Project Alpakka, with Norway based aluminium company 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 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.
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.
