Using Worms in a Compost Toilet

This is a brilliant, earth-friendly way to deal with waste and turn it into something that’s actually useful for your garden. Properly done, it’s clean, safe and a great example of a circular system.

Once your compost loo has done its job and you're transferring the waste into a dedicated bin, you can absolutely bring in the worms – just with a little patience and the right setup.

🐛 Which worms? We recommend a mix of Dendrobaena veneta and Eisenia andrei – aka composting worms who thrive in the top layers of rich organic matter. They’ll happily get to work on your matured loo waste, breaking it down even further into fabulous, crumbly compost.

🪱 When to add them? Wait until the waste has had a good 6 plus months to settle and mature. That gives it time to cool down, lose any acidity, and become worm-friendly. Too fresh and it’s just a bit too wild for even the hungriest wrigglers.

🧺 Which bin? We’d recommend the Green Johanna. It’s brilliantly insulated, rodent-resistant, and designed to deal with food waste and compost loo contents alike. It keeps the temperature up (great for breaking things down faster), has good airflow, and you can keep it going year-round.

🥕 What about kitchen waste? Absolutely. Once things are ticking along nicely, your veggie peelings, shredded paper, and even Bokashi-treated waste can go in. It’ll keep the worms well fed and the compost cooking along beautifully.

✨ Wiggly Tip: Set up a second bin if you can. That way, one can rest and mature while the other is being filled. And always cover fresh waste with carbon-rich materials like sawdust, straw or cardboard to keep things balanced and sweet-smelling.
