BioFiltro – Vermicomposting Filtration Systems

I was recently digging through past posts on the RWC Facebook page (trying to find something I had remembered posting, and wanted to review) when I stumbled across another really interesting posting from a few years ago. It was a link for an article on “The Guardian” website entitled: California winery hires earthworms to clean up its wastewater, and I’m sure it must be the most “liked” and “shared” posting on the RWC FB page.

I can definitely see why!

The article describes the advanced bio-filtration process adopted by Fetzer Winery in California to handle their wastewater – one that relies on the use of a gigantic vermicomposting bed. According to the author, 14 gallons of water are used to produce a single glass of wine (most of it used for cleaning purposes)! The usual way of dealing with all this nutrient-rich effluent is to (more…)

5 Great Reasons to Use Vermicomposting Trenches & Pits

Unless you’ve been living under a rock, or are fairly new to the Red Worm Composting website, you’ll likely know that I’m more than a little passionate about the topic of vermicomposting trenches.

This is an approach that has truly had a massive impact on my vermicomposting journey, and even my life as a whole!

Earlier in the spring I had the honor of being able to share a (~ 50 minute) vermi-trench presentation at the Homegrown Food Summit, and was blown away by all the positive feedback. Clearly this is a topic of interest for a lot of people.

More recently, I (finally) released the early edition of my new course, Trench Vermicomposting – and I can’t tell you how excited I am about that as well.

So what exactly is the BIG deal about this type of vermicomposting system anyway?

Well, firstly – I want to make something very clear. I know (more…)

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 you consider the sort of decomposition processes that take place in say a forest, for example – there’s virtually no way that would ever be a hazard (unless you have some sort of allergy, which we will come back to in a minute). If anything, that sort of earthy-smelling decomposition would likely be good for you!

So what does “well-managed” mean?

In basic terms, you should have a system containing (more…)

Comfrey as Sole Food Source for Worms

If you’ve followed the blog for a number of years, you’ve likely seen some mentions of my favorite plant for vermicomposting – comfrey!

Not sure comfrey would be considered a weed – but it sure grows like one, sprouting up easily from even the tiniest little root fragment (funny irony is that it took me forever to get it established via seeds originally).

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…)
