Fonterra Edendale hub manager Keith Mason said it had worked hard and invested "significantly" to improve its environmental performance. "The quality of the air discharged from the site and this award reinforces the results we're achieving." Its work in this area reflected the importance Fonterra placed on sustainability and environmental performance, not just at its Edendale plant but right through its international supply chain. "Our business strategy is founded on the basis of being among the world's lowest-cost, most sustainable producers of dairy products," he said. "That means we're always looking at resource use and minimising any possible environmental impacts from our operations." This approach was a top priority and crucial to the industry's sustainability, Mr Mason said. "This is an area where we can't stand still and so it was great news that Fonterra Edendale received the top environmental accolade at our annual Best Site awards.
