Black Soldier Fly (BSF) farming has developed from a niche agricultural activity into an emerging component of the circular bioeconomy. The Black Soldier Fly, Hermetia illucens, can convert suitable organic materials into insect biomass, protein-rich meal, fat and frass.
The increasing global demand for protein for humans and animals has stimulated interest in insect farming as a complementary source of protein. In 2026, regulatory authorities and researchers continue to examine how insects can safely utilise selected food-chain residual streams while producing useful feed ingredients. EFSA published a 2026 technical assessment concerning insects reared on former foodstuffs as raw material for animal feed, reflecting the growing importance of this area.
BSF farming is particularly attractive because it can potentially combine three activities:
-
Organic-residual management
-
Protein and lipid production
-
Production of agricultural fertiliser from insect frass
The commercial opportunity therefore extends beyond selling insect meal. A properly designed BSF operation can develop several revenue streams from the same biological production system.
1. Introduction
The world's demand for protein is increasing while conventional agricultural systems face pressure from land availability, climate change, water consumption, feed costs and competition for agricultural resources.
Traditional livestock production requires significant quantities of feed. At the same time, food processing, agriculture and other industries generate large quantities of organic residual materials.
Black Soldier Fly farming offers a biological approach to converting suitable organic substrates into valuable biomass.
The larvae of the Black Soldier Fly consume organic material and convert part of it into body mass. The harvested larvae can then be processed into protein meal and insect oil, while the remaining material can potentially be processed into frass-based soil amendments, subject to applicable regulations.
2. What Is the Black Soldier Fly?
The Black Soldier Fly is a non-pest insect species widely studied for biomass production.
The adult insect does not have the same feeding behaviour as many pest flies. Commercial production focuses primarily on the larval stage because larvae have a high capacity to consume and convert suitable organic substrates.
A simplified production cycle is:
Eggs
↓
Larvae
↓
Growing larvae
↓
Pre-pupae
↓
Pupae
↓
Adult flies
↓
Egg production
↓
New larvae
A commercial farm therefore requires controlled systems for breeding, incubation, larval production, harvesting and processing.
3. The BSF Production Process
3.1 Breeding
Adult flies are maintained in a controlled environment where temperature, humidity and lighting are managed to encourage mating and egg laying.
Eggs are collected and transferred to an incubation system.
3.2 Egg Incubation
The eggs hatch into young larvae.
The larvae are introduced to prepared feed substrates and transferred to a nursery or early-growth production system.
3.3 Larval Growth
This is the main biomass-production stage.
Larvae consume the prepared substrate and increase rapidly in size.
Important production parameters include:
-
Temperature
-
Humidity
-
Feed composition
-
Feed moisture
-
Feeding frequency
-
Larval density
-
Hygiene
-
Air circulation
-
Substrate quality
3.4 Harvesting
When larvae reach the desired development stage, they are separated from the residual substrate.
Depending on the business model, the larvae can be:
-
Sold alive
-
Dried
-
Processed into insect meal
-
Processed into insect oil
-
Used in animal-feed formulations
3.5 Processing
The harvested larvae may undergo:
-
Cleaning
-
Drying
-
Milling
-
Separation
-
Oil extraction
-
Protein concentration
The final products may include:
-
Whole dried larvae
-
BSF meal
-
Defatted BSF meal
-
Insect oil
-
Protein concentrate
-
Frass
4. Protein Production
The most important commercial product from BSF farming is protein-rich insect biomass.
Insect meal can potentially be used as an ingredient in feed formulations, depending on the animal species and applicable regulations.
Potential markets include:
-
Aquaculture
-
Poultry
-
Pet food
-
Livestock feed
-
Specialty animal nutrition
The exact permitted uses depend on the jurisdiction, substrate used and regulatory classification.
5. Circular Economy Opportunity
One of the strongest arguments for BSF farming is its potential contribution to the circular economy.
Instead of viewing suitable organic residual materials exclusively as waste, they can potentially become inputs into a biological production system.
The model can be represented as:
Organic residuals
↓
BSF larvae
↓
Protein + oil
↓
Animal feed / other approved applications
Residual material
↓
Frass
↓
Agricultural soil amendment / fertiliser applications where permitted
This creates the possibility of producing multiple valuable outputs from one production system.
6. BSF Farming in Africa
Africa presents potentially attractive conditions for insect farming because of:
-
Growing populations
-
Rising demand for animal protein
-
Increasing poultry production
-
Expanding aquaculture
-
High demand for affordable animal feed
-
Availability of suitable agricultural and food-processing residuals
-
Need for alternative protein sources
-
Growing interest in circular agriculture
Countries with strong poultry and aquaculture sectors may provide particularly attractive markets.
Ghana could potentially develop a BSF industry around agricultural and food-processing value chains.
Potential feedstock sources include appropriately controlled:
-
Fruit and vegetable residuals
-
Brewery by-products
-
Food-processing residuals
-
Selected agricultural by-products
However, substrate selection must be carefully controlled because contamination can affect insect safety and the legal status of the resulting products.
7. Business Model
A commercial BSF enterprise can generate revenue through several products.
Revenue Stream 1: Insect Meal
Processed insect meal can be marketed to animal-feed manufacturers.
Revenue Stream 2: Insect Oil
The lipid fraction can potentially be sold into approved feed and other industrial applications.
Revenue Stream 3: Live Larvae
Live larvae may be sold for specific animal-feed applications where legally permitted.
Revenue Stream 4: Frass
Frass may have value as an agricultural soil amendment or fertiliser product, subject to local regulations.
Revenue Stream 5: Organic Residual Processing
Depending on the regulatory framework, businesses may potentially charge customers for processing suitable organic residual materials.
8. Required Infrastructure
A commercial BSF farm requires more than insect-rearing rooms.
A professional facility may include:
-
Breeding room
-
Egg collection area
-
Nursery
-
Larval production hall
-
Feed preparation area
-
Harvesting equipment
-
Separation equipment
-
Drying equipment
-
Milling equipment
-
Oil-extraction equipment
-
Cold or controlled storage
-
Packaging facilities
-
Laboratory/quality-control facilities
-
Waste-management systems
-
Worker hygiene facilities
Automation becomes increasingly important as production volume increases.
9. Quality Control and Biosafety
Quality control is one of the most important elements of commercial insect production.
A professional operation should establish procedures covering:
-
Substrate traceability
-
Microbiological testing
-
Heavy-metal monitoring
-
Pesticide/chemical contamination
-
Pathogen control
-
Moisture control
-
Protein analysis
-
Fat analysis
-
Storage conditions
-
Batch traceability
Regulations governing insect production differ between countries.
Companies planning to sell BSF products internationally must therefore determine the precise legal requirements for the destination market.
10. Environmental Benefits
Potential environmental advantages include:
-
Biological conversion of suitable organic residuals
-
Production of protein without conventional livestock production
-
Potential reduction in dependence on some conventional feed ingredients
-
Production of multiple outputs from one biological process
-
Potentially efficient use of space
-
Integration with circular agricultural systems
These benefits should nevertheless be measured rather than assumed. Energy use for heating, drying, processing and transportation can significantly affect the environmental footprint.
11. Major Challenges
The main challenges include:
11.1 Feedstock Consistency
Larvae require a consistent and safe substrate.
11.2 Climate Control
Temperature and humidity strongly influence production.
11.3 Energy Costs
Drying insect biomass can require substantial energy.
11.4 Market Development
Feed manufacturers need consistent quality, price and supply.
11.5 Regulation
Rules concerning substrates, processing and final use must be followed carefully.
11.6 Scale
Small farms may have difficulty competing with industrial feed ingredients unless they develop local advantages.
12. Investment Considerations
A BSF project should not begin with the question:
"How many insects can we produce?"
The better question is:
"Who will buy the protein, oil and frass, and what price will they pay?"
Before investment, a feasibility study should establish:
-
Feedstock availability
-
Feedstock cost
-
Production capacity
-
Facility cost
-
Energy requirements
-
Labour requirements
-
Processing cost
-
Product selling price
-
Transport costs
-
Regulatory requirements
-
Target customers
-
Financing requirements
13. Recommended Commercial Strategy

14. Conclusion
Black Soldier Fly farming represents an important opportunity at the intersection of agriculture, waste/resource management and alternative protein production.
Its strongest commercial advantage is the possibility of producing multiple products from one biological system.
However, successful BSF farming should be approached as a professional feed and biotechnology business, not simply as insect farming.
The future of the sector will depend on:
-
Production efficiency
-
Feed safety
-
Processing technology
-
Regulatory compliance
-
Customer acceptance
-
Cost competitiveness
-
Reliable supply chains
In 2026, interest in insect protein remains connected to the broader global effort to develop additional protein sources and more circular food and feed systems.
For Africa, and particularly countries with strong poultry, aquaculture and agricultural sectors, BSF production could become an important component of a diversified protein and feed strategy.
