater.
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 holidays closer to home and avoid air travel if you can to reduce your carbon footprint.
Instead of buying paper napkins for each celebration buy cloth napkins that you can use again, or make your own.
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.
In the garden, use coffee grounds as a mulch for acid-loving plants or around the base of plants to deter ants and slugs.
If possible replace disposable products with reusable ones (eg. food storage, coffee filters, straws, etc.).
Avoid creating waste. When ordering food avoid plastic utensils or straws by asking in advance.
Save and re-use the little sundries that come along with packaging, such as rubber bands, twist ties and boxes.
Those little fruit and veg labels that supermarkets use can be recycled too. Peel them off and stick them onto a plastic container in the recycling bin.
