Chicken Waste Power: Farmer Turns Poop into Electricity
23 Oct
Summary
- Farmer plans to process 35,000 tonnes of chicken litter annually.
- System could generate electricity to power approximately 1,200 homes.
- Waste is transformed into electricity, fertiliser, and natural food colouring.
An Australian poultry farmer is developing an innovative system to transform chicken waste into electricity, fertiliser, and natural food colouring. The proposed facility aims to process 35,000 tonnes of litter annually, potentially generating enough electricity to power approximately 1,200 homes. This method combines anaerobic digestion with nutrient recovery and algae cultivation.
The process uses microorganisms to break down organic material in an oxygen-free environment, producing biogas rich in methane. This biogas can be captured and used to generate electricity, supplying the farm's needs with surplus power exported to the grid. The residue from digestion, known as digestate, contains essential nutrients.
Nutrients recovered from the waste are used to cultivate spirulina algae, which can be processed to produce natural blue food colouring. This adds a unique revenue stream alongside electricity and fertiliser production. The digestate itself can be repurposed as fertiliser, returning valuable material to agriculture.
The project, located in Victoria's Gippsland region, has secured an environmental development licence. While a licensed facility handles 15,000 tonnes annually with a 1.1-megawatt unit, the farmer is exploring a larger capacity expansion, highlighting the project's evolving scale and ambition for sustainable waste management.
