Compo Charge: Break Down Waste Faster, Empty Less Often

Your composting toilet already works. Left to itself, the coir mix builds up its own community of beneficial microorganisms over time, and that community does the job of breaking down waste; that's the whole principle behind composting in the first place. Compo Charge™ doesn't change what happens. It changes how soon it starts happening, by adding a concentrated dose of the same beneficial microbes your mix would otherwise take time to build up on its own.

What Is Compo Charge?

Compo Charge™ is a naturally fermented, chemical-free blend of living microorganisms designed to kick-start and support the composting process in your toilet. It's ready to use straight from the bottle, non-GMO, non-pathogenic, and works with any composting toilet, not just Cuddy.

Why It Works Faster

Composting relies on a healthy, active population of microorganisms doing the breaking-down. A fresh coir mix starts with relatively few of them, and given time and the right conditions, it builds its own colony up naturally — nature takes its course, just on nature's timeline. Compo Charge shortcuts that ramp-up: instead of waiting for the mix to develop its own population from scratch, you're adding a big, ready-to-work dose of the same beneficial microbes straight away, so the process is doing more from day one rather than gradually getting there on its own.

It's the same underlying process either way — Compo Charge just means you're not waiting on it.

What This Can Mean for Travel and Emptying

Because the mix is doing more work sooner, a bin that's actively composting can handle more use before you need to deal with it — useful on longer off-grid stretches where getting to a dump point isn't always convenient. Compo Charge also helps control odours naturally by crowding out the bacteria that cause them, rather than masking smell with fragrance — a genuine difference in a small enclosed van or caravan bathroom, on top of whatever odour control your setup already has.

How to Use It

When	How much
Preparing a fresh coir peat mix	3 capfuls, added with the water used to prepare the mix
Ongoing, every 2 weeks	1 capful, to keep the beneficial microorganisms active

For a toilet used full-time — with the solids bin emptied and a fresh coir mix prepared every four weeks — one 500ml bottle lasts approximately one year.

Been sitting unused for a while? If your toilet's been in storage over winter, or just hasn't been used for a few weeks between trips, the microbial colony in the mix can wind down — especially if the coir has dried out. Rather than waiting for it to recover on its own, top it up with a bit of extra Compo Charge (and a little water if the mix is dry) to get things going again quickly.

Storage & Shelf Life

Store sealed and out of direct sunlight. Once opened, Compo Charge has an 18-month shelf life when stored correctly.

FAQs

Do I need Compo Charge for my composting toilet to work properly?

No — your composting toilet works on its own without it. Compo Charge simply adds a head start of beneficial microbes so the process gets going sooner, rather than waiting for your mix to build up its own colony naturally over time.

My toilet's been sitting unused for a while — what should I do?

If the toilet hasn't been used for a while, especially if the mix has dried out, add a top-up dose of Compo Charge to help re-activate the beneficial microbes and get the composting process going again, rather than waiting for it to recover naturally.

Does Compo Charge work with my composting toilet, even if it's not a Cuddy?

Yes — Compo Charge is suitable for any composting toilet, not just Cuddy.

How long does a bottle last?

With typical full-time use (solids bin emptied and fresh coir mix prepared every 4 weeks), one 500ml bottle lasts approximately 12 months.

Does it contain any chemicals?

No — Compo Charge is a naturally fermented blend of living microorganisms, with no chemicals or synthetics. It's non-GMO and non-pathogenic.

Will it get rid of odour completely?

Compo Charge helps control odours naturally by crowding out the bacteria that cause them — it works alongside good composting practice rather than replacing it, but it's a genuine, chemical-free way to help keep things fresher.
