Aluminum vs. Glass: Which is the Better Alternative to Single-Use Plastics?

March 28, 2023

As consumers become increasingly aware of the negative environmental impact of single-use plastics, many are seeking alternative packaging options for their daily necessities, including bottled water. Two popular alternatives are glass and aluminum containers, both of which have their unique advantages and disadvantages. However, when it comes to carbon footprint, a recent study by McKinsey & Company found that aluminum has a lower carbon footprint than glass.

Does glass or aluminum have a lower carbon footprint? 

Carbon footprint is the total amount of greenhouse gasses emitted into the atmosphere, such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), expressed in equivalent tons of CO2. The manufacturing process of packaging materials, such as glass and aluminum, is responsible for a significant portion of their carbon footprint.

According to the McKinsey study, the manufacturing process of aluminum containers emits 31% less greenhouse gasses than that of glass containers. This is due to the fact that aluminum can be recycled infinitely without losing its quality, while glass can only be recycled a limited number of times before its quality deteriorates. As a result, the production of aluminum containers requires less energy and emits fewer greenhouse gasses than glass.

Other advantages of aluminum over glass water bottles

In addition to having a lower carbon footprint, aluminum containers also have other advantages over glass containers. For example, aluminum is lighter and more durable than glass, making it easier and safer to transport. This is especially important when it comes to shipping bottled water, as the transportation of heavy and fragile glass containers can result in a significant amount of waste due to breakage.

Another advantage of aluminum containers is that they can be resealed, which is not possible with glass containers. This makes them a more convenient option for consumers who prefer to drink their bottled water over an extended period.

While glass containers may have some advantages over aluminum containers, such as being more aesthetically pleasing and having a longer shelf life, the lower carbon footprint and other advantages of aluminum make it a better alternative to single-use plastics than glass.

Aluminum water bottles can help businesses improve their sustainability practices 

Businesses and organizations that are looking to promote their sustainability and eco-friendly approach to doing business can benefit from using custom aluminum bottled water as a promotional product. Not only does it align with their values, but it also provides a practical and environmentally-friendly product that customers can use on a daily basis.

In conclusion, while both glass and aluminum containers have their pros and cons, the lower carbon footprint and other advantages of aluminum make it a better alternative to single-use plastics than glass. As consumers and businesses continue to prioritize sustainability, the use of aluminum containers for daily necessities such as bottled water will likely continue to grow.
