Fonterra takes a waste product (Proliq) from milk processing, and creates a nutritious feed product for dairy cows. The goal is to have 100% reuse of the waste product, and none treated as wastewater or discharged to land.
The creation of Proliq is part of Fonterra’s strategy to minimise the environmental impact of dairy manufacturing. Proliq is a protein, energy and mineral rich by-product from the removal of lactose from whey. It is a valuable supplemental feed product.
Four of Fonterra’s manufacturing sites create this waste product, and the cooperative has established a market around each, to be able to effectively achieve zero waste. In building a new mozzarella plant at the Clandeboye manufacturing site, Fonterra has simultaneously created a market for over 20 million litres of the by-product. All of it was sold in 2019.
Fonterra sells 87 million litres of Proliq to farmers. This diverts 350,000 kg of nitrogen and 385,000 kg of phosphorus from waste treatment systems.
