Coles is encouraging customers to reduce food and plastic waste at home with its latest promotion, which is this time aimed at adults.

The Coles Fresh Food Container Program, offers ‘container credits’ when customers spend $20 or more using flybuys online or in-store.

The credits can be redeemed for a range of five reusable containers from 600mL to 1.5 litres, as well as a specially-designed vacuum pump. The containers are made from durable polypropylene and can ultimately be recycled in a kerbside bin at the end of their life.

“We know our customers want to reduce food waste for environmental and family budget reasons, and these reusable containers are a great way to keep food fresh in the fridge or pantry without the need for more single-use plastic,” Coles chief operating officer Greg Davis said in a statement.

The supermarket giant has removed 1.2 billion single-use plastic bags from circulation since they were phased out last year and has diverted more than 542 million pieces of flexible plastic from landfill since 2011 through its recycling partnership with REDcycle.

“This is a great initiative by Coles to reduce food and plastic waste. When food waste ends up in landfills it produces methane – a powerful greenhouse gas that contributes to climate change. By shopping wisely and storing food in air tight reusable containers we can all do our bit to help the environment and save money, ” Paul Klymenko, CEO of environmental organisation Planet Ark, said.

The promotion is available in-store  running between April 24 and July 2.
