Create organic fertilizer inside or outside your home or apartment using nothing more than common household waste like newsprint, cardboard, and food waste. Composting worms eat the waste you place in the top and you collect the castings from the bottom.
This is the same "flow through" concept used in the world's top vermicomposting operations.
A combination of simplicity, breathability, and durability.

If you start from scratch, it should be about 4-6 months before you should expect to harvest worm castings from the bottom of your worm bag. You can reduce this time (and better ensure a happy home for your worms) if you start with an existing amount of vermicompost as a starter material.
This will depend on the ambient humidity wherever it is you keep your bin, whether or not you keep it indoors, and whether or not you keep it in your basement.
The Urban Worm Bag breathes so well that it can tend to dry out too quickly if left neglected.
In any case, if you grab a handful of vermicompost and squeeze it, you should be able to squeeze out a drop or two of moisture, much like a well-wrung out sponge.
If it's too wet, add some dry bedding and stop feeding for a few days.
If it's too dry, use a spray bottle or spritzer as needed to maintain appropriate moisture levels.
Your results are dependent upon too many variables to give you a good number.
However you can use commonly-known rules of thumb to get a very rough estimate. Conservatively, worms can eat 25-50% of their own weight per day and at maximum density, you will have around 2 lbs of worms per square foot.
The Urban Worm Bag has roughly 4 square feet of surface area. So an Urban Worm Bag stocked with 4lbs of worms will be able to process roughly 1-2 lbs of food waste per day under good conditions, roughly 50-70% of which will exit the worm in the form of worm castings.
A new edition of the definitive guide to vermicomposting--a process using redworms to recycle human food waste into nutrient-rich fertilizer for plants.
Author Mary Appelhof provides complete illustrated instructions on setting up and maintaining small-scale worm composting systems. Internationally recognized as an authority on vermicomposting, Appelhof worked with worms for over three decades before her death in 2005.
Topics include: bin types, worm species, reproduction, care and feeding of worms, harvesting, and how to make the finished product of potting soil.
Update: The Urban Worm Bag is now available on Amazon.ca! Once you buy it, send an e-mail to email@example.com and I’ll send you a MUCH better instruction manual than you will get with your purchase. I’m thrilled to announce that the Urban Worm Bag will soon be available on Amazon.ca! While Canadian customers are technically able […]
