Nestlé Nespresso has entered a memorandum of understanding (MoU) with mining and metals company Rio Tinto to produce its coffee capsules using responsibly sourced aluminium.

As part of the agreement, both companies will work collaboratively with Nespresso’s capsule manufacturers to source 100% sustainable aluminium by 2020.

Rio Tinto aluminium CEO Alf Barrios said: “This as an important step towards the use of responsibly sourced aluminium across manufacturing industries, which Rio Tinto is the first to supply.

“We expect the demand from consumers for sustainable products to continue growing and Nespresso drinkers can have confidence the aluminium we supply for their capsules meets the highest international standards.”

According to the company, the use of Aluminium Stewardship Initiative (ASI) certified aluminium promotes the protection of biodiversity, water management and low-carbon emissions during the production of aluminium.

“We have made responsibly sourced aluminium a reality, and the ASI traceability mechanism will enable us to meet our commitment to customers to reduce the impact of their consumption.”

Rio Tinto is the first mining and metals company to be granted certifications by the ASI.

Nespresso chief executive officer Jean-Marc Duvoisin said: “Nespresso is proud to have been a driving force in creating and implementing the ASI.

“Together, we have made responsibly sourced aluminium a reality, and the ASI traceability mechanism will enable us to meet our commitment to customers to reduce the impact of their consumption. This is a positive step towards creating a more sustainable and environmentally friendly future.”

Nespresso is headquartered in Lausanne, Switzerland, and currently operates the business in 76 countries with 13,500 employees.
