Alternate methods for phosphate sludge disposal

We generate phosphate sludge to the tune of approx. 3500 kgs in a month. As we are unaware of commercially viable alternatives of disposal, we dump them in a landfill conforming to ISO 14000 standards. Do suggest alternates where it can be recycled in a commercially viable manner. Which industries can use sludge as an input?

I would welcome suggestions in this regard.

You can compost or vermi compost your sludge and use the recycled waste for plants as manure. I am also student of environmental sciences working on the project to see how far it is efficient in composting.
