38 | DAIRY INDUSTRY Oceania Dairy Sustainability drives new projects T Richard Loader S ustainability and environmental benefits were major drivers in Oceania’s decision to undertake two parallel projects at its hi-tech Glenavy dairy processing plant—one designed to recover chemicals, the other to reduce water intake. Chemicals used in the cleaning process at the plant, normally discharged into the plant’s wastewater treatment plant, will be recovered and reused, while water content extracted from raw milk will be cleansed and reused, saving up to one million litres of bore water a day. While technology for the chemical recovery is hoped to be commissioned and operational during the months of December 2020/January 2021, Oceania plans to opera- tionalise water reduction by winter 2021, in line with the dairy off-season. Oceania’s acting General Manager Logan Hanifin says Oceania had been investigating chemical recovery for several years, scoping the project and determining how it would work in operation. “We use chemicals as part of our CIP solu- tion for cleaning internal production contact surfaces to ensure the highest levels of hy- giene are maintained,’’ Logan says. “Currently, the CIP solution and associated cleaning chemicals go into our wastewater treatment system. “The project will interrupt this process, capturing the chemicals before they enter the system. A nano-filtration membrane plant will remove unwanted particles from the chemi- cals which are then rebuilt by adding addition- al cleaning agents and re-used.” With approved scope, design and budget, the project started in earnest January this year with the membrane plant on its way from Europe, silos being built in New Zealand and earthworks starting mid-September.
