The Straight Poop on Manure Pelletizing

Pin Mixer PRO-CM
The Pin Mixer PRO-CM converts chicken manure into organic fertilizers and soil amendments with moisture-retention properties. One machine can process 0.3 to 50 tons/hour.

The need to dispose of large quantities of poultry litter in a manner that’s both cost-effective and environmentally acceptable has led many poultry and egg producers to re-purpose this waste into valuable organic fertilizer for agricultural, commercial and consumer applications.

For thousands of years, organic fertilizers from animal manures have been the main source of soil nourishment in many parts of the world. Organic fertilizer made from composted poultry manure is an effective alternative to expensive chemical-based fertilizers that have become widely used in the United States and other developed countries for the past century.

Poultry manure, especially, is an effective combination of a fertilizer and natural soil amendment that fosters higher seed germination rates, plant growth and crop yields. It is also an effective moisture retention aid that can help cut water use by as much as 15%. These advantages make organic fertilizers particularly valuable for farms, golf courses, commercial landscaping and home gardening.

The process to convert animal manures, especially poultry manure, into a usable fertilizer starts with composting, which kills any bacteria, viruses or other disease-causing organisms (pathogens) that may be present. It also includes reducing the manure’s moisture content below 35%. Composted manure may then be shaped into spherical pellets for easier transport and more effective spreading than bulk form allows.

Making the Best Decision

To determine the optimal pelletizing system for your needs, you should test a material in sample quantities. (5- or 10-gallon discs or drums, or 15- to 25-gallon pin mixers) After we mix the batch, we can help you analyze the results. If tests results indicate you can begin pilot scale development (e.g., 55-gallon drums), we can help with that, as well.

Part of the pilot phase includes determining the most effective binders (water and two additives, usually) to keep your pellets intact.

As for special conditions, there are none in the research phase. In the pilot phase, however, milling, pre-treatment, mixing, special feeding, drying, screening and post-treatment could be considerations.

Moving Ahead

Whether you should turn poultry manure into fertilizer pellets is a choice based on the type of cost-benefit analysis you would perform in deciding whether to make other capital investments. As an experienced and honest partner, we can help you determine if pelletizing poultry manure is the best way for you to go.
