Aluminium is included in aseptic cartons because it prevents oxidation and light damage, keeping perishable food safe without refrigeration and preservatives for months.
On the inside of our aseptic cartons, a layer of aluminium eight times thinner than a human hair provides vital protection from oxygen and light, keeping perishable food safe without refrigeration and preservatives for months, which saves significant energy and carbon footprint through storage and distribution of the food products.
Although this layer is minute, it is also responsible for about a third of the climate impact of our base materials. In 2018, we set a tougher carbon dioxide emissions target for our aluminium foil suppliers and are continually innovating to reduce how much we use, while investigating alternative barrier materials.
Aluminium is included in aseptic cartons because it prevents oxidation and light damage. However, its production can be associated with environmental and social issues, ranging from land use and hazardous by-products; to working conditions, health and safety. Furthermore, because aluminium is traded in an open market, it can be difficult to trace back to the original source. Addressing these challenges is complex and requires continuous research and innovation, as well as working with multiple stakeholders.
As a founding member of the Aluminium Stewardship Initiative (ASI), we aim to address sustainability topics related to aluminium at an industry level. Along with Rio Tinto Aluminium, BMW, Nespresso, WWF and the International Union for the Conservation of Nature, we are working to establish a global standard that raises the bar for aluminium production, environmentally and socially.
In December 2017, the ASI released version two of its Performance Standard, and Tetra Pak became certified to the ASI's Production Standard in November last year. We are delighted to be among the first group of aluminium producers, transformers and industrial users to demonstrate sustainable sourcing of this material.
In parallel, all but one of our aluminium foil suppliers are becoming ASI members. This requires them to achieve certification standards within two years and demonstrates their commitment to socially and environmentally sustainable future for aluminium.
The Aluminium Stewardship Initiative (ASI) has announced Tetra Pak as the sixth company, and third end user of aluminium to become ASI Certified, less than a year after the certification programme was launched.
