As I mentioned elsewhere, at the recent Delhi toilet fair, six awardees were announced of Gates Foundation prize funding including one focussing on black soldier fly larvae (forum.susana.org/forum/categories/139-in...nda-gates-foundation):

Indian Institute of Technology Roorkee in collaboration with Fresh Rooms Life Sciences: The project will develop a single household container that will cultivate Black Soldier Fly larvae, using human faeces, which can be processed into valuable products. The project will also demonstrate the market potential for these products. This is a proof of concept grant.

If I find more details of what they're proposing, I will add it here.

(I have moved the post from a different thread as this one seems more relevant - in case anyone is wondering)

Its a no brainer! BSF larvae devour human faeces!
Don't throw it all away!

I just found this video from the Reinvent the Toilet Fair in Delhi online where at minute 2:31 you will see the Indian researcher (Sudipta Sarka from IIT Roorkee) talk about his planned research on black soldier fly larvae which they will feed on faeces from urine-diverting toilets:



@ Billy: yes, it's a no brainer that black solider fly larvae love human faeces. But the devil is in the detail: how many of the faecal pathogens could end up in or on the fly larvae and how should the fly larvae to be processed to make it into a safe feed for e.g. fish? And what about the pharmaceutical residues in the faeces. And what would be optimum feeding regimes etc. There are still plenty of open research questions here (let along the legal questions, see forum.susana.org/forum/categories/91-pro...d-for-farmed-animals )

Quite right, Elisabeth. I was a bit hasty with my remark. Truth is I am a total newbie on BSF and amazed at the voraciousness of the grubs. Thanks for the link, but it gave a page error - which is a pity because I enjoy studying from this forum. I suppose mature grubs going off to pupate would most probably carry a bit of what they have been eating on their coats...! Perhaps the trick would be to somehow transfer the grubs, whilst they are still hungry, into a feedstock that would purge and cleanse them! I was thinking about using the white meat from green coconuts. You see, here in Rio a lot of green coconut is sold for the water along the beach front. Nowadays the coconuts, for some strange reason, are no longer opened for us to eat the pulp. So the garbage bins hve loads of coconut with no water but with the meaty stuff inside. If I was to get someone to open the coconuts and scrape the insidea I would have a very interesting feedstock... As soon as I get my act together I shall experiment. Meanwhile I have found an abundant supply of larvae in rotten jack fruit and they get fed kitchen scraps and ummm processed food.. Come to think of it, jack fruit would clean the larvae, it has a sticky gum together with the pulp (polpa inPortuguese).. I haven't harvested any mature larvae yet and shall not be popping any directly into my mouth when I do (thanks for the tip)! This is definitely new fontier stuff for the old latrine fly!

Got to where the link would have taken me. I reckon purge and clense with a post faeces feedstock/substrte and then some time in an oven should render the grubs fairly harmless... Sure can't be worse then the antibiotics injected into factory farm animals.
Don't throw it all away!

We have received the following information from Dr. Sudipta Sarkar, who is part of the team at Indian Institute of Technology Roorkee which is a co-collaborator on this project. Dr Sarkar has asked us to post this statement here:

In this proof-of-concept project, we aim to develop and validate a novel waste treatment system where human fecal matter and other bodily waste materials shall be consumed by Black Soldier Fly (BSF) larvae, mature prepupae of which can be harvested to extract valuable products. Specifically, with the award funding we look forward to achieving the following objectives in next one year:
a) kinetics and extent of growth of BSF larvae on different types of substrates (mixed with human faeces) and under different environmental conditions to find out their effect on its life-cycle in and out of the substrates and also on their waste conversion rate.
b) the extent of artificial mating and mass hatching of eggs under different controlled conditions; and,
c) research on the potential market for the valuable by-products that can be produced from the harvested larvae.
Our team at IIT Roorkee shall also work in the future to design and develop better toilets which shall provide high degree of comfort for the users, a feature largely absent in the individual and community toilets in rural India. We believe that if people are provided with a better option such as a good-quality toilet, they would never go for open defecation. To this end, cost of installation and upkeep of high-quality community toilets can be sustained only if they are supported by a sustainable business model where all the stakeholders shall get benefitted. A social enterprise-driven system fits perfectly well here, earning profit from recovering market values from the liquid and solid excreta. The mature BSF larvae are rich sources of fat, protein and chitin, all of which can be processed to make products of high market value. My team at IIT Roorkee shall also perform research on the downstream processing of the harvested BSF larvae for optimum generation of values.

This is a proof-of-concept step, based on which there will be a much larger project leading to prototype development and implementation. BSF larvae are being tried for stabilization of municipal organic/ food waste in many places around the globe. In India, a small firm named Freshrooms Life Sciences located in Chennai is commercially producing chicken and animal feed derived from BSF larvae grown over food waste. In the current project, IIT Roorkee has decided to make the firm their partner.


I am interested in what the 'products of high market value' from the larvae might be.

Joe: Could be the chitin from the exuvia - the empty pupal exoskeleton. BSF larvae go for human excreta like it is going out of fashion, for as long as temperatures are, lets say, above 30C. Unfortunately I found this out by trial and error... In my case, error! Fortunately my experiments are on a me, myself and I basis and outdoors, thus no harm done and the remains of my last contribution have been slowly turned into worm feed as winter temperatures kick in and larvae activity fade out. I am still very enthusiastic about the use of BSF larvae and vermicomposting for organic waste composting and also for fecal management. But for the time being my experiments shall be just with fruit and veg scraps!
