PigGas was used in a National Extension Project funded by:  

  • Ian Kruger Consulting  

  • the Australian Government  

  • Australian Pork Limited  

 

Baseline greenhouse gas emissions and emissions intensities were calculated on 55 piggeries. This represents about 24% of Australia’s pork production.  

 

Key highlights from the PigGas studies include: 

  • Reducing feed wastage or increasing feeding efficiency by 5%, resulted in about a 10% reduction in greenhouse gas emissions. 

  • Modifying existing waste treatment and reuse systems could result in 15-25% emissions reductions.  

  • Housing pigs in deep litter pig sheds resulted in about 40% lower emissions compared with housing in conventional flushed sheds.
