Supermarket giant Coles has announced its plans to stop selling single-use plastic tableware and cutlery.

Shops nationwide will stop stocking plastic products, including cups, plates, straws and bowls by July 1.

This is part of a massive effort to stop the amount of single-use plastic that ends up in landfill, with the move predicting a reduction of plastic by 1.5 million kilograms a year.

Clean Up Australia Chairman Pip Kiernan praised Coles for the effort.

"Too many of these items end up in our parks, waterways, beaches and roadsides and if left there damage our precious environment for hundreds of years, outliving all of us," Ms Kiernan said to 9News.

"We applaud Coles for listening to their customers and taking the lead in replacing these single use plastic items."
