The material needs to be tested by a trustworthy source for safety, but this invention could represent an advance that would drastically reduce the harms (such as the contaminants in the plastic) caused by the water bottles.
A British scientist claims to have invented a plastic-free, single-use water bottle that can decompose within three weeks.
The Choose Water bottle, developed by James Longcroft, aims to replace plastic bottles and help save the world’s oceans from plastic waste.
The outer lining of the bottle is made out of recycled paper donated by businesses, while the waterproof inner lining is made with a composite material Longcroft has developed himself.
All the constituents of the bottle can fully decompose within three weeks when left in water or landfill, and can be eaten by sea creatures, the company told Business Insider in a statement.
The steel cap on the bottle will also rust and fully decompose in about a year, Longcroft told the Evening Standard.
Plastic usually takes hundreds of years to break down.
Longcroft, who lives in Scotland, is still waiting for patents and started crowdfunding for the bottle on Monday. He has set a goal of £25,000 ($US34,000), of which he has raised about £8,000 ($US11,000) so far.
He hopes to see the bottles available in stores by the end of the year, and that they will be sold for about 85p and 90p (about $US1.2) so that they become a viable alternative to plastic, according to The Times.
