As New Zealand milk production stretches processing facilities to the limit, very large quantities of buttermilk have been dumped by Fonterra, the country’s biggest dairy co-op.
This lake of buttermilk (pictured below) formed at Atiamuri in Waikato, after the by-product of butter making was hauled from Fonterra’s processing plants in Waikato and Bay of Plenty.
In addition, at least two tankers a day are discharging dairy by-product into the sea.
The buttermilk lake has since been drained and spread on farmland, and a Waikato Regional Council investigation was launched into the legality of the dumping. Meanwhile, the council has allowed Fonter ra to dispose of surplus milk products elsewhere in the region.
Fonterra has been unable to cope with milk volumes in the North Island and has been dumping low value milk by-products.
