Bio-organic fertilizer production lines are specialized systems that convert organic waste into high-quality fertilizer through microbial fermentation. Their applications are rapidly expanding with the development of green agriculture.
I. Typical Application Scenarios Classification
1. Livestock and Poultry Waste Treatment
- Large-scale farms: Supporting facilities for pig farms with annual output ≥10,000 heads or poultry farms with ≥1 million birds
- Livestock concentration areas: Processing combined waste from multiple farms in a region
- Case study: A 100,000-head pig farm supporting a 20,000-ton/year bio-organic fertilizer production line achieves complete resource utilization of manure[1]
2. Agricultural Planting Fields
- Organic agricultural product bases: Meeting strict organic certification requirements for fertilizer use
- Facility agriculture: Soil improvement needs for multi-span greenhouses, solar greenhouses, etc.
- Cash crop areas: High-value crops like tea, medicinal herbs, and fruits
- Soil remediation projects: Special projects for heavy metal-contaminated farmland and saline-alkali soil improvement
3. Urban Organic Waste Treatment
- Food waste treatment centers: Supporting facilities for projects with daily processing capacity ≥50 tons
- Sludge treatment facilities: Resource utilization of municipal sludge after harmless treatment
- Landscaping waste: Recycling of urban green waste like pruned branches
II. Technical-Economic Considerations for Scenario Selection
1. Raw Material Guarantee Factors
- Raw material stability: Continuous stable supply should reach ≥60% of production line design capacity
- Collection radius: Optimal economic collection radius ≤50km (dry basis raw materials)
- Pretreatment requirements: Moisture content should be controlled between 50-65%
2. Product Market Positioning
- High-end market: Functional bio-organic fertilizer production lines (with specific microbial strains)
- Mass market: Ordinary organic fertilizer production lines (meeting NY 884 standard)
- Customized market: Crop-specific production lines (e.g., fruit tree-specific, vegetable-specific)
3. Policy Support Conditions
- County-wide promotion projects for livestock manure resource utilization
- Organic fertilizer substitution demonstration counties
- Agricultural green development pilot zones
Practice shows that when raw material concentration reaches ≥300 tons/day (wet basis), establishing specialized bio-organic fertilizer production lines demonstrates significant economic and environmental benefits. For example, a poultry manure treatment project with 50,000-ton annual output has an investment payback period of about 3-4 years[2].
III. Innovative Application Scenario Expansion
1. Crop-Livestock Circular Models
- “Pig-fertilizer-fruit/vegetable” regional circular systems
- Rice-fish integrated farming supporting systems
2. Special Functional Applications
- Biocontrol organic fertilizer production (containing antagonistic bacteria)
- Saline-alkali soil improvement-specific organic fertilizer production
- Mining area ecological restoration substrate production
3. Distributed Treatment Models
- Mobile fermentation equipment for scattered farmers
- Community food waste on-site treatment facilities
IV. Scenario Adaptation Recommendations
| Scenario Type | Recommended Production Line Scale | Key Equipment Selection |
| Large livestock enterprises | ≥50,000 tons/year | Tank aerobic fermentation system + drum granulation |
| County treatment centers | 10,000-30,000 tons/year | Windrow turning + disc granulation |
| Facility agriculture parks | 5,000-10,000 tons/year | Membrane-covered fermentation + extrusion granulation |
