Composting Tuesday: A Worm Bin is a Great Solution for Urbanites

Submitted by dpeacock on October 25, 2011

Commenter Maggie D weighed in yesterday, on Plastics Monday,  with the following comment, and we thought her conundrum deserved a proper blog post as a reply:   "My mom lives in the suburbs and I live in the city. We both hate plastic bags but find ourselves using them for garbage. Here in the City I have tried freezing stuff to take for composting but freezer space is limited & a worm bin scares me because I travel a lot. I can’t leave messy stuff around (mice & roaches would go crazy) and I’m required to bag garbage before putting it in the trash chute." -- Maggie D

Hi, Maggie!   As an urban-dweller myself here in Washington, DC, I had the same conundrum about composting, until I turned to a worm bin back in 2003, and drastically reduced my waste footprint by feeding my worms all of my organic scraps.  Worm bins are really doable, they're not smelly or messy if you maintain them properly, and depending on your travel schedule, your concern about being away a lot could actually be a plus:  the travel time might give the worms a "rest," if you've been producing too much waste for the worms to handle.

My experience has been that it's actually a delight to get to know your worms and form a symbiotic relationship with them, as your own household waste recyclers.  I use the worms' compost in window-sill herb pots, so the circle is complete, right there within my own urban apartment.  It's not quite the same as having a yard and getting to dig in the dirt, but that's what community gardens are for, so the worms do make a fairly acceptable garden-substitute for the urban apartment dweller.

The only times I've ever had a "problem," with the worm bin is if I have overfed the worms.  If you provide them more food than they can consume within a reasonable time, then it's true that the food could rot or grow mold in your bin, and then you have an ecosystem problem.  The rule of thumb for the ecosystem you're creating is to follow a two-to-one ratio, i.e. two pounds of worms can consume about a pound of food per day.  I follow this schedule by saving compost in the fridge or freezer, if I need to spread out how much food I'm giving them, and in eight years of tending my bin, I've only allowed a mold problem to happen twice.   You can do this; good luck!

The following articles on the Green America site  delve into composting in greater depth, if you need more info:

Also, on Maggie's original conundrum -- the plastic garbage bags -- I have to admit that while my worms drastically reduced my reliance on plastic garbage bags, I do still use them.  If you have a solution or suggestion for how to take the next step to reduce plastic in the trash-removal arena, please weigh in via the comments.
