Hydro and Partners Establish Research Project on Recyclable Food Packaging

Project Alpakka, a new collaboration between Hydro, Metallco, Infinitum, Norsk Metallgjenvinning and Kavli, along with NTNU and SINTEF, will save Norway more than 1.5 TWh of energy and several hundred thousand tonnes of CO2 each year by increasing the recyclability of food packaging.


Aluminium is widely used in food packaging, from squeezable tubes to yogurt tubs, mackerel tins and juice cartons, where it offers a unique ability to extend shelf life and reduce food waste.

The challenge is to ensure that the packaging is delivered for recycling and returns into circulation. This requires close cooperation with experts along the value chain and better communication with consumers.  

“For us as an aluminium company, it’s important to take industrial responsibility and ensure that the metal we produce returns into circulation and can become new products,” says Hans Erik Vatne, Hydro’s Head of Technology.

”We believe aluminium is the metal of the future, as it can be recycled again and again, but we must work together to develop even better solutions and raise awareness among consumers. Technology, innovation and collaboration are crucial here, so we’re pleased to gather experts from all relevant fields in this project.”

Project Alpakka, with Hydro at the forefront, includes those responsible for collection and recycling, Norsk Metallgjenvinning, Metallco and Infinitum, the food producer Kavli, as well as the Norwegian University of Science and Technology (NTNU) and the Foundation for Scientific and Industrial Research (SINTEF) that are providing research support. The project will receive NOK 15 million in support from the Research Council of Norway over three and a half years.

Aluminium reduces food waste - but more must be returned after use 

According to Kavli, which also owns Q-Meieriene, four out of five of their food product tubes are thrown into the trash rather than recycled, and this is something they want to change.  

“From a sustainability perspective, aluminium is fantastic for extending shelf life and reducing food waste. But today too much is thrown in the bin– our goal is that all the tubes we sell are returned to recycling. To achieve this, it’s important for us to communicate effectively with our customers and mark the packaging so that there is no doubt about what to do with the packaging after use,” says Annette Waage Jung, Innovation and Product Development Manager in Kavli. 

In addition, Kavli will work with its suppliers to improve the design of the tubes, to ensure 100 percent recyclability by 2025. According to Infinitum, the company behind Norway’s deposit and collection system and a supplier of aluminium cans for recycling to Hydro in Holmestrand, there is also great potential for recovering more aluminium in food packaging.  

“While there’s a lot of aluminium in buildings and cars that takes a long time to return for recycling, packaging – like drink cans – has a very short service life before it can get back into the loop. Together with Norsk Metallgjenvinning, we will therefore measure how much is returned to recycling today and work together to develop new solutions and incentives to increase the amount of packaging that is returned from consumers. To achieve this, we believe crucial elements from Infinitum’s successful bottle collection model can be utilized do develop other collection systems, such as for food packaging,” says Kjell Olav A. Maldum, CEO of Infinitum.  

NTNU and SINTEF will support the project through research, including a doctoral position.  


Project Alpakka
  • Project Alpakka is led by Hydro, and includes the partners Metallco, Kavli, Infinitum, Norsk Metallgjenvinning, SINTEF and NTNU
  • The project will work to prevent 40,000 tonnes of aluminium going to waste incineration annually, saving more than 1.5 TWh of energy and several hundred thousand tonnes of CO2
  • This will be achieved through close collaboration across the value chain, including collectors, food producers, packaging designers and metal recyclers, as well as with consumers
  • Aluminium is 100% recyclable, and recycling requires only 5% of the energy required to produce new aluminium Increasing the recycling rate of food packaging will eliminate large amounts of CO2 and show how a circular economy works in practice
  • The project is supported by The Research Council of Norway through a grant of NOK 15 million over three and a half years
