A proposed aluminium recycling plant in Benson, USA, has stirred deep concerns among local residents, who fear the facility might lead to environmental harm, noise pollution, and water overuse — if not immediately, then in the long run. While the anxieties are understandable, especially given the plant’s location near residential areas, experts suggest these concerns might be rooted more in misinformation than in facts.
The plant, led by Aluminum Dynamics, aims to recycle used beverage cans, which is symbolically an initiative to benefit the environment.“Aluminium is 100 percent recyclable. It’s infinitely recyclable, and we want to take advantage of that and keep these cans out of our landfills,” said Glenn Pushis, President of Aluminum Dynamics, in a statement addressing public fears.
And the numbers speak for themselves. Producing one tonne of primary aluminium emits up to 16 tonnes of carbon dioxide. In contrast, aluminium made from pre-consumer scrap releases only 0.5 tonnes of CO2 equivalent, and from post-consumer scrap, about 0.6 tonnes. That’s a 95 per cent reduction in energy usage and significantly fewer emissions.
Water use is another worry, but the facts again point to a smaller impact. According to the US Geological Survey, making a pound of primary aluminium consumes between 1.24 and 36.33 gallons of water, largely due to high heat processes in smelters and cooling systems. Recycling plants, which skip these intensive stages, consume far less.
Noise pollution is a valid concern for any industrial setup, but aluminium recycling facilities are quieter compared to full-scale smelters. A study by PubMed Central shows that smelters can produce community noise levels of 44–48 dB(A), with internal areas reaching up to 100 dB(A) due to heavy machinery like pneumatic breakers and furnaces. Recycling plants, lacking these high-decibel operations, are typically quieter.
Air pollution is also significantly lower in recycling operations. Unlike smelters that use Fume Treatment Plants (FTPs) and coal-based power plants, emitting hazardous gases like hydrogen fluoride (HF), sulfur dioxide (SO₂), and nitrogen oxides (NOx), recycling centres have a far smaller environmental footprint.
Beyond the environmental angle, the plant promises potential economic benefits. Once operational, it is expected to generate local employment, offering a boost to Benson’s economy.
Still, construction cannot begin until final approvals are in place. While residents remain cautious, this situation underscores the need for greater awareness around aluminium recycling, a process when done responsibly, can deliver sustainability without compromising community well-being.
