Don’t Forget the Bulking Material

If you’ve ever wondered why your dry toilet sometimes smells, feels damp, or becomes difficult to empty. These are common signs that the balance inside the toilet container is off.

Every time you use a dry toilet, you’re adding something moist and rich in nitrogen — which can quickly lead to soggy, smelly, and compacted contents if left unchecked.

The solution is simple: use enough of the right bulking material.

It might seem like just a bag of dry stuff, but bulking material does a lot more than you think. It’s the magic ingredient that keeps your toilet clean, odor-free, and easy to maintain.

Why is bulking material so important?

Every time you use a dry toilet, you’re adding something wet and rich in nitrogen. Bulking material balances this by adding dry, carbon-rich matter. It absorbs excess moisture so the contents don’t become soggy, and it keeps the pile airy so that composting microbes can do their work.

On top of that, bulking material locks away odors, makes emptying easier, and speeds up composting. Without it, your toilet can quickly turn into a smelly, sticky mess — and nobody wants that.

How much should you use?

The rule of thumb is simple: add a scoop after every use. Just enough to cover what’s already there — about a generous handful. In winter or damp weather, a little extra helps keep things dry.

And don’t forget to sprinkle a base layer of bulking material in the bottom of the container before you start using your toilet. This way, it starts absorbing moisture from the first moment.

Which type of bulking material should you choose?

We offer two options, and both are designed to make your dry toilet experience as smooth as possible — you just need to pick the one that suits your toilet.

If you’re using a regular composting toilet that you scoop by hand, go for our Bulking Material for Compost & Dry Toilets. Its airy, coarse texture lets air circulate through the pile and keeps everything loose and easy to empty. It’s also great for your composters!

If your toilet has a built-in dispenser, the best choice is our Toilet Bulking Material, with its fine, smooth texture that flows easily through the mechanism without clogging.

Both of our bulking materials are 100% peat-free, which makes them a more sustainable choice for you and for the planet. By choosing peat-free products, you help protect valuable peatlands — which are important ecosystems and carbon sinks — and reduce your environmental impact.

A small habit with a big impact

Using bulking material is such a simple step — but it makes all the difference. You’ll enjoy a cleaner, fresher toilet, easier maintenance, and even contribute to the environment by turning waste into rich compost.

So whether you scoop by hand or use a dispenser, there’s a perfect bulking material waiting for you in our shop.
