A report by the World Steel Association reveals that the global iron ore production reached 2.4 billion tonnes in 2020, with the mining process contributing to habitat destruction, air and water pollution, and greenhouse gas emissions.

In contrast, disposable cups are typically made from virgin plastic derived from fossil fuels or paper sourced from trees. The United Nations Environment Programme (UNEP) states that the extraction and processing of these raw materials also come with significant environmental challenges, such as deforestation and the depletion of non-renewable resources.

Did you know?

• Producing one ton of stainless steel requires around 1.5 tons of iron ore and 0.5 tons of coal.
• The production of a single plastic cup emits approximately 0.05 kg of CO2 equivalent.

Manufacturing Processes: Energy Consumption and Emissions

Once the raw materials are obtained, they undergo various manufacturing processes to transform into the final product. For stainless steel tumblers, this involves energy-intensive processes like smelting, casting, and forming. The International Stainless Steel Forum reports that the global stainless steel production reached 50.9 million metric tons in 2020, with these processes contributing to greenhouse gas emissions and other pollutants.

Plastic and paper cup manufacturing also require significant energy inputs and can generate waste and emissions. A study by the University of Cambridge found that the production of a single stainless steel tumbler emits approximately 1.4 kg of CO2 equivalent, while a disposable plastic cup emits around 0.05 kg of CO2 equivalent. However, the long lifespan of stainless steel tumblers can offset this initial environmental impact.

Transportation Footprint: From Factory to Consumer

Once manufactured, the tumblers and cups must be transported to retailers and ultimately to consumers. The mode of transportation and distance traveled can significantly impact the overall environmental footprint. A 2018 study by the European Environment Agency reveals that shipping by sea is generally more eco-friendly than air or road transport due to lower emissions per unit transported.

The study also highlights that transportation accounts for about 6% of the total greenhouse gas emissions associated with a stainless steel tumbler’s life cycle. Optimizing logistics and choosing efficient transportation methods can help minimize this impact.

End-of-Life: Recyclability and Biodegradability

What happens to our drinkware when we’re done with it? Stainless steel tumblers are highly recyclable, with recycling rates of up to 90% according to the International Stainless Steel Forum.
