Fonterra develops plant-based packaging

From sugar cane in Brazil to a sustainable, plant-based, plastic milk container now on sale in NZ supermarkets.

This is just one of many innovations being developed by Fonterra, as the dairy co-op moves to make all its packaging recyclable, reusable or compostable by 2025. 

Recently, the company invited media to see, first-hand, some of its innovations in packaging and product development being undertaken at its Technical Centre at Palmerston North.

Packaging is a big issue, with strong community pressure for companies such as Fonterra to improve the sustainability of its packaging materials. The company says packaging is a complex global issue and the materials used are very complex, but it’s doing its bit to better understand what recyclable actually means in all its markets.

Emily Thomas, who is Fonterra’s sustainable packaging lead, says not only must new packaging be recyclable. It also has to meet rigid food safety requirements and deal with the natural complexities that happen with products such as cheese, which require quite specific conditions to maintain its shelf life.

“If you think about something like cheese, we are going to wrap up a 20kg block of cheese in plastic, put it in a box and then allow it to mature for some months or even years,” Thomas explains.

“There are cheeses that continue to ferment, if you think of Swiss cheese there are holes in it and they are developed by gas during that maturation process. If we don’t let some of that gas out of the bag it’s going to explode, but we don’t want a bag with holes in it either because we don’t want the water to drain out because the cheese will dry out.”

Thomas says Fonterra is working with packaging suppliers both in NZ and overseas to ensure that it has the best options available. She says new materials are being developed such as a recyclable film to wrap Mozzarella cheese that Fonterra now produces.

She says new recyclable sachets for milk powder are now being trialled and if this proves successful it will add to the array of sustainable packaging being used by Fonterra.

On the home front, a new Anchor brand, 2 litre milk bottle was released on the market towards the end of last year. In one sense, it’s a polyethylene bottle just like the standard bottle, but it’s different in that it is made from ethanol, which is made from sugar cane grown in Brazil.

The bottle looks slightly different, in that the plastic appears to be thinner and lighter. From the consumer’s point of view, it is slightly more expensive because the resin is more expensive to make. Like the old bottle, it is also recyclable, Thomas says.

“The polyethylene, instead of being sourced from the petrochemical industry, has been manufactured from sustainably produced sugar cane,” she explains. “You can make ethanol from sugar cane – that’s been done for years and the ethanol can be turned into polyethylene. But the big advantage is that its carbon footprint is very low.”

Thomas says having a milk bottle with a low carbon footprint gives consumers an option and it’s a matter of choice. But Fonterra has no plans to make all its milk containers from ethanol because that would put up the overall price of milk and potentially reduce market share in a competitive market.

Fonterra says the introduction of the plant based milk bottle is just one example of the company’s sustainable packaging commitment in action.
