These plant-based kitchen sponges are a non-toxic, microplastic-free alternative to synthetic sponges. Durable, compostable, and made for everyday cleaning.
Why Microplastic-Free Matters
Most kitchen sponges are made with petroleum-based plastic foams and synthetic scrub layers. They scrub your plates, wipe your benches, sit in water, and wear down with every use.
These sponges are a plant-based, plastic-free alternative for the dishes, surfaces, and messes you clean every day.

Why plastic-free matters
What cleans your kitchen matters
Most kitchen sponges are still made with petroleum-based plastic foams and synthetic scrub layers.
They scrub, wipe, rinse, and wear down with every use - sitting in the sink where your dishes, glasses and cutlery are cleaned.
Our sponges are made from wood cellulose and coconut fibre instead - a plastic-free replacement for the one you use every day.
What We Use Instead
Why we chose wood cellulose & coconut fibres
Most sponges are made from synthetic plastic foam. Every wash, they shed - into your water, down your drain, onto your dishes.
Wood cellulose absorbs like nothing synthetic can. Coconut fibre cuts through grease without touching your non-stick coating.
Two materials. Nothing synthetic. Nothing left behind.
Built to last
Sponges that go the distance
Most synthetic sponges last a week before
they smell, fall apart, or end up in the bin.
Wood cellulose dries faster than foam -
which means less bacteria, less odour, and
a sponge that holds up through the whole pack.
No landfill guilt
Compostable when you're done
Most sponges end up in landfill as a lump
of plastic foam that will outlast everyone
in your household.
These don't. The cellulose composts in your home bin. The coconut fibre breaks down naturally.
Throw them away guilt-free.

FAQs
Will these actually scrub properly?
Yes. The coconut fibre side is tougher than it looks - it cuts through grease and stuck food without needing to scratch the surface to do it.
How long does each sponge last?
Your sponges will typically outlast synthetic foam alternatives.
Wood cellulose dries faster between uses which means less bacteria buildup and less degradation over time.
How long depends on how hard you use it, but you won't be replacing them weekly.
Will they smell like a normal sponge?
No. The smell from conventional sponges comes from moisture trapped in synthetic foam.
Wood cellulose dries out properly between uses. Less moisture means less bacteria, which means no smell.
Are they safe around food?
Yes. No synthetic materials, no plastic foam, no chemical binders touching your dishes.
Wood cellulose and coconut fibre are both food-safe materials used in kitchens specifically because they don't leach anything into what they touch.
How do I clean them?
Rinse under warm water after each use and wring out fully.
The key is letting them dry out completely between uses - that's what keeps them fresh and extends their life.
What size are the sponges?
Each sponge measures 11 cm x 7 cm x 2 cm (4.3 in x 2.8 in x 0.8 in).
