Composted manure and Bio-Solids are products without a good place in the landfill or the farm. The odor and knowledge of where it comes from keeps high quality fertilizer dumped in landfills, instead of being sold to farms. Landfills that receive Bio-Solids must quickly bury them to reduce the odors that they come with. The landfills probably don’t mind the money they are being paid, but they don’t necessarily like the product. Farmers might like the nutrient value but cannot accept the bacteria and the odor.
Problems associated with Bio-Solids and Compost:
-Compost and Bio-Solids smell due to Ammonia (from urea degradation) and Hydrogen Sulfide (from protein digestion by anaerobes). Then, there is the poopy smell of mercaptans (organic sulfur compounds).
-Hauling it away is a problem due to its odor. A truck hauling Bio-Solids can stink up a city block or more just driving down the road. Cities regulate their transport across towns to keep the odor down.
-The perception of what Bio-Solids are is just as bad. People complain even if you are just storing it for de-watering purposes.
-Some bacteria survive the Composting process, getting incorporated and contaminating the growing food. Farmers don’t want this type of Compost for sensitive crops.
-Bio-Solid solidification with fly ash or earths is effective in lowering the odor, and treatments with heat can lower the moisture content and kill the bacteria. But some odor persists.
-Many farms are overloaded with options of receiving smelly wastes. Some farms, though, have had enough. Their image is smeared as well for receiving and plowing stinky stuff into their soils.
What can Compost-Stinger do?
-Pretreatment of Sludge in the digestor will densify the waste. Silty materials will settle without stratification caused by organic cell skeletons
-The decrease in stratification and layering means more dewatering, thereby the sludge takes up less space.
-For biogas generation, there would be a higher gas yield, as punctured cell walls collapse, releasing more organic materials for bacterial digestion.
-Sludge would be less sticky (glue-like solids are normally protein-based compounds). Less stickiness means easier handling, less pocketing of water, so less water retention.
-And all this while removing Ammonia and Hydrogen Sulfide odors and leaving a pleasant masking fragrance behind.
-Farmers who have used this Compost say that it smells like grass or green tobacco when they spread it in their fields.
-While preserving the fertilizer components of the sludge compounds, Compost-Stinger reduces biological toxins and bacterial sources in the sludge, allowing it to behave like soil rich in nutrients.
-Reduces liability when storing large quantities of Bio-Solids materials. The neighbors won’t complain so much about the smell.
