Why Aluminum Cans?

Why Aluminum Cans?

Recently, the 2010 aluminum can recycling rate was announced. Americans recycled approximately 56 billion aluminum cans last year, increasing the recycling rate to 58 percent – saving the energy equivalent of 17 million barrels of crude oil, or nearly two days of all U.S. oil imports. Consumers recognize the value of infinitely recyclable aluminum cans – recycling it is one of the easiest ways consumers can help reduce their environmental footprint. Consider:

  • Cans have the highest recycling rate of any beverage container in the U.S., far higher than glass and plastic.

  • The average aluminum can is made from 68 percent total recycled content, the highest of any beverage container.

  • Cans provide long shelf life by protecting products inside from light, oxygen and other factors which can affect taste and even product safety.

  • Cans don’t shatter and are among the lightest beverage packages to transport, reducing their environmental footprint.

  • Cans go from the recycling bin to store shelves within 60 days.

  • Making cans from recycled metal takes 95 percent less energy and 95 percent less greenhouse gas emissions than using new metal.

  • The aluminum can is the only package that more than covers its recycling costs, helping to finance the collection and recycling of other materials such as glass and plastic.

Recent life cycle analyses of the aluminum beverage can in the U.S. and in Europe confirm the can is more sustainable than ever, a consumer-friendly packaging material for beverages. As the largest beverage can maker in the world, Ball Corporation continues to work with our partners throughout the supply chain to drive the recycling rate higher, ensuring the aluminum can remains the sustainable package of choice.

The Aluminum Can Advantage

Key Sustainability Performance Indicators for the Aluminum Can

Aluminum cans are the most sustainable beverage package on virtually every measure. Aluminum cans have a higher recycling rate and more recycled content than competing package types. They are lightweight, stackable and strong, allowing brands to package and transport more beverages using less material. And aluminum cans are far more valuable than glass or plastic, helping make municipal recycling programs financially viable and effectively subsidizing the recycling of less valuable materials in the bin.

Most of all, aluminum cans are recycled over and over again in a true "closed loop" recycling process. Glass and plastic are typically "down-cycled" into products like carpet fiber or landfill liner.

Following are a series of key sustainability performance indicators highlighting the sustainability performance of the aluminum can for 2016. You can download the full report including detailed methodology here.

Industry Recycling Rate

An indicator of stewardship of the metal, the industry recycling rate shows how much aluminum can scrap (including imported and exported cans) the industry recycles as a percentage of U.S. shipments. This rate has grown dramatically since it was first reported in 1972 at 15.4 percent.

In 2015 the industry recycled 56.8 billion cans for an industry recycling rate of 64.3 percent, a slight decline from 2014 but well above the ten-year average of 60.4 percent. This reflects nearly 57 billion cans recycled. The rate declined as the volume of used beverage containers recycled by the industry dropped about 4 percent in 2015, a likely consequence of a drop in scrap prices year-over-year.

Consumer Recycling Rate

The consumer recycling rate for aluminum cans, which measures domestic consumer recycling behavior, was 54.5 percent in 2015, a 2-point drop year-over-year but higher than the 10-year average rate of 51.7 percent.

This rate helps track the effectiveness of consumer recycling programs and also allows a direct comparison of recycling rates for aluminum versus glass and plastic. Aluminum cans are by far the most recycled beverage package in the United States with a 13 to 24 point recycling rate advantage against glass and plastic.

Recycled Content

Aluminum cans are unique in that they are most often recycled directly back into themselves meaning that the average can has a very high percentage of recycled content. This means that aluminum cans have more than 3X the recycled content than EPA estimates for glass or plastic, with 70 percent recycled content on average.

Since it takes just 8 percent of the energy to produce aluminum from recycled material versus producing new aluminum, high recycled content is a good indicator of the can’s environmental footprint. The recycled content calculation includes metal from both post-consumer and post-industrial scrap sources and complies with ISO reporting standards.

Value of Material

Aluminum cans help make municipal recycling programs possible. Many such programs rely on re-selling recycled material and the high value of aluminum in the recycling stream effectively subsidizes the recycling of less valuable materials in the bin. The report finds that aluminum can scrap is worth $1367 per ton on average versus $310 per ton for plastic (PET) and $0 per ton for glass.

The data reflects an average price for recyclable materials from February 2014 – February 2016. The implications are clear -- without aluminum, very few curbside pickup programs would be financially viable.


A strong indicator of material management and industrial efficiency, the weight of the average aluminum can has declined significantly – 38 percent – since tracking began in 1972. After all these years, can makers continue to innovate, making more cans with less metal while maintaining strength and durability.

Lighter cans mean better shipping efficiency and less waste. Aluminum cans are more than 15X lighter than standard glass bottles, allowing brands to package and transport more beverages using less material.

Aluminum Can Recycling Through the Years

The aluminum industry was an early pioneer in reporting an annual recycling rate for one its key products -- the aluminum beverage can. In 1972, when an industry recycling rate was first published, it was a mere 15.4 percent.

Following a period of decline from the mid-1990s to early 2000s, both industry and consumer recycling of aluminum cans have grown significantly. Since the early 2000s, both the industry and consumer recycling rate for the aluminum beverage can have risen around 10 to 15 points and held near these levels for the past five years.

Use Phase: Transportation & Refrigeration

A 2016 study by ICF International found that the combined greenhouse gas (GHG) emissions associated with the transportation and refrigeration of beverages in aluminum cans are lower than those associated with beverages in glass or plastic bottles under the same conditions. You can download an infographic on the full report here.

On a per liter beverage basis, emissions associated with transporting and cooling aluminum cans are 7 to 21 percent lower than plastic bottles and 35 to 49 percent lower than glass bottles, depending on the size of the comparative bottles as well as the types of refrigerators in which beverage is cooled prior to consumption. On a per container basis, the associated emissions of beverage packaged in a 12-oz aluminum can is 45 percent lower than in a 12-oz glass bottle and 49 percent lower than in a 20-oz plastic bottle when delivered and chilled in small markets and convenience stores.

The study analyzed the standard serving size for each container, which can vary, as well as a per-ounce equivalent . In both scenarios, the shape, dimensions, weight and material of the aluminum can offered higher packaging and cooling efficiencies that resulted in less energy needed and lower emissions. Noted Marian Van Pelt, Vice President at ICF International: "Across all scenarios studied, aluminum has lower associated use-phase emissions than comparable glass or plastic containers."

More Can Be Done

While the aluminum beverage can is by far the most recycled and recyclable beverage container on the market today, more can be done to increase can recycling in the United States. Each year nearly 40 billion cans – $800 million worth of aluminum – end up landfills, a major loss to the economy and the environment. Making a can from recycled aluminum saves 92 percent of the energy required to make a new can.

The energy saved by recycling 100 percent of aluminum cans could power 4 million homes for a full year. The Aluminum Association engages in educational activities and advocacy efforts to drive increased recycling of aluminum across the supply chain.

Several of our member companies also participate in the Recycling Partnership, a multi-material coalition of businesses active with local municipalities to improve residential curbside recycling programs and infrastructure.
