Just because you don't have a backyard doesn't mean you can't compost. All it takes is a little creativity, a few free hours and some power tools to make a portable bin

There are under-the-sink compost bins like the ones from Apartment Therapy and diyNatural.

There are homemade vermicomposting bins full of red wiggler worms made by Tim Musson and Leigh Bush.

And for folks who want to combine their composting with their growing, Garden Tower Project offers a bin perfect for a balcony or front porch.
