A deposit-refund system (DRS), also known as deposit-return system, advance deposit fee or deposit-return scheme, are systems that add a surcharge on a product when purchased and a rebate when its packaging is returned. A well-known example is when container deposit legislation mandates that a refund is given when reusable packaging is returned. A DRS is a market-based instrument to address externalities, similar to a pigovian tax, with the key difference that a DRS refunds the fee after the product is returned. [1] This provides an incentive to consumers to properly dispose of a product.

While most commonly used with beverage containers, DRS can be used on other materials including liquid and gaseous wastes. [2] A DRS is used on products such as batteries, tyres, automotive oil, consumer electronics and shipping pallets.
There are three potential advantages of a DRS: it reduces illegal dumping by giving a financial incentive, it makes monitoring and enforcement easier, and evading the costs is difficult. [1]
A potential disadvantage is, that DRS can focus on the collection of single-use beverage packaging and replace systems for multi-use packaging return systems (for example in Germany) [3] .
DRS is said to be based on the principles of Extended Producer Responsibility. [4]
DRS can be either voluntary or mandated by legislation.
