Problem

Manure Hazards: Goat and sheep manure may contain human pathogens and weed seeds, posing hazards to crops and the environment.
Inefficient Nutrient Utilization: Nutrients in goat and sheep urine are often wasted, and improper manure handling can lead to environmental pollution.

Solution

Composting: Composting rapidly deactivates human pathogens and weed seeds in manure, making it safe for use as compost on vegetable crops.
Value-Added Processing: Commercial technologies are available to produce organic fertilizers from goat and sheep manure, increasing its economic value and reducing waste.
Improved Nutrient Utilization: Keeping goats and sheep in pasture-based systems allows for the collection of manure, which can be dried and stored for use. This method efficiently utilizes nutrients while mitigating hazards.

Key points to design your business plan

The Processing and Application of Composted Manures technology may be of interest to Manufacturers, and users (farmers).

Manufacturers

Developing the Processing and Application of Composted Manures technology presents an opportunity to revolutionize agriculture and promote sustainability. To effectively implement this technology, consider the following steps:

Invest in composting equipment suitable for your scale of operations.
Analyze the composition of manure and identify any nutritional or processing constraints.
Evaluate the cost and availability of raw materials in your local area.
Ensure compliance with environmental and sanitary regulations for operating a processing facility.

As key partners, suppliers of composting equipment and raw materials for compost production are essential for successful implementation.

Calculate the necessary equipment for your project, considering costs and logistics. Manure drying and composting equipment able to process between 5 and 10 tons per day cost about 5,000 to 10,000 USD, including installation. Consider delivery expenses, import clearance, and applicable duties as this technology is accessible in multiple countries like Cameroon, Ethiopia, Kenya, Somalia, South Sudan, Tanzania, Uganda, Burkina Faso, Mali, Niger, Nigeria, Senegal, Zimbabwe.

Engage a team of trainers to provide comprehensive support during installation and operation. Develop communication materials to raise awareness of the benefits of composted manures.

Collaborate with breeders and local stakeholders to tailor services to market needs. Your potential customers are farmers, resellers, NGOs and development agencies

Users

Implementing the technology of Processing and Application of Composted Manures offers a sustainable solution for managing organic waste and improving soil fertility, thereby enhancing agricultural productivity and reducing environmental pollution.

As key partners, compost suppliers are essential for successful implementation.

Since the technology is accessible in various countries such as Cameroon, Ethiopia, Kenya, Somalia, South Sudan, Tanzania, Uganda, Burkina Faso, Mali, Niger, Nigeria, Senegal, and Zimbabwe, it's crucial to consider delivery costs and potential import duties.

The cost structure varies with the cost of compost.

Assessing the profitability and environmental benefits achieved through the utilization of this technology is essential.

Goal 2: zero hunger

Goal 8: decent work and economic growth

Goal 13: climate action

The production of organic fertilizer pellets from composted goat and sheep manure involves the following steps:

Crushing: The composted manure is crushed using a hammer mill capable of processing semi-wet materials.
Screening: Screening is performed either in batches or continuously along a conveyor belt. Oversized materials are reprocessed through the crusher.
Pelletizing: The fine material is pelletized by introducing small amounts of added water and applying friction through stirring. Alternatively, a vibrating granulating pan or extrusion may be used for pellet formation.
Secondary Screening: After pelletization, a second screening process is carried out to collect undersized materials for potential reuse.
Drying: Drying of the newly formed pellets is achieved most effectively by passing them along a heat tunnel conveyor. However, in some cases, air drying may be employed.
