Finnish forestry firm Stora Enso said on Tuesday it would start supplying pulp for sustainable packaging company Pulpex, a research and development venture of British beverage maker Diageo.
Stora Enso and Pulpex will also work together to build a scalable high speed production line for bottles and other packages out of pulp fibre in a commercial capacity in 2022, the companies said in a joint statement.
"The first high-speed line will be a demonstrator to show whether we can do this on an industrial scale and at the cost level we are expecting," said Sohrab Kazemahvazi, senior vice- president of Stora's formed fiber unit.
In addition to Diageo's brands, Pulpex said it was working with Pepsi, Unilever, GSK and Castrol, which are committed to together produce 750 million paper bottles in a year.
The bottles are made by molding the pulp directly into shape, skipping the step of first making it into a flat board, Kazemahvazi told Reuters. The bottle is then lined with plastic but will still fit into the paper waste stream, he added.
"We use no PET barrier and if we use plastic, we want to keep the bottles recyclable and in case they end up in Nature, biodegradable," Kazemahvazi said.
Last July, Diageo said it would test the Pulpex bottle by launching Johnnie Walker whisky in a paper bottle in 2021.
