Carbon footprint of New Zealand dairy farms using circular feed supplements

To improve circularity on dairy farms, you can either improve efficiency, reduce nutrient losses, green house gas emissions and waste, or use inputs that are sustainable, requiring few non-renewable resources and having a low environmental footprint.

Our work explores the use of waste streams from other industries to replace current less sustainable purchased feeds on a dairy farm in New Zealand, and the impact of this on the carbon footprint of a dairy farm from cradle to farm gate.
