Biosolids often pose significant problems for municipalities. This presentation discusses the benefits that granulating biosolids for use as a soil amendment or fertilizer product offers.

2. Biosolids present significant challenges for
wastewater treatment plants. High
transportation costs and reduced land
available for application combined with a
growing population leaves municipalities with
few options.

3. Additionally, because of their high water
content, biosolids are extremely costly to
transport, limiting transportation for land
application.

4. In fact, each year, an estimated
7 million tons of biosolids are produced in
the U.S. alone.1

5. In fact, each year, an estimated
7 million tons of biosolids are produced in
the U.S. alone.1
If 15% of that was landfilled, at an
average cost of $35/Ton, that would cost
municipalities $36,750,000 for landfilling
each year, with the bulk of the cost
associated with the transportation of the
high water content.

6. The Solution?

7. Reuse.

8. Through granulation, biosolids can be
transformed into a dry, granular product that
is nearly odor-free with minimal dust, but still
rich in nutrients and organic matter.

9. Benefits to this
Approach

10. The granulation of biosolids offers numerous
benefits, both economically, and
environmentally…

11. Improved Product Handling
Granules are more easily transported,
handled, and applied.

12. Reduced Waste Management Costs
Dry granules are much less costly to
transport than raw biosolids because of
the reduced moisture content.

13. Reduced Runoff
Dry granules can aid in the prevention of
runoff, because they can be used only as
needed, and don’t add additional
moisture to the soil, which can increase
opportunity for runoff to occur.

14. Premium Product
The granulation of biosolids creates a
premium product. Additives can be
included in the process to create custom
fertilizer blends, allowing the product to
be tailored to specific soil needs and
nutrient management programs, or to be
sold as a marketable product.

be tailored to specific soil needs and
nutrient management programs, or to be
sold as a marketable product.
Biosolids are also a valuable source of
organic matter and both macro and
micronutrients.

16. Additional Source of Revenue
This can not only reduce waste
management costs, but can also create
an additional source of revenue.

17. Enhanced Nutrient Management
Granular fertilizer makes it easier to
effectively follow and monitor application
rates for a nutrient management program.
It is also a valuable tool in precision
agriculture applications, where a granular
product provides improved dispensing
capabilities.

18. Conclusion
While biosolids do present significant
challenges in their current form, the reuse of
biosolids as a fertilizer or soil amendment
product through the process of granulation
offers many benefits, both environmentally and
economically.
