Spray-on cooking oils seem pretty convenient, but they are expensive and create an awful lot of extra rubbish.

Let's say that even just one in 10 people in the US consume one can of cooking oil spray in a year - that's still 30 million cans that wind up in landfill. Sure, they can be recycled, but don't forget that recycling takes energy - heat to melt the cans - and other chemicals and environmentally unfriendly processes need to be used to reclaim the metal.

Next time you need cooking oil spray, consider buying a sturdy refillable pump spray pack and then also purchase light olive oil to fill it. Don't fill up the spray pack to the top, just enough to fulfil your needs for a month. This will save you money and is a greener alternative.
