Poultry manure is one of the main problems in poultry farming, and if it is not handled correctly, it can lead to a serious environmental problem. However, thanks to scientific management and processing methods, this seemingly gaseous substance can be turned into a valuable resource. In this article, we take a closer look at the various aspects of poultry manure, how to dispose of it and the economic opportunities.

1. Composition and properties of chicken manure
Poultry waste is a mixture of faeces, urine, feathers, feed residues and leaf litter. Their chemical composition varies depending on the type of farm (chicken, broiler or chicken). On average, each laying hen produces about 55-60 kg of faeces per year, and each broiler chicken produces about 3-4 kg of faeces during the growing period.
Key Ingredients:
-
Nitrogen (1.5-3.5%)
-
Phosphorus (0.8-2.5%)
-
Potassium (0.7-2%)
-
Organic matter (60-80%)
-
Humidity (20-40%)
2. Environmental problems of bird droppings
(a) Water pollution:
-
Nitrates seep into groundwater.
-
Phosphorus enters surface waters and causes eutrophication.
-
Contamination by pathogenic bacteria such as salmonella
b) Air pollution:
-
Emissions of toxic gases (ammonia, hydrogen sulfide)
-
Production of greenhouse gases (methane and carbon dioxide)
-
produces an unpleasant odor
c) Soil pollution:
-
Accumulation of heavy metals
-
soil salinization
-
Nutritional imbalance
3. Traditional methods of waste management
a) Direct use as fertilizer:
-
Initial fertilization is required
-
Risk of disease transmission
-
Ammonia can cause plant burns.
b) Funeral:
-
expensive and unhealthy
-
Risk of groundwater contamination
c) Combustion:
-
loss of nutrients
-
Generation of air pollutants
4. New technologies for processing poultry waste
a) Advanced fertilization:
-
Use a forced ventilation system
-
Automatic temperature and humidity control
-
Reduce processing time from months to weeks
b) Industrial Dryer:
-
Reduce size and weight
-
Eliminate pathogens
-
More durability
c) Solid-liquid separation system:
-
Production of liquid and solid fertilizers
-
Improve Utilization
5. Waste-to-energy (biogas)
Anaerobic digestion process:
-
Biogas production (60-70% methane)
-
Reduce waste to 50%
-
Production of high-quality liquid fertilizers
peculiarity:
-
Power Supplies for Agricultural Implements
-
Reducing greenhouse gas emissions
-
Generating income through the sale of energy
test:
-
High initial investment
-
Technical knowledge required
-
System Maintenance and Operation
6. Use cow manure to produce organic fertilizer.
Standard stages of organic fertilizer production:
-
Basic assembly and separation
-
Fertilization time: 4 to 8 weeks
-
Drying and sieving
-
Nutrition Testing & Modification
-
Packaging & Shipping
Advantages of chicken manure:
-
Improving soil structure
-
increased microbial activity
-
Provide nutrients gradually
-
Reduction of fertilizer use
7. Industrial application of waste processing
a) Production of animal feed:
-
Protein extraction
-
Use in ruminant nutrition
b) Production of industrial raw materials:
-
Enzyme Extraction
-
Bioplastics production
c) Applications of biotechnology:
-
Antibiotic production
-
Algae cultivation
8. Waste Management Laws and Regulations
(a) Environmental standards:
-
Heavy Metal Limit
-
Emission standards
-
Storage and Transportation Rules
b) Fertilizer standards:
-
Carbon-to-nitrogen ratio
-
Minimum fertilization time
-
Minimum process temperature
c) Safety rules:
-
Protecting Workers
-
Fire prevention
-
Pathogen control
9. Conclusion and prospects for the future
Scientific management of poultry waste is not only an environmental necessity, but also an economic opportunity for poultry farmers. Future development of the industry:
-
Development of an integrated waste management system
-
Improve energy conversion efficiency
-
Extraction of high value-added materials
-
Reduced operating costs
It is an influential sector. Investing in it can solve environmental problems and open up new sources of income for poultry farmers.
Frequently Asked Questions:
-
Is chicken manure suitable for all plants?
No, some plants that are sensitive to salt or ammonia may be affected. It is best to use a carefully selected fertilizer. -
How to reduce the smell of chicken manure?
Proper composting, the use of absorbent materials such as zeolite, and humidity control can help reduce odors. -
Can chicken manure completely replace chemical fertilizers?
No, but it covers 50% to 70% of plant needs and reduces the use of chemical fertilizers.
