Supermarket giant Coles plans to transition away from single-use plastic bags by July 1 and the company has been been digging for designs to grace its new reusable varieties.

They asked primary and secondary students to send in designs and Brandi Li’s was among 14 selected.

Brandi’s design will feature on a large shoulder bag, which will help raise funds for SecondBite. It has also earned her school $5000 for a sustainability project.

“I feel really proud of being able to help my school,” Brandi said.

“It was a great day at Coles and they made us all feel very special. All of the designs were amazing.

“I feel really happy that my bag is supporting SecondBite because they stop good food from going to waste and it goes to people that need it.”

SecondBite CEO Jim Mullan said the food relief organisation was delighted to receive 20 cents from the large re-usable shoulder bags.

“The money raised will support the work of SecondBite and helps to fund the collection of surplus food, the sorting, storage and redistribution to community food programs right around Australia,” he said.

“For every large shoulder bag that’s sold at Coles for $2, we will be able to provide the equivalent of a meal to a person in need.”

Other student winners represented communities across the country from the remote town of Kaniva in Victoria’s Wimmera to suburban Melbourne and Sydney, the north and south coasts of New South Wales and Perth.

The winners ranged in age from eight to 17 years and the themes of the designs include flowers, fresh fruit and vegetables, fish, the sunset and forest.

The winning designs will be applied to four different types of durable, multi-use shopping bags including a shoulder bag, a chiller bag, a tote and a jute bag - with the first series going on sale from World Environment Day on June 5.

They are designed to be used over and over again and be returned at the end of their lives to recycling bins at Coles stores.

Coles Managing Director John Durkan said the sale of reusable bags were a win-win for the environment and for community organisations.

“The wonderful efforts of these budding artists will be seen and appreciated by millions of customers who shop at Coles each week.”

The announcement coincided with Clean Up Australia Day Last Sunday, when thousands of Australians took to their local park, beach, bushland and streets to clean up their local environment.
