Benefits of aluminum vs steel: from environmental impacts to meeting consumer needs

Transparency in products remains important to consumers. They want to know where the everyday products they purchase are coming from, what they are made of and if they fit their shopping preferences. According to a study from Nielsen and Label Insight, 39% of shoppers would be willing to switch brands to start using products with more transparent labels, meaning they want to know more about the product sourcing information.

One of the biggest forms of transparency that consumers want is a look inside a company’s sustainability efforts. Previously, packaging companies relied on retailers and brands to deliver messaging about waste, recycling and circularity. But now, under pressure from NGOs and other groups to reduce waste, the packaging industry is having to address consumers directly. Because of this, many companies are looking for alternative materials for packaging options.

Making small changes in the materials that companies use can result in large sustainability impacts. One material that is being phased away is steel. Many packaging companies have found a more durable and sustainable alternative that is just as cost-efficient.


Making the switch to aluminum packaging

Aluminum has proven to be a trending new alternative to steel, especially in products such as electronics, building parts and even jar lids. Aluminum is at the top of the recycling chain and can easily be recycled without damaging its durability and quality. Because of this, brands are starting to make the switch to aluminum from other metal packaging that has traditionally been used. In fact, according to The Aluminum Association, more than two-thirds of all aluminum that has been produced in the world is still in use today.


The sustainability benefits of aluminum

Unlike steel, the process of recycling aluminum requires less energy and time. The Aluminum Association also found that “Aluminum is 100 percent recyclable and retains its properties indefinitely. Aluminum is one of the only materials in the consumer disposal stream that more than pays for the cost of its own collection.”

When using materials like steel in packaging, the metals tend to corrode, causing packaging companies to spend additional money on coatings. Plastisol is a liquid that can be heated to form a flexible and rubber-like material that is widely used for a number of packaging needs, including sealing lids to jars. If any metal exposure is present when producing a product like jar lids, it can form corrosion from curing the plastisol to the coating. Most jar lid manufacturers will put a coating over the metal to prevent corrosion do to the acidity of the product being placed in the jar.

Although it sounds like an easy fix, plastisol and other coatings can add up in cost, slow production lines exponentially, and create even worse impacts on the environment.


How does aluminum hold up against steel?

For companies who are on the fence about making the switch to aluminum, the benefits of this material go way beyond sustainability. The cost of recycled aluminum is far less expensive than that of steel, allowing manufacturers to purchase materials that save them money without sacrificing quality.

As far as corrosion, aluminum actually holds up better than steel. The material does not rust easily and does not need additional coatings to maintain its quality. In contrast, steel tends to corrode and rust at a much faster rate. Because of this, manufacturers sacrifice the quality of their goods when it comes to shipping products to different environments. Numerous factors such as air quality or abrasive shipping methods can test the durability of steel and potentially cost manufacturers to replace goods.

Additionally, with the rise of e-commerce sales stemming from COVID-19, more and more consumers are opting to shop online. This means that manufacturers should prepare to see an increase in shipments, especially as we approach the busy holiday season for retailers. Because of this, many packaging companies are considering aluminum due to its light weight, which allows manufacturers to maximize the amount of product that can be shipped at once. Aluminum is shockingly one-third of the weight of steel, making it an easy choice for manufacturers to consider.


Meeting consumer needs

It’s crucial packaging companies and manufacturers are listening to consumer needs and taking them into account when it comes to producing a product. Practicing material transparency and emphasizing sustainability efforts will both put companies in a better position when it comes to meeting consumer needs and matching their shopping preferences.

In a study by IBM, it showed that 57% of consumers wanted to change their shopping habits to help reduce negative environmental impacts. The switch to sustainable materials—like aluminum—is only projected to increase as consumers continue to shop with sustainability in mind.

Overall, the benefits of aluminum outweigh those of steel – everything from sustainability to durability, transportation and meeting consumer needs.

Kia ora! Sustainability is at the core of my soul ever since I was a kid. I always strive to finish the food on my plate and live as a minimalist. I love to cut down on waste in order to live sustainably and harmoniously with our planet. This brings me to my passion as a Food Scientist to integrate new technologies into innovative and creative solutions to meet customer demands and market trends and to optimize products and processes for quality, savings and sustainability. To these goals, I have published a Journal on my work on sustainable packaging and patented a new Antimicrobial wash. Nothing is more satisfying than working hard and smart at the workplace and playing hard outside of working hours. I enjoy rejuvenating myself through spending quality time with my two adorable kids and my awesome soul mate and getting close to nature when possible, be it gardening, tramping or going to the beach. I also love to learn about our magnificent universe and how sustainability is working in the grand scheme of things. I strongly believe that Work, Life & Balance is the key to a healthy state of mind, both physically and mentally. I look forward to making a positive difference wherever and whenever I can. Through this Blog, I hope to catalog recent Food Trends and Food Technologies that I come across so that anyone who is interested can have access to it (articles and resources). Please use these resources at your discretion. On top of that, I would also like to share related news and technologies of the future that would help mankind advance towards a Type 1 Civilization. Please feel free to contact me if you would like to share and contribute to the “Resources“. I would like to thank you in advance for dropping by. I sincerely hope that you can benefit from the recent Food Trends and Food Technologies I catalogued. Kind regards | Ngā mihi RenSun Lee
