Deposit-refund schemese are a great way of increasing reuse. They create the financial incentive for reusing. A great example of this are restaurants that support returning a takeaway container or bringing your own containers. Often they simply pass the cost of the container to you, giving you the choice on whether they wish to pay for the convenience of not bringing the packaging. You can make a difference by patronising your local takeaways who support such a policy, suggesting they do, or asking if you can bring your own container. I’ve attached a restaurant that does just this, though unfortunately it’s not from Australia.
