Breakthrough Technology Reduces Methane Emissions in Dairy Farming

Strategic Insights

— 1 min read

Renowned scientists from Lincoln University have developed an innovative effluent treatment system in partnership with Ravensdown, significantly reducing methane emissions from farm dairy effluent ponds. The new technology, branded EcoPond, achieves a 99% reduction in methane emissions, as well as slashing E.coli, ammonia emissions, and phosphate leaching losses by up to 90%. This breakthrough has far-reaching implications for the dairy farming sector and global climate change mitigation efforts, particularly in the face of the recent COP26 climate summit's methane reduction pledges.

Key Takeaways:

  • The EcoPond system reduces methane emissions from farm dairy effluent ponds by up to 99%, making it a gamechanger for dairy farmers.
  • The system utilizes iron sulphate, a safe additive used in drinking water treatment, to achieve its highly significant reductions in methane emissions.
  • The EcoPond system can be easily retrofitted into a farmer's existing effluent system, making it a convenient and efficient solution.
  • The technology has been proven effective in the Lincoln University Research Dairy Farm, resulting in a 4 to 5% reduction in an average dairy farm's overall methane emissions.
  • The EcoPond system also slashes the amount of E.coli in the treated effluent, reduces ammonia emissions, mitigates odour, and cuts phosphate leaching losses from effluent areas into waterways by up to 90%.
  • New Zealand, a participant in the COP26 climate summit, has pledged to reduce methane emissions by 30% over the next decade.
  • Professors Cameron and Hong Di hope that the greenhouse gas mitigation delivered by EcoPond will be a significant step towards reducing methane emissions and mitigating climate change.

Statistics:

  • Up to 99% reduction in methane emissions from farm dairy effluent ponds.
  • Up to 90% reduction in E.coli emissions.
  • Up to 90% reduction in ammonia emissions.
  • Up to 90% reduction in phosphate leaching losses.
  • 4 to 5% reduction in an average dairy farm's overall methane emissions.
  • 30% reduction in methane emissions pledged by New Zealand over the next decade.
