Composting your leftovers is a great way to generate rich nutrients for your garden, but a real compost bin isn't a viable option for everyone. If you don't have the space or can't stomach the smell, creating cold compost in your blender is a great alternative.
Dave Manno at Dig It suggests throwing your food scraps in a blender as soon as you're done eating to make some instant compost. Just fill up the blender with plant scraps, coffee grounds, old newspaper and anything else compostable, then add water to just above the top of the scraps. Blend until you have a smooth purée, then spread it out in your garden, working the mixture into the soil with a trowel if necessary. A word of warning though; a $US20 margarita mixer probably won't cut it here. You'll want a powerful blender if you're attempting this with heavy scraps like banana peels.
The mixture isn't technically compost yet, so it might not see immediate benefits. However, breaking down the raw materials in a blender will let mother nature decompose them faster and your garden will reap the rewards without any additional work since the entire process is happening within the soil. Do this for a few weeks, and you should start noticing more earthworms and healthier plants, no smelly compost bin necessary.
