There’s a great deal of energy and processing that goes into the manufacturing of aerosol-based sprays. The can itself is made from steel, often with plastics for the nozzle and cap. Some of the chemicals and propellants in aerosols can be pretty nasty too, if not directly, then often their by-products are.

Using pot pourri, you can recycle tree and plant matter by refreshing with new fragrances when the scents wear off. You can also use eco-friendly oils and organically grown flowers. You can save quite a lot of landfill waste by avoiding aerosols!
