EcoCycle Larvae System: Black Soldier Fly Larvae (BSFL) proteins for low cost animal feeds

BSFL proteins for sustainable local fish and chicken feed production

BSFL composting is a biological waste recycling method where the larvae of the black soldier fly are used to decompose various organic materials. The larvae are voracious feeders, capable of consuming a wide range of organic waste, including food scraps, agricultural by-products, and even manure. This process results in the production of nutrient-dense larvae that can be harvested and used as animal feed, as well as a nutrient-rich compost known as frass.

Problem

Feed supply issues: Fish and poultry farming in sub-Saharan Africa face inconsistent and unreliable year-round feed supplies.
High production costs: Rising feed prices significantly increase production costs, making it difficult for farmers to sustain operations.
Food waste and organic waste: A large portion of food (30-40%) is wasted, resulting in excessive organic waste and livestock manure that require proper management.
Environmental damage: Unsustainable management of organic waste leads to negative environmental impacts, such as pollution and resource depletion.
Economic and social instability: The traditional linear economy creates long-term threats to economic stability, environmental health, and social equity.

Solution

BSFL composting technology: Using Black Soldier Fly larvae to decompose organic waste provides a sustainable way to manage waste and reduce environmental harm.
Alternative feed source: BSFL technology produces nutrient-rich larvae that can be used as a low-cost, sustainable animal feed for fish and poultry, reducing dependence on expensive traditional feed.
Waste recycling: The process turns food scraps, agricultural by-products, and manure into valuable resources like protein-rich feed and compost (frass), closing the loop in the circular economy.
Environmental sustainability: By reducing landfill waste and reusing organic materials, BSFL technology helps mitigate the negative environmental impact of waste.
Circular economy promotion: Encouraging the adoption of BSFL technology supports a circular economy model that fosters long-term economic stability, environmental protection, and social equity.

Key points to design your business plan

The BSFL for fish and poultry feeds technology might interest three mains groups:

For Manufacture

Manufacturers can take advantage of BSFL Composting Technology to produce low-cost, high-protein livestock feeds using organic waste, such as food scraps, agricultural by-products, and manure.

The manufacturing process involves cultivating and harvesting Black Soldier Fly larvae, which can be processed into nutritionally rich animal feed. To integrate his technology in business, the following budget can be considered:

Composting Bins/Containers: The cost for bins or containers to house the organic waste and larvae can range from 200 to 500 USD, depending on the size and materials used.
Larvae Sourcing (Initial): Purchasing initial larvae can cost between 50 and 100 USD, depending on the supplier.
Organic Waste (Substrate): Costs for the organic waste used as feed for the larvae can vary widely, but an estimate of 100 to 300 USD can be expected, especially if sourcing from local markets or farms.
Temperature and Humidity Control: Basic systems to monitor and control environmental conditions may cost between 100 and 300 USD, depending on the complexity.
Basic Equipment: Essential tools and equipment (like scales for measuring waste and larvae) can range from 200 to 400 USD.
Labor (initial setup): Depending on the complexity of the setup and local labor costs, initial labor might cost between 100 and 300 USD.
Miscellaneous Costs: Additional costs for transportation, utilities, and other unforeseen expenses can add another 100 to 200 USD.

The total estimated cost to establish a small-scale BSFL composting facility ranges from approximately 1,000 to 2,400 USD. This budget can vary based on local conditions, specific requirements, and the scale of the operation. Adjustments may be necessary based on specific project needs and available resources.

A team of experts could provide training on managing BSFL feed production, and organic waste handling. Costs for initial training and post-training support should be included in the project budget.

Using black soldier fly larvae (BSFL) composting technology is a straightforward process that allows users to efficiently recycle organic waste into valuable feed for animals or nutrient-rich compost. Here is a step-by-step guide on how to implement this technology:

Step 1: Acquire Black Soldier Fly Larvae
You can purchase BSFL from local feed stores or online retailers. Alternatively, you may find them naturally in your garden or compost pile.

Step 2: Prepare the Composting Bin
1. Choose a Container: Select a bin that can hold organic waste and has good ventilation. A simple plastic container or a wooden box works well.
2. Create a Suitable Environment: Ensure the bin is kept in a moist, dark environment, as BSFL thrive under these conditions.

Step 3: Add Organic Waste
1. Collect Organic Waste: Gather kitchen scraps (like fruits, vegetables, and grains), and other organic materials (such as yard waste). Avoid adding woody materials or anything rich in cellulose.
2. Feed the Larvae: Add the organic waste to the bin. BSFL can consume up to 10 kg of food waste per square meter per day, so adjust the amount based on your bin size and the number of larvae.

Step 4: Introduce the Larvae
1. Bury the Larvae: Place the BSFL into the compost pile. They will burrow into the waste and begin feeding.
2. Monitor Conditions: Keep the environment moist but not soggy, and ensure good airflow.

Step 5: Maintain the Composting Process
1. Regular Feeding: Continue to add organic waste regularly. The larvae will eat about twice their body weight daily, significantly reducing the volume of waste.
2. Observe Growth: Within a few weeks, the larvae will grow rapidly and reach their final larval stage, becoming pre-pupae.

Step 6: Harvest the Larvae
1. Self-Harvesting: As the larvae mature, they will instinctively leave the food source to pupate. You can place a collection bucket at the exit point to catch them.
2. Use as Feed: The harvested larvae can be fed directly to chickens, fish, or reptiles as a protein-rich supplement.

Step 7: Collect the Compost
1. Frass Collection: The remaining material in the bin, known as frass, is a nutrient-rich compost that can be used to enrich garden soil.
2. Utilize the Compost: Spread the frass in your garden or mix it with soil to improve fertility.

By following these steps, users can effectively implement black soldier fly larvae composting technology to recycle organic waste, produce high-quality animal feed, and create nutrient-rich compost. This process not only helps in waste management but also promotes sustainable agricultural practices.
