The Value of Turning Animal Manure into Fertilizer
Turning animal manure into fertilizer is an innovative agricultural solution that transforms a disposal problem into a profitable and eco-friendly opportunity. Livestock and poultry farms generate millions of tons of manure annually, much of which goes to waste or creates environmental hazards. Converting this waste into nutrient-rich fertilizer not only reduces pollution but also creates a marketable product for domestic and international agriculture.
According to the latest market data, it is projected that by 2030, the global market size of organic fertilizers will reach 15.9 billion US dollars. This is attributed to the increasing demand for sustainable agricultural practices and the decreasing usage of synthetic fertilizers. Granular organic fertilizers are becoming increasingly popular due to their ease of application, high storage stability, and stable nutrient content.
Feasibility – Why This Approach Works
Turning animal manure into fertilizer is feasible for both small-scale farms and large agribusiness operations because:
Factor | Insight |
Abundant Raw Material | Cattle, poultry, and pig farms produce continuous supplies of manure. |
Proven Technology | Established fertilizer production equipment ensures consistent product quality. |
Government Support | Many regions offer subsidies for manure recycling to reduce environmental impact. |
High Market Demand | Farmers seek eco-friendly fertilizers to meet organic certification requirements. |
Strong Profit Margins | Organic fertilizer sells at higher prices compared to raw compost. |
In the EU, for example, farmers can receive grants for installing organic waste recycling systems. In the U.S., the USDA supports manure-to-fertilizer projects to promote sustainable agriculture.
How the Process Works – Step-by-Step
The process of turning animal manure into fertilizer follows a well-structured sequence, supported by specialized equipment at each stage. Here’s how it works:
1.Collection and Raw Material Preparation
Fresh manure is collected from livestock barns, poultry houses, or feedlots and transported to the processing site. Large debris such as stones, bedding straw, or plastic is removed using a rotary screen machine to ensure the raw material is clean and ready for further processing. This step ensures a smooth flow in the subsequent production stages.
2.Crushing for Uniform Particle Size
The pre-cleaned manure is fed into a semi-wet material crusher to break down clumps and create a consistent particle size. Uniformity at this stage is critical for effective composting and granulation, as it improves mixing efficiency and pellet quality.
3.Composting and Fermentation
The crushed manure is formed into long windrows or placed inside fermentation tanks. Using a crawler type compost turner or groove type compost turner, the material is regularly aerated to provide oxygen to the microbes, speeding up decomposition. During this process, internal temperatures naturally rise to 55–65°C, killing pathogens, parasite eggs, and weed seeds while preserving beneficial microorganisms.
4.Nutrient Blending and Moisture Adjustment
Once composting is complete, the material is transferred to a horizontal fertilizer mixer. Here, it can be blended with crop residues, humic acid, or additional nutrients such as nitrogen, phosphorus, and potassium. Moisture content is also adjusted to the optimal level for granulation—typically between 30–35%.
5.Granulation – Forming Fertilizer Pellets
The blended material enters the granulation stage. Depending on production needs and material characteristics, one of two methods is used:
Dry Granulation: A double roller granulator compacts the material into pellets without adding extra moisture, making it energy-efficient and suitable for medium-moisture compost.
Wet Granulation: A new type organic fertilizer granulator uses mechanical stirring and water to shape durable, high-density pellets ideal for higher-moisture materials.
6.Drying to Preserve Quality
Freshly granulated fertilizer is passed through a rotary drum dryer to reduce moisture content to around 10–15%. This step extends shelf life, prevents mold growth, and improves pellet strength.
7.Cooling to Stabilize Pellets
The hot pellets from the dryer are fed into a counter-flow cooler. Rapid cooling stabilizes the pellet structure, prevents caking during storage, and ensures the product is safe to bag immediately.
8.Screening for Consistent Product Size
A rotary drum screener separates fine powder and oversized pellets from the finished product. Oversized pellets are crushed and returned to the granulator, while fine powder is recycled into the mixing stage.
9.Packaging for Storage and Sale
Finally, the uniform fertilizer pellets are weighed and packed using an automatic fertilizer packaging machine. Bags are sealed to protect against moisture and contamination, ready for transport to farms or distribution centers.
Applications – Where This Fertilizer Is Used
Turning animal manure into fertilizer produces a nutrient-rich product that is highly versatile and supports a wide range of agricultural applications. Its organic matter content, slow nutrient release, and pathogen-free quality make it an essential input for sustainable farming systems worldwide.
Field Crop Farming – Farmers use turning animal manure into fertilizer products for wheat, corn, rice, and other grains. This improves soil aeration, boosts nutrient availability, and enhances root development for higher yields.
Vegetable and Fruit Cultivation – Ideal for tomatoes, cucumbers, peppers, grapes, and orchard crops. Fertilizer made by turning animal manure into fertilizer enriches soil, improves water retention, and enhances the taste and shelf life of produce.
Pasture and Forage Grasslands – Supplies balanced nutrition to promote healthy grass growth, improving feed quality for dairy cattle, beef cattle, sheep, and goats.
Greenhouse Agriculture – Odor-free and pathogen-free pellets from turning animal manure into fertilizer are safe for controlled farming environments and reduce disease risk.
Organic Certified Farms – Complies with organic farming standards in many regions, giving farmers access to premium markets and higher returns.
Land Restoration and Landscaping – Rehabilitates degraded soils in mining areas, construction zones, and public green spaces, adding organic matter and long-lasting fertility.
