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.

The U.S. aluminum industry is committed to growing can recycling. Learn more about our ongoing work to improve recycling rates in the Every Can Counts: An Aluminum Beverage Can Recycling Manifesto here

Following are a series of key sustainability performance indicators highlighting the sustainability performance of the aluminum can in 2019.

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 2019, the industry recycled 42.7 billion cans for an industry recycling rate of 55.9 percent, a decline from 63.6 percent in 2018. This change was driven largely by production shifts within the industry in 2019.

Consumer Recycling Rate
The consumer recycling rate for aluminum cans, which measures the amount of domestic aluminum can scrap recycled as a percentage of cans available for recycling, dropped to 46.1 percent in 2019, lower than the 2018 rate of 49.8 percent but above the 2017 number of 45.1 percent. The 20-year average for the consumer recycling rate is around 50 percent. Aluminum packaging represents only 3 percent of the weight but nearly half of the economic value of recyclable material generated by a typical single-family home. 

The rate provides a snapshot of how well municipal recycling programs are performing nationwide though it can still be impacted by year-to-year fluctuations in metal flows and commodity prices.

Aluminum cans remain by far the most recycled beverage package in the United States.

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 73 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 $1,210 per ton on average versus $237 per ton for plastic (PET) and -$21 per ton for glass.

The data reflects an average price for recyclable materials from February 2018 – February 2020.  The implications are clear – without aluminum, very few curbside pickup programs would be financially viable.

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. In 2019, 50 billion cans – more than $810 million worth of aluminum – ended up in a landfill, a major loss to the economy and the environment. Making a can from recycled aluminum saves more than 90 percent of the energy required to make a new can.

The energy saved by recycling 100 percent of aluminum cans could power 4.1 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. Increasing aluminum can recycling rates is a concrete step that can save resources and energy, grow the economy and help shore up recycling systems of all types in the United States.

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.
