Press mud is commonly known as filter cake / press cake and is used as manure by the farmers. Press mud is the residue of the filtration of sugarcane juice. The clarification process separates the juice into a clear juice that rises to the top and goes to manufacture, and a mud that collects at the bottom.
It is combustible and also used in brick kilns for brick making. When mixed with the spent wash generated by the distilleries, the resultant product is enriched organic manure, which has the capability to improve yields in farms. The use of filter cake as a soil conditioner is common among sugar planters.
