Turning chicken poo into biofuel

At some farms in Singapore, chicken droppings are put to good use and are converted into biofuels.


SINGAPORE: Eggs are not the only cash cow for some farms in Singapore.

Chicken droppings are also being put to good use and are converted into biofuels.

At Chew’s Group's farm in Lim Chu Kang, about 700,000 chickens produce 60 tons of droppings a day.

It's building a plant, costing about S$5 million that can convert the waste.

It hopes to use this to replace the current practice of treating the fresh manure and selling it to vegetable farmers in Singapore and Malaysia as fertiliser, because the process is expensive and needs a lot of space and manpower.

The first phase of the new plant will be completed by the end of this year and can supply up to 70 per cent of energy needs.

If it succeeds, the farm hopes to scale up.

Executive chairman of Chew’s Group, Chew Chee Bin said: "We actually need to solve our chicken dung problem. Traditionally, we take 35 days to ferment the chicken dung and supply to local and Malaysia vegetable farmers. By using the biogas system, we can reduce almost 50 per cent of land use, reduce manpower use, and increase egg production.

“If we enter into the second phase, we will treat 80 tons of chicken dung, which in turn will produce almost one mega kilowatt hours, which is sufficient to supply the whole farm and supply to the power grid."
