Our leather is made mainly from apple waste recovered from the juicing industry (skin, flesh and seeds). Third-party radiocarbon testing confirms 69% biobased carbon content, and it is USDA BioPreferred Certified. Its biobased portion is biodegradable (supplier data: about 300 days in soil); the material also contains about 31% PU base.

Our apple leather is certified under the U.S. Department of Agriculture (USDA) BioPreferred Program, with its biobased carbon content verified by a third-party lab (Beta Analytic) through ASTM D6866-22 radiocarbon testing.
The remaining 31% is a PU resin carrier, which provides strength, flexibility and water resistance. Paired with a spunlace natural-fibre backing, the material as a whole remains fully biodegradable.

The global juicing industry produces about 4 million tonnes of apple pomace each year (25–30% of fresh fruit weight), most of which goes to landfill and breaks down into methane (with 25 times the warming potential of CO₂). We rescue it and turn it into fibre.

Material Lifecycle
From apple, to handbag.
Four stages, from pomace recovery to fibre leather-making, the spunlace backing and workshop inspection. Every step is visible.
Apple Pomace · Recovered Waste
The global juicing industry produces about 4 million tonnes of apple waste each year (25–30% of fresh fruit weight), most of which goes to landfill and breaks down into methane (with 25 times the warming potential of CO₂).
We rescue it from the waste stream, then low-temperature dry and grind it into apple fibre.
Bio-Leather · Plant-based
Apple fibre and plant-based fibres are blended with PU resin, with radiocarbon testing (ASTM D6866-22) confirming 69% biobased carbon content and USDA BioPreferred certification.
Spunlace · Hydroentanglement
The backing uses spunlace technology, mechanically entangling fibres with high-pressure water jets, with zero chemical binders and zero glue. Paired with natural fibres, the whole material is fully biodegradable.
Workshop QC · Inspection
Every hide is inspected at the workshop for evenness, flexibility, texture and water resistance.
Any hide that does not meet standard is rejected in full.
Environmental Impact
Where the impact actually is.
01
Waste-to-Material
Each year 4 million tonnes of apple pomace go to landfill worldwide, breaking down into methane (with 25 times the warming potential of CO₂). For every kilogram of apple waste our supplier uses in place of PU, about 5.28 kg CO₂ of emissions are saved.
02
Water Saved
Raising and tanning 1 kg of animal leather takes about 17,100 litres of water (the equivalent of 70 bathtubs). Cowhide uses 14–24 times the water of synthetic leather. Apple leather uses PU as its carrier, so its water use is similar to synthetic leather, lowering the overall water footprint by about 95%.
03
No Chrome Pollution
About 90% of animal leather worldwide is chrome-tanned, and hexavalent chromium (Cr⁶⁺) is classified by the International Agency for Research on Cancer as a Group 1 carcinogen. This material has hexavalent chromium of < 3 PPM, meeting the EN71-3 infant safety standard.
04
Lower Earth Impact
Apple leather fully breaks down in about 300 days in soil and about 900 days in marine environments, and the waste can be converted into organic fertiliser. Standard PU is hard to degrade and continuously releases microplastic fibres in use.

Care
How to use it, so it lasts longer with you.
The base of apple leather is PU resin blended with 69% plant fibre.
Unlike animal leather, it does not need conditioning oils or wax;
unlike plastic, it dislikes prolonged soaking and sun exposure. Here are practical tips for using this material.
4 Practical Habits
1
Everyday wipe: dry or damp cotton cloth
Wipe dirt gently with a lightly damp cotton cloth. If needed, use a tiny amount of a mild neutral cleanser (such as baby wash) diluted in water, wipe gently, then dry immediately with a dry cloth.
2
If it gets wet: blot and air-dry
The PU base is water-repellent, so just blot raindrops away. If a large area gets wet, blot with tissue, then let it air-dry in a cool, ventilated place. Do not use a hairdryer or hot air.
3
Storage: breathable cotton bag, lightly stuffed
Store it in a breathable cotton bag (not a plastic bag, which traps moisture and causes mould). Stuff it lightly with soft padding to keep its shape and avoid deformation from long-term pressure. Keep the storage area dry and ventilated, away from heaters and kitchen fumes.
4
Keep out of direct sun
Brief sun exposure is fine, but avoid prolonged exposure (over 8 hours). UV light accelerates ageing of the PU base, dulling and hardening it.
5 Things Not to Do
✗
Do not use alcohol, disinfectant or chemical solventsNo alcohol, disinfectant or solventsthey damage the PU surface coating
✗
Do not use a hairdryer or hot airNo hairdryer / hot airPU is heat-sensitive and will blister and deform
✗
Do not use regular animal-leather conditioning oils or waxNo leather oils or waxPU does not need oil conditioning and will absorb unevenly, leaving blotches
✗
Do not seal it in a plastic bagDon't seal in a plastic bagpoor ventilation traps moisture and causes mould spots
✗
Do not soak it in water for over 30 minutesDon't soak over 30 minthe plant fibres will swell and deform
