Dutch poultry processing company Esbro is the first to install “Aeco-FAT” technology. With that, they turn fat from wastewater produced in their plant into useful biofuel.
Dissolved air flotation (DAF) is a technique to treat industrial wastewater with high oil and grease content. It enables removal of 50-80% without using chemicals.
Fat is part of the dry matter constituent of the sludge. It is often considered to be waste, however it has high potential as an economically valuable biofuel resource.
This “Aeco-FAT” technology was developed by Nijhuis industries, and applied in poultry processing for the first time by Esbro. It is a total sludge management solution including a dissolved air flotation unit, followed by a disconnector and separation into water, liquid fat, and a solid fraction.
In the Esbro processing plant, the fat fraction is separated in such a way that it can be easily burned. Thus, Esbro is using it as energy source in its processing plant.
Apart from reduced energy expenses, less chemicals are needed for wastewater treatment . Moreover, there is less residue, resulting in less waste disposal.
By using this modern technology, Esbro is contributing to a circular economy. This is totally in line with their aim to produce in a sustainable way as they feel a strong responsibility for the environment.
