I love it when you find great new uses for what would otherwise be rubbish. My favourite example is Nutella jars. I love the chocolate spread but I only ever buy the small jars. Normally I'd go for the biggest jar so that less packaging is used per product but for me the Nutella is really a side product. It's the fantastic jars you're left with once you've finished that I want. Take off the lid and wash away the paper and you're left with a perfect juice jar. And we all know reusing is much better than recycling!
