The compostadores do not currently include Vermiculture as part of their public operations, but for many without garden space, worms are the best solution. Worm castings are also a very high-nutrient addition to soil — the process is pretty magical.
LaVerme’s Worms is an organization based in Duluth that has been around since 1989. They do a great job answering all those worm questions you’ve ever wondered about (newspaper in bins, anyone? answer: no!). LaVerme’s also sells some useful resources and products if you’re interested in getting started.

Our friends at the Twin Cities-based Urban Compost also work to set up composting for high density units
