In a bid to replace the aluminium-based barrier, Tetra Pak is testing fibre-based layer in its cartons because aluminium contributes to carbon emissions while being not a favourite with recyclers and for being unable to sustain vegetable juice as evidenced from the 15-month-long consumer test held in Japan in 2020 by the company. From these findings, Tetra Pak has shelved its fibre-based cartons for consumer testing. According to the company, this change would not only impact the composition of packaging material but also opening, closing, and sealing technology. Tetra Pak’s long-term goal is to make its packaging as renewable, recyclable and carbon-free as possible to reduce environmental impact. 100 million dollars are invested every year towards this goal. Recently, Tetra Pak collaborated with Elvir, a subsidiary of milk processor Savencia Fromage and Diary, to manufacture their first carton cap made of certified recycled polymers. They also collaborated with EnginZyme for food waste solutions.
