Can Vermicomposting Reduce Air Quality?

From Dee:

I vermicompost within a 500 square ft apartment and have been considering adding another bin. I often wonder if indoor vermicomposting has an impact on indoor air quality. After all it relies on decomposition and molds to break down food… I would be interested in hearing your thoughts on this… Thanks!


Hi Dee,

This is a very interesting question, and – like my responses to so many other questions relating to this quirky field of endeavor, I have to say…it depends!

Firstly, I will say that (in my humble opinion) a well-managed worm bin – or even multiple systems – shouldn’t create any air quality issues at all!

If anything, that sort of earthy-smelling decomposition would likely be good for you!

What I love about it – in comparison to most of the more typical weeds – is the abundance of lush foliage. A perfect “green manure” for any composting system – including one with worms!

I use comfrey a lot as a sort of “slow food” in my (more…)

Hello everyone,

Here is an update regarding the “Benefits of Castings & Leachate” experiment. And it has been a rough ride so far. At the start of the experiment it was still relative cold, with some freezing conditions in the night, and I decided to keep the experiment in a small cabin at the edge of a forest that borders my garden. A few days into the experiment the weather conditions changed a lot. We experienced (more…)
