Waste & Metal Recycling
RWM & Letsrecycle
Ocean plastic pollution, waste management costs and mandated collection targets are causing more and more governments to make sustainable resource management a priority. One policy that is actively being discussed is the concept of giving waste a value, to incentivize the public to collect it for recycling. This is a particularly popular approach for the items that are most commonly littered and found in oceans, such as beverage containers. Container deposit return systems (or “bottle bills”) add a deposit on the container on top of the price for the beverage, which is repaid when the consumer returns it to be recycled. A number of states or countries have committed to update existing deposit systems or develop new systems. In this ongoing article series and its white paper, "Rewarding Recycling: Learnings From the World's Highest-Performing Deposit Return Systems", TOMRA explores the best practices that separate the leaders in deposit return systems from the laggards.

The term “deposit return” is made up of two distinct but inseparable parts: the deposit value that engages the consumer, and the actual return of beverage containers for recycling. High-performing deposit return systems make the return and redemption of containers easy for the consumer, by making it as accessible as it was to purchase the beverage in the first place.
“Return to retail” refers to a feature of deposit return legislation whereby retailers who sell beverages are also required to take back empty containers for recycling. All the major high-performing deposit return systems utilize return-to-retail collection, achieving an average return rate of 92%.1 In 2019 the average return rate for deposit systems with return-to-retail obligations was 88%, compared to 77% in systems in which retailers are not involved.2
When consumers are charged a deposit on a container, a promise is made that they will be able to recoup their money. It is the obligation of producers, retailers and the government to ensure this is possible, otherwise the deposit risks becoming an unauthorized tax or eco-fee. Effective deposit return systems not only consider cost effectiveness in the design of a DRS, but also the consumer’s experience and rights. This is what a return-to-retail network delivers.
High-performing systems do not allow design of collection point infrastructure and operations to be left to a central beverage industry-run administrator, due to potential conflicts of interest. The design of a redemption system design is either put in place at a legislative level (for example, a return-to-retail model) or an independent “network operator” is tasked with the specific system requirements, such as the number of collection points per capita, to split responsibility for system administration into two levels.
Although a metric for “convenience” does not exist yet in statute, high-performing programs are effectively providing consumers convenient locations to return their containers in parallel with retailer density. As data suggests below, a ratio of 1 point of return for every 355 – 1,100 people is effective. However, in areas with higher urban populations, deposit systems take a different approach in order to meet demand. In Norway, for example, the number of collection points per square kilometer is 0.3, but in the capital Oslo it is 11. Other metrics used to evaluate convenience include the return rate for the deposit return system, and the percentage of consumers that participate in the system.
Container compaction provides important value within deposit systems. When compacted or crushed, PET bottles are reduced in size to a ratio of about 2.5 : 1 and aluminum cans 6 : 1. This reduction in size saves space, reducing transportation costs and minimizing the risk of unauthorized redemption since crushed containers cannot be redeemed twice. The closer container compaction occurs to the point of redemption, the more fuel, carbon and money saved. As such, Norway and Sweden incentivize the use of RVMs that can compact containers by paying a higher amount to retailers who utilize such technology (by way of a higher “handling fee”).
In most circumstances, retailers are paid what is known as a handling fee for their redemption services and, in high-performing systems, this is paid by the Central System Administrator (which is funded by the beverage industry) to the retailer on a per-container basis.3
Consumers may return deposit containers to any retailer in the network (known as “universal redemption”), and retailers take back containers similar to the types they sell. This benefits both retailers and consumers.
Retailers below a certain size might not be obligated to participate but can offer redemption services if they wish.
These locations provide deposit container collection alone and can play a role in redeeming containers by:
Consumer’s perspective
Government’s perspective
Producer’s perspective
Retailer’s perspective
Michigan, USA
Michigan’s DRS has collected 96% of the 150 billion deposit containers sold since its DRS was introduced more than 40 years ago.14 The state offers retailers provisions such as limiting the number of containers that any one consumer can redeem per day (250) and only requires retailers to take back brands that they sell (though the latter can cause consumer confusion). This aims to help retailers manage the redemption volume while providing consumers with convenient access to redemption. A 2019 poll showed that 94% of Michigan respondents supported the deposit law.15
Norway
Across Norway, there are 15,000 redemption locations, equating to one redemption point for every 355 people.16 Of those locations, only 23% utilize RVMs; however, these account for the collection of 93% of returned containers. These RVMs allow the Central System Administrator, Infinitum, to make the transportation network as efficient as possible, due to container compaction and redemption data that predicts pick-up routes. In 2020, Norway achieved an 92% container return rate.17
California, USA
California is a perfect example of the impact of inconvenience on recycling performance. The state’s deposit system was built on a network of redemption centers, with no redemption obligations for retailers. Retailers are only obligated to redeem containers if their store is not located near a redemption center (or if a redemption center closes down, as is now the case).
Retailers can also opt out of redemption by paying US$100 (€88) per day, but this is largely unenforced. A rigid and outdated state funding formula has left redemption centers starved for cash, while at the same time materials prices plunge (which redemption centers are entitled to) and operating costs including minimum wage rise.
This has caused recycling centers to close en masse since 2013. Closures have left California with 1,219 recycling centers, less than half the 2,578 centers that were in operation in 2012.18 San Francisco has only one center to serve nearly 900,000 residents.19
Consumer convenience for redemption is key. The result is that Californian consumers have lost convenient access to a deposit redemption point, making deposits difficult to redeem and essentially turning the deposit into a tax. The deposit program’s recycling rate has fallen from 74% in 2013 to 62% in 2020 (which includes cans and bottles placed in curbside recycling bins).20
High-performing programs successfully engage consumers with a meaningful deposit value, but they also make returning containers as easy purchasing the beverages in the first place, to promote high collection rates. Given that the world’s highest performing programs utilize retailers in the return of containers, it’s clear this is a proven model for success. In addition, leveraging existing infrastructure helps governments and producers reach collection targets quickly and cost effectively. Flexibility for retailers, in the form of a healthy handling fee and varied redemption obligations (depending on size), promote fairness in the system. In this way, high-performing deposit return systems balance stakeholder interests while achieving superior recycling rates.

1 The top 10 highest-performing container deposit systems in the world as of 2019 are, in order: Germany (98%), Netherlands (95%), Finland (93%), Denmark (92%), Lithuania (92%), Palau (90%), Norway (89%), Croatia (89%), Michigan (89%), and Estonia and Iceland are tied with at 87%. All employ a return-to-retail model, with the exception of Iceland and Palau, which utilize a return-to depot model in part due to their extremely small populations and minimal retail infrastructure. “Global Deposit Book 2020,” Reloop. 2020.
