Lincoln University and Ravensdown have launched a collaborative project aimed at reducing methane emissions from dairy farm effluent ponds. Effluent ponds are a significant source of methane in the dairy sector. The project focuses on refining the EcoPond effluent treatment system, which uses ferric sulphate to inhibit methane-producing microbes. Early research shows potential for reducing methane emissions by over 90%. The Ministry for Primary Industries is investing $2.9 million through the Centre for Climate Action on Agricultural Emissions to support this initiative. The project will expand nationally to assess EcoPond's effectiveness across different regions and farm systems. Farmers at Lincoln University's Dairy Farm report promising results, noting cleaner ponds and reduced odors. This initiative not only targets methane reduction but also addresses freshwater contamination issues. Future steps include further testing in various seasons to assess year-round benefits, aiming to develop a practical, scalable solution for dairy farmers.
