The people behind the UK's first crisp, compostable packages say consumers should pressure big corporations for greener packaging.
Sean Mason and Mark Green launched Two Farmers last year. Its chips are made on the same farm where the potatoes are grown near Ross-on-Wye in Herefordshire.
Its crunchy packages are made of eucalyptus derived cellulose film. They break within 26 weeks in a household compost bin.

Two farmers make 7,500 packages a day and supply local shops and pubs.
But each bag costs about 11p more than the standard package, which means it can be hard to convince stores to store them.
Mason said they try to absorb some of the deficit but are still rejected by the retailers they approach.
"I think it's purely low priced," he says.

"They love what we are doing, we send samples, they love the flavors, they love the texture of the chips, they love the packages, they love the story about us and then they come back to us and say" we're actually buying such a brand and chips and we paid 6p per pack less "."
Green believes cost is the main reason why large companies are not using fully compostable packaging.
Two Farmers is headquartered in Herefordshire, where potatoes are grown and chips are made.
"It's the consumers who will have to demand it," he says.
"They need to go to the local store or the diner or wherever they buy their chips and require that packaging or ask the store to stock it."
Another small leader in eco-friendly packaging is Delphis Eco, which produces cleaning products.
Founder and CEO Mark Jankovich told Sky News: "All we do is be as sustainable as possible.
"What goes into the bottle is green. The label is green – we use vegetable paint so there's no water in the process and the next thing we need to think about obviously was plastic and packaging, so we did a huge amount of work there too. .
"I believe we are the only company in the UK to have 100% recycled plastic in all its packaging."

With small businesses proving that single-use plastic packaging is possible, why didn't large companies do the same?
Walkers, a British chips maker, which sold 15 million packets of chips last year, says it is investigating "all options" around packaging and recycling.
A spokesman said: "Our current focus in the UK is on the development of recyclable packaging that will be accepted as part of the kerbside collections and moving recycling boxes.
"We believe this is the most sustainable option for the UK in the long term as it would allow material reuse rather than relying on single use materials. In the meantime, we have the Walkers recycling scheme that collects used packaging and reuse. plastic in other ways. "
Coca-Cola says the amount of recycled material in its plastic bottles will double from 25% to 50% by March next year.
Julian Hunt of Coca-Cola told Sky News: "I think we really appreciate the innovation that is now happening in the food and beverage market around packaging.
"We know this is something that really worries consumers and businesses of all sizes are meeting this challenge."
