The economics of black soldier fly production
Transcript of The economics of black soldier fly production
Reduced feeding costs
Larvae can be fed directly (live) to
High quality soil amendment
The composting process sufficiently reduces nutrient levels in the manure so that the residual can be directly applied as a soil amendment in larger quantities than fresh manure.
Small-scale production system
Outputs are used on-farm
Revenue is derived from reducing costs
Does not require larvae refining equipment
With black soldier fly composting, one dry ton of organic waste can be converted into...
Between 160 and 400 pounds of dry larvae
$48 - $120 as a substitute for grain-based protein feeds
$112 - $288 as a substitute for fish meal
Between 1200 - 1600 pounds of residual compost / fertilizer
Refined animal feed (approximate prices from USDA):
$1,441 per ton for fish meal (60% protein)
$600 per ton for swine and poultry protein feed
Values would be higher if the feed becomes certified organic!
$4 per gallon as biodiesel
$7 per gallon as an industrial lubricant
$168 per ton
Value depends in part upon the input waste
Benefits of refinement
Increases the protein content from 42% to 62%
Refined larvae can be used in larger quantities as a feed substitute
Control over the final nutrient content of the feed
Dried pellets are more storable than fresh larvae
The lipids can be sold or processed into biodiesel
Large-scale production system
Outputs are used on-site, not sold on the open market
Revenue is derived from reducing costs
Larvae are refined into multiple outputs
How much money can you expect to make (save) by composting a ton of manure?
Should you refine larvae on-site?
What is the value of a pound of larvae?
It depends upon...
Quantity and type of organic waste,
Does black soldier fly composting make economic sense for your farm?
Manure management expenses before and after implementing a composting system,
Cost of animal feed,
The structure of the farm: concentrated or dispersed,
I'll stop there.
Substantial startup / capital costs
Oil expeller press
Biodiesel production equipment
Requires skilled labor
Only viable for large concentrated animal farms or large-scale food production operations
Individual farmers produce larvae
A centralized refiner pays the farmers to collect larvae
The refiner sells the outputs on the open market or distributes the outputs to the farmers in the network
Minimal monetary investment in compost bin construction or purchase
Labor time required to "feed" and monitor the compost basin
Sale of larvae to the refiner
To induce the farmer to sell larvae, the price that the refiner offers must be greater than the value of the unrefined larvae
Distributed larvae production
Costs for the refiner
Purchase of larvae
Sale of outputs:
Refined animal feed - high protein, low fat
Compost and fertilizer
Monitoring the compost bin
Material cost of the compost bin
Labor and materials
What is the break-even level of production?
The outputs from black soldier fly composting are worth more than the input (fresh manure).
Keys to economic success in a small-scale operation:
Minimize the amount of labor required to feed the compost bin.
Maximize the conversion rate from waste to larvae.
Factors that would increase the economic attractiveness of black soldier fly composting:
An increase in the prices of outputs: feed, fuel, and fertilizer.
An increase in waste disposal costs.
Total value of $187 - $347, depending upon larvae conversion rates and the end use of the feed.
Which is much more than a ton of manure!
