Limed Biosolids

Looking for any info from users that have tried making Class A biosolids with lime addition, specifically any problems with finding some place or someone to accept the material. The new plant mods have a proposed Bioset process using lime and sulfamic acid to make class A biosolids but have heard that it is difficult to get rid of due to high pH, clumping, etc. The high pH would be an issue here for residential or turf farming as summer season grass likes a lower pH.

 

Any thoughts?

 

Thanks!

The plants I know of that use lime on their biosolids have then composted the material.  I used it on my lawn and the grass grew all summer and was a nice dark green color.  I never had to lime my lawn either.  Clumps only stayed in the final compost during the cold weather months.  That is the extent of my knowledge in this area.

Lime stabilized sludge has been land applied in Vermont.

I suggest you contact the VT Agency of Environmental Conservation in Waterbury VT for their experience.

Concord NH also land applies lime stabilized sludge.
