Project overview


Undertake a study for a biomass processing plant for the management of wastewater sludge and organic solid waste. 


The Project is looking to adopt innovation in the way wastewater and solid wastes are managed, aiming to (i) improve the removal of nitrogen and phosphorus, aiming to maintain an effective nutrient balance on irrigation of crops (ii) recycle water on allowed operations and (iii) reduce overall carbon footprint.   


The Project incorporates a two-stage anaerobic digestion process as a pivotal component of its waste management strategy. This innovative approach involves a sequential and optimised breakdown of organic materials, efficiently harnessing their energy potential while minimising environmental impact. 

In the first stage, complex organic matter such as fats, proteins, and carbohydrates are subjected to anaerobic conditions. This promotes the activity of acidogenic microorganisms that metabolize these compounds into simpler molecules like volatile fatty acids, alcohols, and hydrogen. This phase generates intermediate products rich in energy and serves as a preparatory step for the subsequent stage. 

The second stage, termed the methanogenic phase, is where methane-producing archaea flourish. The products from the first stage serve as substrates for these microorganisms, which convert them into methane and carbon dioxide through a series of biochemical reactions. This biogas, predominantly composed of methane, is a valuable source of renewable energy that can be harnessed for thermal and electrical purposes. 

The two-stage AD process offers several advantages: it enhances the overall efficiency of organic matter conversion, ensuring a higher biogas yield, provides a more stable and controlled environment for specific microbial communities and contributes to waste reduction by converting organic materials into valuable resources. 


The Study will achieve the following Outcomes: 

(a) enable a decision by the Recipient to: 

  (i) proceed to fund implementation of the studied Project; or 

  (ii) proceed to a more detailed engineering study; or  

  (iii) terminate further development of the studied Project; 

(b) inform the meat processing industry of the barriers to implementation of the studied Project and potential solutions to these barriers; 

(c) accelerate uptake of similar projects across the meat processing industry; and 

(d) enable accelerated transformational improvement in industrial renewable energy and/or energy efficiency and greenhouse gas emissions compared to baseline or business as usual across meat processing facilities.
