Why Should You Vermicompost?
Vermicomposting at home, school, or office is the purest form of recycling, full-stop.
Food waste is by far the heaviest form of household waste, meaning it is the most costly in terms of carbon cost to truck it away.
And unlike recycling paper, plastic, or glass, you can do it at home.
Why Use a Continuous Flow Worm Bin?
A continuous flow worm bin like the Urban Worm Bag leverages the worms' tendency to remain in the upper few inches of their habitat.
In most DIY bins, this means disturbing the worms in order to tediously separate the worms from the worm castings.
The Urban Worm Bag's bottom opening allows for easy castings harvesting without disturbing the worm workers above.
Why Choose the Urban Worm Bag?
Because of innovative design and ridiculous customer service.
I am always striving to find ways to improve the vermicomposting process for beginners and the Urban Worm Bag does just that by making the harvesting process a breeze.
And I'm proud of the fact that the Urban Worm Company has a reputation for over-the-top customer service. Problem with your UWB? I'll send you a new one or come up with a solution that keeps you happy.

Urban Worm Interview: Dan Lonowski of Michigan SoilWorks
About a year ago, I watched a fascinating time lapse video of the assembly of one of the most attractive continuous flow vermicomposting systems I have ever seen. Some guy named Dan Lonowski of Michigan SoilWorks and Gavin Newton of Detroit-area worm castings producer...
Vermicomposting 101: The #1 Cause of Worm Bin Problems
It seems to happen again and again and again. Armed with a bin, some bedding, and a shiny new arsenal of composting worms, eager new vermicomposters, our fellow foot soldiers in the War on Waste try to win the war literally overnight. And they often fail miserably....
Vermicomposting 101: Plant and Soil Benefits of Vermicompost
Some of us start vermicomposting to divert our household or farm waste away from the waste stream, and that is a benefit by itself. But what about the end product? If you're reading this, you're probably already aware that vermicompost, which includes the worm...
Urban Worm Interview Series: Soil Biology 101, Part II
In Part I of this interview about soil biology with Heather Rinaldi and Nina Folch, we learned some pretty crucial stuff about what constitutes excellent soil, how to recognize when it's good, and what to do about it when it's not. But the one thing we didn't even...
Urban Worm Interview Series: Soil Biology 101, Part I
I kind of always thought of soil as just "dirt", the stuff under the grass, the brown substance plants just magically grow out of. And it wasn’t until embarrassingly recently that I learned of the level of complexity that ecosystem that exists, or at least should...
A Really Cheap Way to Start a Worm Bin
A few weeks back, I asked my e-mail list that I affectionately (and maybe indulgently?) call "Urban Worm Nation" how they're all doing their vermicomposting. I am constantly amazed at how people used old refrigerators, discarded industrial equipment, and good old...
Harvesting Worm Castings: Break Your Back or Break The Bank?
I got the following question from Dawn F, a fellow worm composter from New York City. She writes: "Can you spend some time on how to harvest worm castings? I bought a small trommel screen and I gotta tell ya, it took half a day. Even the Worm Inn requires sifting."...
Worm Towers: Right Idea, But the Wrong Product?
Worm towers or worm tubes are an intriguing idea for turning food waste to worm castings. Unlike worm composting, which requires the worms, bedding, and food to be placed in some enclosure only to require you to harvest the castings, the worm tower is a...
Is the NCSU Vermiculture Conference Doomed?
If you've read this blog long enough, most of you know that I don't claim to have Jedi-level knowledge of vermiculture, vermicompost, or soil biology (or how to please women or dance in ways that don't make other people really uncomfortable). So it's with great honor...
