Recycling of biosolids improves soil quality and crop health and increases crop yields.
The ability to absorb and store moisture is improved by the use of biosolids, reducing irrigation needs and providing natural drought resistance to soil.
As opposed to the production of inorganic fertilizers, biosolids sequester carbon in the soil and thereby reduce green house gases (GHG) emissions and energy consumption.
Deforested areas, open mines and ravaged land can be helped with the use of biosolids.
Biosolids when treated for use as a supplemental fuel source help decrease the use of coal. Anaerobic digestion, used in treating almost all biosolids produces methane which in turn is used as a power source for treatment plant operations. Excess power can be also sold to the grid.
Biosolids used at landfills as alternative daily or final cover reduce the use of clean soil and other valuable materials.
