One could easily get the impression perusing the internet that harvesting Black Soldier Fly (BSF) larvae on a commercial scale grown off food scrap waste is akin to spinning straw into gold as in the well-known fairy tale, Rumpelstiltskin, in this case however recovering valuable animal feedstock in the form of high quality protein and lipid-rich larvae. This blog reviews some of the challenging economic issues concerning farming BSF on a commercial scale. ...Read More?
In a series of earlier posts on this website I described varying aspects relating to the management of input waste, the output of spent waste, propagation and seeding steps in replacing harvested larvae, and the general layout and processing of bioreactors stacked vertically atop one another as a means of reducing the footprint of a modular Black Soldier Fly (BSF) plant facility .... This blog goes into more detail on how to calculate the logistical requirements in meeting larval production goals, namely the footprint in bioreactor space required to achieve a planned larval yield, how much input waste must be supplied in supporting a steady output of larvae, and BSF mating and propagation levels needed for seeding waste with new larvae in replacing those harvested, all in keeping the operation running on a sustained basis. ...Read More?

Black Soldier fly (BSF) larvae, on reaching the prepupae stage in their life-cycle, spontaneously self-harvest from waste in search of a dry and dark place to pupate (see The Life Cycle of the Black Soldier Fly).

This blog describes a practical and inexpensive way of screening BSFL and their byproducts for coliform contamination. ...Read more?
The natural arc in the evaluation of a new technology progresses in fits and starts beginning not surprisingly with hype and excitement, moving on to disillusionment, and ultimately adoption or rejection of the technology as a business venture based upon its practicality and viability under real world operating conditions. This blog discusses proposed farming of Black Soldier fly larvae (BSFL) for biofuel production in the context of its practicality as a business venture.
Commercial farming of BSFL (Black Soldier Fly larvae) grown off of food scrap requires accurate record keeping and monitoring for optimal BSF production year round. An important aspect in keeping a colony productive involves culling off a portion of the daily BSF prepupae harvest for maintenance of the insect colony. For optimal year round yields, the emergence of new adult BSF should be monitored on a regular basis in propagating new offspring. ...Read more?
Scaled up commercial farming of BSFL (Black Soldier Fly larvae) grown off of food scrap and/or animal manure could be a big step forward in reducing the dumping of greenhouse gases into the atmosphere associated with recycling wastes, return and restore carbon, nitrogen and other essential plant nutrients back to soils, reduce overfishing of our oceans and, hand in hand, create new business opportunities associated with the construction and operation of BSFL processing plants. While the potential in realizing commercial success exists, there are significant hurdles to be addressed if this goal is to become a reality. ...Read more?
