Renewable energy (Biogas)

The majority of emissions from conventional piggeries comes from the effluent (sewage) pond system on farms.
This gives us a fantastic opportunity to transform waste into energy through biogas. By capturing the biogas from these ponds, we can potentially eliminate the need to buy electricity from the grid.
Biogas is a renewable fuel. It’s produced by turning waste into energy.
Up to 80% of farm emissions can be reduced by using biogas.
Energy from biogas is produced by capturing, cleaning and burning the methane that is released by effluent (manure) breaking down.
On a piggery, biogas can be captured by:
Covering a primary effluent pond with an impermeable membrane or,
Pumping it into a specially engineered system (tanks). It can then be used to reduced farm emissions by offsetting gas use and generating electricity
If you run your farm on biogas you can:
Contribute to reducing GHG emissions
Reduce or eliminate the need for coal fired electricity
Register and quality for the Emissions Reduction Fund project. This can help you with the payback period of biogas systems.
Note: if you wish to generate Australian Carbon Credit Units (ACCUs) from your project, you’ll need to register before you sign any contracts or start the process of designing your system.
More and more Aussie pig producers are becoming interested in biogas technology. To address this, we’ve developed a risk-based Code of Practice.
The Code can help you understand:
A risk-based approach to biogas plants
Covered anaerobic digestion systems
Operation and safety
Some key biogas facts:
A 500 sow, farrow-to-finish piggery has the potential to produce enough energy to power:
3.1 million 100watt globes for one hour
Electricity to run 62 houses for one year
If combusted and destroyed, this would eliminate the equivalent of the fossil fuel GHG emissions from 458 Toyota Corollas travelling 20,000km/per year burning 7L/100km.
