Global Experiences on Waste Processing with Black Soldier Fly (Hermetia illucens): From Technology to Business

From this website:
www.iwmi.cgiar.org/2019/11/global-experi...hnology-to-business/

Black soldier fly colonies can produce about 100 times more protein per year than chicken or soybeans, not to mention cattle, on the same area of land. The flies can directly feed on different types of organic wastes, leapfrogging closed loop processes within a circular food economy. Also, where no protein is needed, for example, to feed fish or pigs, the larvae can be processed into high-quality biodiesel. However, can this be done at scale? The answer is ‘Yes’. The report showcases some of the leading global businesses in Black Soldier Fly production.

Re: Global Experiences on Waste Processing with Black Soldier Fly (Hermetia illucens): From Technology to Business

Dear Mohammad,
thanks very much for your input. I used soldier flies larvae as fish feed already (Tilapia) and think it is important to do some more research on it. F.e. the protein content of 20% is to low for young fish so they are more suitable for mature fish.

But the statement: "...can produce about 100 times more protein per year than chicken or soybeans, not to mention cattle, on the same area of land..." is simply wrong. Soldier flies can't produce a gram of protein if there is no organic material (waste). And all organic material is produced by plants (or algae). The flies can substitute chicken, pigs, cows and even fish... but definitely not plants like soybeans (legume).

To feed the world we have to intensify and optimise plant production....AND close the loop behind in a very efficient way. And here is a lot to do for the flies!

Have a nice day,
Heiner

Re: Global Experiences on Waste Processing with Black Soldier Fly (Hermetia illucens): From Technology to Business

Hello ,

I am also working on organic waste processing and presently trying out composting using different microbial cultures, however recently came across , Black Soldier Fly, just curious to know how feasible is this for large quantity of waste.like 10 tons per day.. and where i can see this in India,

Thanks
saroj

Re: Global Experiences on Waste Processing with Black Soldier Fly (Hermetia illucens): From Technology to Business

Dear Mohammad,
Thanks for your post, highlighting this new report (please always indicate if text is your own or if it's taken from another website; I have now changed your post so that it's clear that the text is not yours but copied from that website).

Heiner:
Thanks for your insightful commennts. I will contact the authors of the report to get a clarification on this misleading statement (I couldn't find the statement in the report but only on their website; I guess it was meant as an "attention seeker"... but it should still be correct. Thanks for pointing that out.

Saroj:
The report doesn't include examples in India. I used our SuSanA resources to see if I can help you: I checked in the SuSanA library for keyword "BSF" and found only these 7 entries: www.susana.org/en/knowledge-hub/resource...title=&author=&year=
We also have this sub-category on BSF here on the forum: forum.susana.org/147-production-of-insec...eta-or-organic-waste
In there I found a guide from EAWAG ( www.eawag.ch/fileadmin/Domain1/Abteilung...te_Processing_LR.pdf ) but again nothing about India.

Then I had a look at the SuSanA project database, filtering for BSF as a "reuse product" and found these 8 projects:
www.susana.org/en/knowledge-hub/projects...1%5B663%5D=663&test=

There was a project funded by the Gates Foundation in India which made a sub-grant on BSF research:
www.susana.org/en/knowledge-hub/projects/database/details/204

See here: forum.susana.org/forum/categories/147-pr...man-feces-research-p
It was at Indian Institute of Technology Roorkee.

Perhaps you could follow up with them. Their last post was from 2015:

As requested by Elisabeth, here is an update. There is nothing exciting to share with at this moment! We had an unusually long cold winter. The fund was released in January 2015. We are still working on to get used to the rearing of the fly and its larvae so that we can build a community of flies from where we get a continuous supply of eggs and larvae for further experiment. Once we get a continuous supply of young larvae, and other equipment are in place to conduct a scientific work, we will start working with human feces. Right now the larvae are being fed with food waste. We hope to let you know something exciting by August 2015.

Hope this helps,
Elisabeth

Re: Global Experiences on Waste Processing with Black Soldier Fly (Hermetia illucens): From Technology to Business

Dear Heiner,
Thanks for your feedback and contributions. It is obvious that there are things that still need to be done to ensure that we ultimately harness the most of the potential created by the black soldier flies and their larvaes.
On the particular statement that you question (an excerpt of a communication note, not directly in the report), it is important to note that the statement refers to the area of land used to produce different protein sources, and not so much to the method of production of these proteins.

In the report, we have presented what the footprint of existing BSF plants, which could be typically 40m2 per tonne daily input of waste. The yield of larvae is often reported to be up to 118 kg dry weight per tonne of waste processed, with a protein content of 35 to 44% dry weight. It becomes possible to calculate the yield of proteins and compare it to what is seen in other sectors (e.g. one chicken needs 0.2 to 1m2 and will grow about ~3-4 kg (wet weight) in 3 months). By doing so, one notes that the land productivity with BSF is way higher (i.e. can attain 100 times the one for poultry), and this is the message we were trying to convey in simple terms that non-technical people would understand after reading the communication brief. But the report itself remains technical and addressed to a technical audience.

Best,
Josiane.
