Metal cans, including aluminum and steel, provide a proven sustainable alternative to plastic packaging. Aluminum beverage cans, for instance, are the most widely recycled packaging in the world. In the US, we recycle around 56 percent of aluminum cans – the equivalent of 5 million every hour - and 71 percent of our steel cans(1).

Brazil, meanwhile, holds the record for aluminum with a 98.4 percent recycling rate(2). With EU following strong with a 76.1 percent recycling rate reported by European Aluminum and Metal Packaging Europe industry associations.

How can we collectively contribute towards increasing those recycling levels and the circular economy?

How can we work together to ensure every can counts and contribute towards a recycling revolution?

The circularity of metal packaging

Research from the Can Manufacturers Institute (CMI) shows that metal cans are the circular, sustainable packaging choice. Cans offer high levels of recycling and economic value to help companies meet their sustainability goals. Both aluminum and steel are infinitely recyclable(3).

Aluminum, for instance, is lightweight and strong, containing an estimated 73 percent recycled content (triple that of a glass or plastic bottle according to the Aluminum Association). Making a beverage can from recycled aluminum reduces energy and carbon emissions by over 90 percent compared to using new aluminum. In contrast, plastic degrades in reprocessing and can rarely be recycled more than once.

Aluminum cans contain 73 percent recycled content, almost triple that of glass and plastic bottles according to the Aluminum Association.

Making every can count: Sustainable initiatives

Metal offers a high economic value in the circular economy, offering a revenue source of $100 per ton for steel and around $1,000 per ton for aluminum. If the can industry achieves its goal of recycling every aluminum can, it would add $800 million of economic value in the circular economy. Initiatives are in place to increase the rate of aluminum can recycling, including:

Ball’s Aluminum CupTM
Launching its own recycling revolution, Ball’s innovative Aluminum CupTM is specifically designed to reduce the impact of single use plastic cups with a more sustainable alternative. Once recycled, the aluminum contained in the cup can be brought back to market as a new can or a cup within just 60 days.

Grants to MRFs (Material Recovery Facilities)
From 2021 CMI, in collaboration with Crown Holdings and Ardagh Group, will be offering grants to MRFs (material recovery facilities) to promote recycling and sustainability packaging solutions(4).

Funding is intended to enable manufacturers of aluminum beverage cans to invest in aluminum can capture equipment. This initiative will help to reduce the numbers of missorted cans (currently around 25 percent). The capturing of missorted cans is good news for the environment, in reducing carbon emissions from higher levels of recycling, and for MRFs, increasing revenue.

The grants are expected to encourage more MRFs to invest in additional aluminum can capture equipment.
