What is a bottle bill?
Around the world, demand is growing for countries to increase their recycling rates for bottles and cans as a means to fight litter, ocean plastic, and reduce recycling costs. Learn more about what bottle bills are and how they work to ensure container recycling.
By Michael Noel, Governmental Affairs Manager, TOMRA
Every minute, one million plastic bottles are bought around the world, and that number is only projected to increase. 86% of all plastic packaging is buried, burned or leaked into nature, polluting our communities and the world's oceans. In fact, the equivalent of one garbage truck of plastic ends up in our oceans every minute. This volume of plastic waste is so enormous that, by 2050, scientists estimate there will be more plastic in the ocean than fish (by weight).
With this vast scale of plastic bottle production and consumption, how can we reduce, and ultimately prevent, the negative impact that beverage container waste has on the planet? How can we recycle this material and others effectively, and how can we encourage people to return their used bottles and cans for recycling in the first place?
An increasingly popular, but far from new, solution is bottle bills – also referred to as container deposit systems or deposit return schemes – typically established through legislation passed by state or national governments. These programs achieve a collection rate for beverage cans and bottles almost three times that of states without such systems.1 In fact, TOMRA’s reverse vending machines (which automate the collection of containers for recycling) capture over 40 billion used beverage containers across 84,000 installations worldwide each year.
Here’s a simple guide to bottle bills and why they are so successful for collecting, and ultimately recycling, used beverage containers.
What is a bottle bill and how does it work?
Bottle bills work by adding a small deposit on top of the price of a beverage – such as those in plastic and glass bottles and aluminum cans – which is refunded to the consumer when they return the empty bottle or can for recycling. Think of it as buying the beverage, but borrowing the container!
Bottle bills have been around for several decades, but the concept has been used for refillable containers for even longer, particularly for glass collection. Today, these programs are in place in over 60 regions around the world, including 10 US states, with the additional deposit value on drink containers ranging from approximately $0.05 to $0.38.
To make the wide-scale return of bottles and cans more efficient and convenient, many bottle bill programs use automated “reverse vending machines” to analyze, sort, and compact containers when they are collected for recycling and reuse. Reverse vending machines instantly count the number of containers returned, sort away non-deposit / ineligible containers, initiate billing with beverage distributors and pay out the correct deposit refund to recyclers – much faster and more reliably than is possible through manual counting.
Reverse vending machines are usually conveniently located at retail locations, allowing users to receive their refund in cash or as vouchers they can use in-store. In some countries, it is also possible to donate the deposit refund to charity directly from the reverse vending machine.

Why are bottle bills successful?
There are two main reasons container deposit schemes succeed in increasing recycling rates and reducing plastic waste.
- Financial incentive: Bottle bills provide a financial incentive for consumers to return bottles and cans that might otherwise be littered or thrown in the trash. Giving a financial value to these empty containers means they are viewed and treated not as trash, but as a resource. In fact, deposits reduce beverage container litter by 40% or more. The results of the financial incentive are clear. For example, while the U.S. national recycling rate has stagnated for decades at around 34%, high-performing deposit return systems routinely collect 90% or more of containers for recycling.
- Increased purity: By separating bottles and cans for recycling through reverse vending machines, drink containers are collected without contamination from other types of waste that may be in a household recycling bin. This ensures containers can be recycled into new bottles and cans, rather than used for lower quality applications like landfill cover. This is a process known as closed-loop recycling, which TOMRA calls the Clean Loop. Clean Loop Recycling reduces the reliance on raw materials needed to produce new beverage containers (that is, coming into the loop) and waste ending up in landfills or in nature as litter (going out of the loop).
How bottle bills work around the world
Many countries around the world operate these programs. Bottle bills can result in nearly 100% of all beverage containers returned for recycling; no other waste collection system comes even close to such high return rates.
- Michigan: Michigan has the highest return rate of any U.S. state with a bottle bill, at around 90%. The $0.10 deposit value is a proven motivator for consumers. In the first 40 years of its history, the bottle bill incentivized Michiganders to collect 96% of the 150 billion containers sold with a deposit.2 And the program remains popular. 94% of voters say they support the deposit law.3
- Norway: Norway has long been recognized as a trailblazer in container deposit return systems, with countries around the world replicating its model. Renowned ocean plastic waste researcher Dr. Jenna Jambeck even pointed to the Norway system as a model deposit program for reducing coastal beverage container litter.4 Starting with TOMRA’s first innovative reverse vending machines in 1972, return rates in Norway today are at 89% for both cans and plastic bottles, with collections managed by program coordinator Infinitum.
- Germany: The German market outperforms the rest of the world in beverage container recycling results, following the introduction of its bottle bill in 2003. Germany’s collection rate is extremely high, with approximately 98% of all plastic bottles returned (and 99% for cans).
- Lithuania: Lithuania introduced its bottle bill in 2016, with the aim of reducing litter, cutting local government costs and boosting recycling rates. Prior to the introduction of the program, only a third of plastic bottles were collected (34%). Two years later, the country’s deposit initiative, which is powered by TOMRA’s reverse vending machines, has seen return rates increase to 92%.
Calls are increasing around the world for other countries to follow suit, with the United Nations Environment Agency in 2017 encouraging all nations to implement container deposit schemes. The Single-Use Plastics Directive adopted in 2019 by the European Union has set a target for member states to collect 90% of all plastic bottles by 2029, which experts say is difficult to achieve without a container deposit system. Regions such as Scotland, Portugal, Slovakia and more states in Australia are set to introduce bottle bills in the next few years.
With our planet facing a waste crisis, we need to live more sustainably and recycle more efficiently. TOMRA’s is committed to making this vision a reality by changing consumer behavior for the better. As these examples show, bottle bills are a proven part of the solution to changing the way the world thinks about waste. When the right waste management system is in place, people can be empowered to lead a resource revolution.
