New Zealand startup Materially Kiwi is in preliminary talks with automotive giants BMW, Rolls Royce, and Volkswagen to integrate its plant-based leather alternative into vehicle interiors. Founded by Shelley Houston, the company processes rejected kiwifruit—fruit deemed too imperfect for export—into a durable, plastic-free biomaterial. Currently, 80 national and international brands are pursuing partnerships with the firm as the fashion and automotive industries shift away from traditional animal-derived leather.
How is kiwifruit transformed into leather?
The manufacturing process relies on extracting high levels of cellulose and polysaccharides from discarded kiwifruit. According to Dr. Angelique Greene of the New Zealand Institute for Bioeconomy Science, the team engineers these organic compounds to balance toughness with flexibility. The transformation begins by breaking down the fruit’s structure, a process that required at least 15 to 20 experimental attempts before achieving a viable, durable sheet.
The material is so convincing that trade show attendees often attempt to eat it. Materially Kiwi has had to post signs at events explicitly asking visitors not to consume the samples.
Why are automotive brands seeking plant-based alternatives?
Major manufacturers are facing pressure to meet sustainability pledges, prompting a move to eliminate animal-derived products from their supply chains. While traditional synthetic “vegan leathers” often rely on plastic polymers, Materially Kiwi has prioritized a plastic-free composition. The primary technical challenge, according to Dr. Greene, was ensuring water resistance without using synthetic polymers. The research team eventually developed a method using sustainable molecules to ensure the material remains durable in real-world conditions.

What are the production targets for commercial viability?
The current yield ratio stands at one kilogram of kiwifruit for every one square metre of material. Shelley Houston confirmed that the company is planning a pilot factory in the Bay of Plenty, a region chosen for its proximity to the kiwifruit supply chain. Scaling this process remains the primary focus, alongside refining the material’s long-term breakdown profile to ensure it remains non-toxic once it reaches the end of its lifecycle.
Comparison: Synthetic vs. Biomaterial Leather
| Feature | Synthetic Leather | Materially Kiwi |
|---|---|---|
| Base Material | Petroleum-based plastics | Kiwifruit cellulose |
| Sustainability | Low (Non-biodegradable) | High (Waste-to-product) |
Frequently Asked Questions
- Is the material actually made from kiwis?
- Yes, it utilizes rejected kiwifruit that is unsuitable for the export market, turning waste into a functional biomaterial.
- Does the material contain plastic?
- No. A key technical requirement for the company was to avoid synthetic polymers, relying instead on engineered cellulose and polysaccharides.
- What can this material be used for?
- Current applications include handbags, clothing, and potential use cases for automotive interiors and industrial conveyor belts.
