Food company Kraft Heinz and sustainable packaging firm Pulpex are working on development of a paper-based ketchup bottle.
It would be made of sustainably sourced wood pulp, and according to the companies would be fully recyclable.
Heinz and Pulpex are currently working on a prototype to test how a fibre-based bottle would work with tomato ketchup.
The next stage will be testing the prototype to assess performance, before testing it with consumers before full launch on the market.
Kraft Heinz chief executive Miguel Patricio said: “Packaging waste is an industry wide challenge that we must all do our part to address.
“That is why we are committed to taking steps to explore sustainable packaging solutions across our brands at Kraft Heinz, offering consumers more choices.
“This new Heinz bottle is one example of how we are applying creativity and innovation to explore new ways to provide consumers with the products they know and love while also thinking sustainably.”
