Graphic: An abundance of aluminum scrap to spur U.S. recyclers


The growing use of aluminum by transport and packaging firms in the United States has created an abundance of scrap and is encouraging recyclers to expand capacity in what industry analysts see as the start of a new trend. 

Those already expanding include Novelis, one of the world’s largest producers of rolled aluminum products, which last month announced plans to invest $36 million to boost and upgrade recycling capacity at its Greensboro facility in the United States, to be completed during the second half of 2021. 

Canada-based Matalco is also planning a new $80 million aluminum recycling facility in Wisconsin while JW Aluminium is expanding its facility in Goose Creek in South Carolina at a cost of $255 million.

“Scrap buyers are struggling to take more, investment is needed,” said Citi analyst Oliver Nugent. “If you think the tariffs on primary aluminum are here to stay then it makes sense to think about alternatives like scrap.” 

The United States has a 10% levy on imports of primary aluminum, but not on scrap, where prices have plummeted. 

A proxy for auto scrap is the LME’s aluminum alloy contract CMNA3 which fell by more than half to $1,000 a tonne in October from above $2,000 in April 2018. It is now at $1,230.

“Scrap prices are heavily discounted because availability has outpaced capacity and because tariffs exempt scrap,” said Jorge Vasquez, founder of consultancy Harbor Aluminium. 

Harbor estimates beverage can scrap prices at nearly $900 a tonne below the London Metal Exchange’s benchmark primary aluminum CMAL3 at around $1,760 a tonne. 

It also reckons the United States generated 5.9 million tonnes of scrap aluminum last year, up about 20% since 2016. Of that about 5 million tonnes was recycled domestically, while the rest was exported. 

Valued for its lightness and anti-corrosive properties, demand for aluminum from U.S. drinks firms is expected to rise over coming years as they come under pressure to cut plastic pollution. 

In autos, the advent of electric vehicles powered by batteries and the need to reduce the weight of the car are expected to see aluminum use increase.

Data from the Aluminium Association shows aluminum use in passenger cars and light trucks climbed 23% to 6,080 million lbs between 2007 and 2017. Overall, aluminum use in transport rose nearly 20% to 9,625 million lbs in the same period. 

“To truly benefit from the circularity of aluminum requires improvements in collection, sorting and processing methods of post-consumer scrap,” said Wood Mackenzie analyst Kamil Wlazly. 

“Producing aluminum uses a lot of energy, but it can be recycled infinitely. Aluminium scrap is the future.” 

Electricity can account for between 30% and 50% of the costs of producing aluminum, depending on whether it is generated using coal, gas or hydro power. Energy costs of recycling aluminum are typically about 5% of producing primary metal. 

Total aluminum consumption in the United States this year is estimated at more than 10 million tonnes, nearly 15% of the global total at 67 million tonnes.
