Everyday things, made to come back.

From the Bottle to the Home Kit, every Understory product is engineered from recycled materials and designed to be refilled, repaired, and eventually returned, so the things you reach for every day give back more than they take.

The greenest product is the one you already own. So we build ours to last a decade, refill them by post in plastic-free pods, and when they’re finally done, we bring them home and grow the next one from what’s left.

Every claim comes with proof.

We measure our footprint from seed to shelf to soil, and publish every number the day it’s audited. The good ones and the bad ones.

Ships, not planes.

Packaging.

Plastic-free fibre packs, moved by wind-assisted ocean freight. That cuts shipping carbon by 88% compared with air.

Run on sun and wind.

Energy.

Rooftop solar and community wind power our workshops, matched hour by hour, not just on paper.

Traced to the tree.

Sourcing.

Every fibre and metal is mapped by name to the forest, farm, or smelter it came from, then checked for biodiversity every year.

Every claim, footnoted.

Transparency.

Each number links to the meter reading, audit, or invoice behind it. If we can’t prove it, we don’t print it.

Rinse, filter, repeat.

Rinse water from our filling line is cleaned and reused three times, then returned to the river cleaner than we found it.

Ten years of free parts, tools and guides. The lowest-carbon product is always the one you already own.

We didn’t start a company. We started an argument with how things are made.

It began on a beach clean-up in 2019: four hundred bottles in one morning, every one designed to be thrown away. Seven years on, that argument is a supply chain that runs in a circle and plants a native tree for every loop it closes.

Design for the comeback.

Every product is planned around its return before it is planned around its launch.

Measure everything.

If we can’t meter it, we don’t claim it. Instruments over adjectives, every time.

Refuse the throwaway.

Repairable by default, refillable by design, and never quietly disposable.

Leave it wilder.

Every site we run must leave more living ground behind it each year than the last.

One system. Everyday essentials.

Five objects, one loop. Each is made from recovered material, built to last for years, and comes home to be remade when you’re done.

The Bottle. Our most returnable object yet.

One shell of recovered aluminium, a cap you can swap in seconds, and a free ride home when you’re done. Nothing about it ends in landfill.

How a bottle comes home.

A straight line ends in landfill. We built the journey as a loop.

01

We send it once.

Flat-packed in plastic-free fibre and moved by ocean, never by air.

02

You keep it for years.

Refill pods arrive by post or bike courier. Parts swap out. The bottle stays.

03

It comes back to us.

A prepaid label sends it home, where it’s melted down into the next one.

Done with it? We’re not.

Worn out, broken, or just unloved? Send it back. We repair what we can, recycle what we can’t, and send nothing to landfill. Free, every time.

The questions we get most.

Where do your numbers come from?

On-site meters, supplier invoices, and an independent audit every year. Each figure is published with its method, and nothing is ever rounded up.

Are you really climate positive?

Yes. Since 2023 we’ve removed more carbon than our whole supply chain emits, mostly through native forest restoration that we fund and monitor ourselves. The ledger shows the gap every year.

Do products actually come back?

Every order ships with a prepaid label. Returned units are repaired, refurbished, or broken down into materials for the next batch. Nothing goes to landfill.

How do the refills work?

Concentrated, plastic-free pods arrive by post or bike courier. Add water to the bottle you already own. A refill weighs 90% less to ship than a full bottle.

What does a return cost?

Nothing. Every order ships with a prepaid label, and pickups are free in every city we deliver to. If something arrives damaged, we replace it first and ask questions later.

Give back more than you take.

One honest letter a season: what we planted, what we fixed, and what we got wrong.
