Great model. Would people be less likely to buy gas made from human waste as opposed to slaughterhouse waste? I know technically it is not an issue but is it an issue in public opinion?
There might be potential for collaboration with Issac Durojaiye in the collection of waste. Do you happen to be working in similar areas within Nigeria?
There is no difference between the biogas produced from both human waste and slaughterhouse waste. Production of biogas from slaughterhouse waste is not an issue in public opinion. However, we are conscious that the production of biogas from human waste could be an issue in public opinion from cultural point of view. That is why the biogas produced from human waste under this model would not be commercialized unlike our “Cows to Kilowatts” model. It would not be sold to the public with limited understanding of the production process of biogas. Hence, a significant portion of the biogas produced would be used to generate off-grid electricity through an internal combustion engine for the school. The remaining biogas would be compressed in cylinders and used to cook student meals in the school hostel. The demand for electricity and cooking gas is enormous in Nigeria. Power supply is sporadic and the demand for cooking gas far outweighs the supply. Our revenue would be generated from the school budget for electricity and cooking gas. Our price would be half of the market rate.
To ensure buy-in and product acceptability, an Appreciative Inquiry (AI) Summit would be conducted as part of the project implementation process. The AI Summit would include the stakeholders from the Nigerian Federal and State Ministry of Education, Health and Environment, Principals and School Teachers, Student Leaders, International Donor Agencies (UNICEF, UNEP, UNDP, World Bank, etc), Civil Societies working on health and environment issues and Private Sector participants). The AI Summit would include awareness campaign among other things. This approach was used for our celebrated "Cows to Kilowatts" model and it worked excellently.
Concerning DMT Mobile Toilets, there would be no collection of waste under this model. The waste would be generated on-site by the school children. We are both involved in sanitation but focusing on different issues. We are involved in technology innovation on waste treatment and renewable energy while DMT Mobile Toilets is involved in waste collection. However, we anticipate future collaboration.
Hello Joseph, It's great to see your entry in the competition. Could you tell me more about the stake-holder's workshop? What is the duration of these workshops? How many people are involved? How do you engage the government, the private sector and civil society?
You mention that the biogas plant has the potential to generate significant income. Who will it be generating income for? Approximately how many people will be employed?
Thank you

The stakeholders workshop would be conducted in the form of Appreciative Inquiry (AI) Summit which is an integral part of the project implementation. The AI Summit would include stakeholders from the Nigerian Federal and State Ministry of Education, Health and Environment, Principals and School Teachers, Student Leaders, International Donor Agencies (UNICEF, UNEP, UNDP, World Bank, etc), Civil Societies working on health and environment issues and Private Sector participants). The workshop would last four days and would bring together approximately 500 participants. The AI Summit would include awareness campaign for project buy-in and product acceptability among others. This approach was used for our celebrated "Cows to Kilowatts" model and it has always worked excellently.
Concerning income generation, the income generated would be used to scale-up and replicate the model in other states in Nigeria. Approximately 22 people would be employed during the construction of each biogas plant. However, only 5 people would be employed for the operation and maintenance of each plant after commissioning. Hence, since the pilot would be tested in 10 secondary schools, about 110 people would be employed during the construction phase while 50 people would be employed after the plant commissioning.
Congratulations on what appears to be a very ideal potential. Can this technology be scaled down or is it operational only on the scale you have outlined?
The technology can be scaled down. For instance, our celebrated "Cows to Kilowatts" model converting slaughterhouse waste into renewable energy is 3000 cubic metre while the "hybrid-UASB model" for the schools is 300 cubic metre. Bioreactor could be as small as 1 cubic metre. The sizing of the bioreactor is determined by the pollution load of the waste (COD/BOD5), wastewater volume and available fund also. You could determine the volume of the waste to treat.
Hello Dr. Adelegan,
Simple question - does one need special toilet in order to capture the waste? Have you provided special toilets to the schools in which you have pilot projects?
Thank you.
Dana Frasz
A sanitation system is composed of the toilet and the treatment system. A toilet system could be the pour flush toilet (offset single pit toilet with pour flush, offset double pit toilet with pour flush, Pour-flush toilet with two chamber septic tank with soak-pit, etc), the Ventilated Improved Pit (VIP) latrine, Aqua Privy, etc and the conventional treatment which is the septic tank and soak away system. A special toilet is not required to capture the waste. However, schools with VIP latrine would need to install pour flush toilet.
The conventional treatment system (that is, the septic tank and soak away system) would be replaced by a single unit referred to as the "hybrid Anaerobic Fixed Film (AFF)-Upflow Anaerobic Sludge Blanket Reactor (UASB)". This is the technological innovation. The innovation is not in the toilet, it is in the treatment system that treats the waste with high pollution load reduction and generation of high quality biogas. The toilet is required essentially to discharge the waste through a sewer to the "hybrid AFF-UASB" reactor. A special toilet is not required for the pilot project since the schools already have pour flush toilets installed.
The technology can be commercialised. We have applied the technology at commercial scale to industrial wastes including cassava waste, slaughterhouse waste, friut factory waste and so on. The technology is applicable to any organic wastes including human wastes.

I liked your question, Dana.
Collection of untreated sewage is an issue and its delivery problematic.
best,
Brian
I would like to learn more with a possible site for commercialization...thank you.
