Project overview


G&K O’Connor will undertaking a feasibility study to reduce energy usage at their co-located abattoir, rendering, and wastewater treatment plant in Pakenham, Victoria. 


Like many Australian industries, G&K O’Connor is a large user of grid gas and electricityWhilst the company has already actioned several immediate opportunities for improving energy efficiency and switching to renewable energy sources, this study will identify pathways for G&K O’Connor to close the loop on process energy and emissions. The integrated nature of the study enables synthesis of opportunities for renewable and energy efficient pathways in contrast to the usual piecemeal approach.        


The study will assess a range of decarbonisation pathways for the red-meat processing facility which will incorporate:   

  1. a number of energy efficiency initiatives identified through the prior energy audit; 
  2. a design review of the proposed upgrades to the rendering plant and new cool storage facility proposed for the site to optimise heat integration; 
  3. utilisation of renewable energy generation from solar photovoltaics (PV), energy storage, co-generation from biogas, demand flexibility and off-site renewable electricity; 
  4. installation of a new covered anaerobic lagoon (CAL) to treat the wastewater from the facility using generated biogas for boiler fuel to substitute natural gas; and 
  5. evaluation of the electrical infrastructure on site and its suitability for renewable energy integration. 


The study will achieve the following outcomes: 

  1. Enable a decision to proceed to a more detailed engineering study. 
  2. Inform industry of the barriers to implementation of decarbonisation pathways for the red-meat processing industry and potential solutions to these barriers. 
  3. Inform the roll out of decarbonisation pathways in similar industrial processing facilities. 
  4. Enable accelerated transformational improvement in industrial renewable energy and/or energy efficiency and greenhouse gas emissions compared to baseline or business as usual. 


Additional Impact

Australian Meat Processor Corporation (AMPC) is supporting the study given its unique integrated approach to optimising energy efficient heat recovery, switching to cleaner fuels via electrification, and renewable energy sources from solar PV and biogas.
