6T/H Modern Fresh Chicken Manure Fertilizer Factory in Uruguay

Project Background and Investment Rationale

Uruguay boasts a robust and expanding agricultural sector, with poultry farming being a significant component. However, the concentration of poultry operations leads to substantial quantities of chicken manure, which, if not managed properly, can pose environmental risks. Simultaneously, continuous cropping depletes soil organic matter, creating a growing demand for organic fertilizers to maintain soil fertility and structure. The client, a consortium of local farmers and agribusiness professionals, identified an opportunity to bridge this gap.

The decision to invest in this fresh chicken manure fertilizer factory in Uruguay was driven by a clear market need and supportive regulatory environment. The government encourages agro-industrial projects that add value to local products and promote environmental sustainability.

The primary goal was to establish a facility capable of processing 30,000 tons of organic fertilizer annually (approximately 6 tons per hour, based on an 16-hour operational day), using locally sourced, low-cost raw materials. The final product is a premium, pelletized organic fertilizer that meets stringent national quality standards, destined for sale to commercial farms and horticultural centers across Uruguay and for potential export to neighboring Mercosur countries.

Project Location and Infrastructure

The fresh chicken manure fertilizer factory in Uruguay is situated on a 4,000 m² plot in a rural-industrial zone near the city of Durazno. This location was selected for its strategic advantages, which are critical to the project's logistics and economic viability.

• Proximity to Raw Materials: The region is a hub for poultry production, ensuring a consistent and low-cost supply of fresh chicken manure. Furthermore, it is surrounded by large-scale grain farms, providing easy access to straw and other carbon-rich amendments.
• Transportation Access: The site has direct connectivity to national highways, facilitating the efficient inbound collection of raw materials and outbound distribution of the finished fertilizer to key agricultural markets.
• Minimized Nuisance: The facility is located at a sufficient distance from residential areas, mitigating potential concerns related to odors during the initial composting phase, which is proactively managed through advanced containment and treatment systems.

The project involved the construction of a single-story main production shed, a raw material storage area, and a small office building. The site is serviced by a reliable grid electricity connection and a dedicated groundwater well for process and sanitary water needs.

Production Process and Technology

The core technology behind this fresh chicken manure fertilizer factory in Uruguay is controlled aerobic composting. This biological process harnesses microbial activity to stabilize organic matter, eliminate pathogens, and transform waste into a nutrient-rich, humus-like substance. RICHI Machinery provided a complete production line that optimizes this natural process for industrial-scale efficiency and environmental control.

The production workflow is a carefully orchestrated sequence of mixing, composting, and refining, as outlined below.

Raw Material Preparation and Mixing: The success of the composting process depends on creating an optimal blend of nitrogen-rich (fresh chicken manure) and carbon-rich (straw, wood shavings, etc.) materials. Upon delivery, the raw materials are stored in designated, partially enclosed areas. The fresh chicken manure (with an initial moisture content of around 60%) is mixed with bulking agents like straw and wood shavings. This blend is crucial for achieving the right Carbon-to-Nitrogen (C:N) ratio and porosity for effective aeration. A specialized RW functional microbial inoculant is evenly spread onto the mixture to accelerate the decomposition process.

Aerobic Composting (Windrow Fermentation): The mixed materials are formed into long, narrow piles known as windrows inside a fully enclosed fermentation hall. A RICHI wheeled turner machine regularly traverses these windrows, performing two critical functions:

1. Aeration: It turns and fluffs the pile, injecting oxygen essential for the aerobic microbes to thrive.
2. Homogenization and Cooling: It ensures even decomposition and prevents the core temperature from rising to levels that would be detrimental to the microbial community.

The composting process proceeds through three distinct biological phases:

• Mesophilic Phase: Initial decomposition by moderate-temperature microbes.
• Thermophilic Phase: The temperature rises to 60-70°C, where thermophilic bacteria become dominant, rapidly breaking down proteins, fats, and complex carbohydrates while effectively eliminating pathogens and weed seeds.
• Curing Phase: As the most readily decomposable materials are consumed, the temperature gradually decreases. The compost matures and stabilizes into a nutrient-rich humus over a period of approximately 20 days.

Crushing, Screening, and Granulating: The cured compost is then conveyed to a crusher to break down any clumps, ensuring a uniform consistency. The material is screened to separate oversized particles, which are recycled back to the crusher. The fine, consistent material is then fed into a chicken manure pellet machine, where it is compressed and shaped into dense, uniform pellets. This granulation process improves the product's handling, storage, and application properties.

Packaging and Storage: The final pelletized organic fertilizer is automatically weighed and bagged into 25kg or 45kg sacks using a double-head packaging system. The bagged product is then palletized and stored in the finished product warehouse before shipment.

Environmental Protection Measures

A cornerstone of this organic fertilizer production project's design is its commitment to minimizing environmental impact. The fresh chicken manure fertilizer factory in Uruguay incorporates several key measures to manage emissions, waste, and noise.

• Odor Control: The most significant potential emission is odor from the active composting phase. To mitigate this, the entire fermentation hall is fully enclosed and maintained under negative pressure. Fugitive gases are captured and treated through a multi-stage system: first, a RW functional bacteria bio-filter for biological degradation of odors, followed by a chemical scrubber (spray tower) for final polishing. The treated air is then released through a 15-meter high exhaust stack, ensuring dispersion and compliance with air quality standards.
• Dust Management: Dust generation during crushing and screening is controlled by operating these processes within the semi-enclosed main production hall. The conveyor system is fully enclosed. Any settled dust is regularly cleaned and can be reintroduced into the production process.
• Water Management: The facility operates on a rainwater and sewage separation system. Process water use is minimal, primarily for moisture adjustment during composting. Sanitary wastewater from the small staff is treated in a septic tank system, with the effluent safely dispersed via a subsurface infiltration field, in line with local regulations.
• Solid Waste Management: All process waste, such as plastic packaging from raw materials, is segregated and sold to recycling companies. General waste from the office is collected by municipal services.
• Noise Control: Equipment selection prioritized low-noise models. Additionally, machines are installed on vibration-damping bases, and the building itself provides acoustic insulation.

Economic and Operational Details

• Total Investment: The total capital expenditure for establishing this fresh chicken manure fertilizer factory in Uruguay was approximately $215,000 USD. This investment covered site development, construction, the complete RICHI machinery package, and the environmental control systems.
• Work Schedule: The plant operates with a lean team of 10 personnel, working a  two 8-hour shift, 300 days per year. There is no night shift.
• Staffing: The operational model is designed for efficiency, with staff responsible for monitoring the composting process, operating machinery, and managing logistics.

Market Prospects for Organic Fertilizer in Uruguay

The market outlook for the output of this fresh chicken manure fertilizer factory in Uruguay is exceptionally strong. Uruguay's economy is heavily dependent on agriculture, and there is a growing trend towards sustainable practices.
