The Christchurch works site has completed its latest multi-million dollar improvements so that it can carry out its essential work of nutrient supply in a safe, efficient and environmentally considerate way.   The superphosphate manufacturing facility, which celebrates its 100th anniversary next year,  completed its new stormwater solution as well as its new intake system to take delivery of nutrients sourced from around the globe.

As the Lyttelton Port’s largest customer, the Christchurch site brings in about 240,000 tonnes of nutrients every year and the flow of trucks at peak times needs to be well managed according to Peter Hay, Works Manager.  “The new intake system delivers increased throughput and safety while the new automatic high-speed doors, improved product transfer point design and baffle system enable better dust control,” said Peter.    

The new stormwater solution is made up of three dedicated basins as part of a $6m investment in improving how water is stored. ‘First flush’ water from across the site that occurs during rain events is stored before the water is slowly pumped to the Christchurch trade waste system.  Process and stormwater from the acid plant continues to be reused in the manufacturing process. “We have still have work to do, but our consultants are out advising farmers on mitigating nutrient impacts on freshwater so ensuring we’re consistently trying to improve our own footprint is all part of walking the talk,” added Peter.

Fifty employees work in the Christchurch works which serves about 3,000 farmers and growers in the Canterbury region. These owners of the co-operative depend on an assured supply of nutrients to boost soil fertility and create food for humans and livestock. Many of those farmer-owners who depend on their Christchurch store staying open are from the arable and sheep & beef sectors as well as dairy.
