Cargill Enterprises would pick up soft plastics from stores, which would be baled and palletised by Waste Management.
Those would be backhauled by Cottonsoft to Christchurch, then to Auckland by Goodman Fielder.
It was important the scheme was integrated into existing distribution networks, in order not to be adding an additional layer of carbon costs, Langford said.
The soft plastics would ultimately be manufactured into fenceposts for farms, vineyards and gardens by Future Post, which was seeking to expand its operations due to high demand.
The packaging forum was ultimately looking to expand the scheme nationwide, Langford said.
Soft plastic recycling would be available at eight participating Countdown, New World and The Warehouse stores in Dunedin.
