Three Gloucestershire companies have joined forces to produce a "green" coffin made from newspapers.
It was the idea of undertaker Jeremy Clutterbuck, who said he spent years searching for a "truly eco-friendly" casket.
He joined forces with a local paper mill and a firm that makes bespoke timber items to create the new company, called Sunset Coffins.
The firm said: "People are thinking of the environment, even in death."
Environmentally-friendly burials have become increasingly popular, with actress Lynn Redgrave, chef Keith Floyd and Body Shop founder Anita Roddick being buried in "eco-friendly" coffins.
'Creak, squeak and leak'
The company is based in Cam, near Dursley. A spokesman said the coffins were made from "very strong board".
He claimed wicker coffins, which are also described as eco-friendly, were known as "creak, squeak and leak" in the industry.
And he said that cardboard coffins "had been known to collapse during funerals".
It takes 70 recycled tabloid newspapers or 120 broadsheets to make one biodegradable coffin, the company said.
Spokeswoman Gillian Winstone said the coffins had been used by Mr Clutterbuck's customers in several cremations during testing and at least two people had already been buried in them.
She said: "An environmental lifestyle is something that's here to stay.
