Is Aluminum Really a Greener Packaging Option? The Truth Behind the Hype

Many companies claim aluminum is a more sustainable alternative to plastic and glass, but is that really true? Bloomberg once published an article suggesting that aluminum is greener than glass, but a deeper look into the facts reveals serious environmental and health concerns.

The Hidden Costs of Aluminum Production

Unlike what many greenwashing campaigns suggest, aluminum production is not eco-friendly. The process of extracting aluminum from bauxite mining is highly destructive to the environment.

How is aluminum made?

1️⃣ Land is stripped—Forests, trees, and vegetation are bulldozed.
2️⃣ Rocks and clay are blasted, bulldozed, and drilled to access bauxite ore.
3️⃣ Toxic chemicals are used—A hot caustic soda solution dissolves the aluminum.
4️⃣ 11 additional steps involve intensive chemical treatments, water use, and energy consumption.

Did you know?
✔️ In Ontario, 96% of glass beer bottles are recycled and reused up to 15 times.
✔️ Less than half of aluminum packaging is recycled, meaning the majority ends up in landfills.


Health Risks: Aluminum & Toxic Leaching

Aluminum is often used in food and cosmetic packaging, but few people realize that it can leach into products.

  • Aluminum exposure is linked to:
  • Alzheimer’s Disease
  • Parkinson’s Disease
  • Breast Cancer
  • Bone Disorders
  • Neurotoxicity (brain cell damage)

Why does aluminum leach?
 The human body struggles to excrete aluminum, leading to a buildup over time.

Scientific studies confirm the dangers—just Google "Impact of Aluminum on Human Health".


Aluminum Uses Hidden Plastic Liners

Many people don’t realize that aluminum packaging is lined with plastic polymers—including BPA, an endocrine-disrupting chemical known to interfere with hormones.

  • Example: Coca-Cola still uses BPA liners in their cans—this is confirmed directly on their website!
  • Most aluminum packaging requires plastic linings, meaning it isn’t as plastic-free as marketed.

Bottom Line: While aluminum may use less plastic than a full plastic container, it still relies on toxic plastic linings, negating its so-called sustainability.


Aluminum vs. Plastic & Glass: Pros & Cons

Pros of Aluminum Packaging

Less plastic (compared to full plastic containers)
Recyclable (but less than 50% actually gets recycled)
Lightweight (reduces shipping costs & emissions)
Non-breakable (safer than glass for transport)
Easier to find in North America

Cons of Aluminum Packaging

Less than half of aluminum gets recycled—most ends up in landfills.
Leaching into products—posing serious health risks.
Lined with dangerous plastic polymers—including BPA and other endocrine disruptors.
Bauxite mining has a devastating environmental impact—destroys ecosystems & communities.
Extremely high energy consumption—manufacturing aluminum uses massive amounts of electricity, water, and toxic chemicals.


Final Verdict: Is Aluminum Truly Sustainable?

While aluminum is heavily marketed as an eco-friendly alternative, the truth is far more complicated. Aluminum mining, processing, and reliance on plastic liners make it far from the "green" option it's claimed to be.

✔️ Yes, it’s lighter than glass, reducing shipping emissions
But its environmental and health impact outweigh the benefits

The most sustainable choice? Buy products with minimal packaging, reuse containers, and recycle properly.
