WA accelerates plan to ban single-use coffee cups by 2023 Source: Unsplash/Dan Burton. Plastic coffee cups and lids designed to be used once will be a thing of the past for Western Australians by within two years as part of the state’s plan to accelerate its action on single-use plastic. The WA ‘Plan for Plastics’ will be fast-tracked by four years with a view to phase out single-use plastic items such as bowls, cups, plates, cutlery and polystyrene food containers by the end of 2021 as part of stage 1. Helium balloon releases will also be phased out by this year and single-use coffee cups by 2023 as part of stage 2 of the plan.
