Response to condom experiment on food waste vs dung for biogas

I got a really interesting response from T.C. Culhane to my earlier blog post on my experiment about biogas in which I tested the theory about kitchen waste vs cow dung for methane biogas.

My condom experiment showed that cow dung was far superior to kitchen waste in gas production

Here’s what Culhane had to say

“Marcel Lenormand called my attention to what you are doing.  It is great to see a small-scale experimental design for biogas which can be easily replicated. With my experience building digestors in Kenya as well as Egypt, Tanzania and the U.S. I thought I might share some thoughts.  First, you will not get any appreciable methane from the food waste container and you are right, it will rot and consume the air (this is the sucking the condom into the cup you observed). This is because food waste contains virtually no methanogens if any at all.  We did the same experiment in Cairo with a 200 liter drum filled with food waste to prove it to ourselves, just in case.  One needs a source of methanogenic bacteria, and normally that is from cow or horse or pig dung (others have used goats and cows and I’ve even started a digestors using my baby’s soiled diaper). However once you have enough bacteria producing gas the kitchen waste is a superior food. In all the cases we’ve observed the dung definitely starts producing gas first because the mix of dung and food can turn too acidic, inhibiting methanogen growth. This is why Dr. Karve always recommends you start your digestor with animal dung first and WAIT until you get your first FLAMMABLE methane before adding food waste.  But from then on you need only add food waste. You just have to make sure you do not add too much.  Karve says (and we’ve confirmed) to start feeding slowly, about 200 grams at first and gradually building up to no more than 2 kilos a day for a 1000 liter system.
It may be that what you are observing in your condoms is not methane at all, but CO2, for this is the first gas to be produced.  Over a period of several weeks the CO2 concentration drops to about 40% and the methane concentration increases to about 60% and that is when it starts burning.  So don’t let the gas production you see at first be the indicator of how well your system is doing. What you are trying to do is grow a stable and large colony of methanogenic bacteria.  Once you have done that, you can start feeding the food waste and you will not have to feed animal wastes again (though you are always welcome to — it is a good thing to add fresh bacteria through new dung introductions but if it gets to be a hassle you don’t have to put more in.) Among the Masai at the Boma we recommend putting any waste cabbage leaves and potato skins and ugale that fell on the floor and mix in any cow dung that is convenient. The addition of the food wastes improves output. Hope that helps!”

Well, Mr. Culhane this really helps a lot and though my dung digetser is working fine now,  I do have to go back to the drawing board and re-do the experiment but will need a new supply of condoms for that!

Does kitchen waste produce as much biogas as fresh cow dung?

I am hoping to have a very successful home biogas production system (which I wrote about here)  in about 2 weeks. But what should I feed into my system to make it really successful?

According to Dr. Anand Karve  on the ARTI website 2 kg of carbohydrate rich vegetable feedstock produces about 500 g of methane, and the reaction is completed with 24 hours. While the conventional biogas systems, using cattle dung, uses about 40 kg feedstock to produce the same quantity of methane, and requires about 40 days to complete the reaction. He won an award for this finding.

So should I switch from cow dung to kitchen wastes?  I’m not convinced – maybe Dr. Karve’s Indian cows are less flatulent and produce little biogas – I know that our Kenyan cows are super producers of gas.  But then how can I be sure?

A shitty experiment

To find out whether kitchen waste is better than cow dung, I am conducting an experiment that involved cow dung, plastic cups, condoms, water and kitchen wastes.

I added equal amounts of dung and water and mixed it and poured into a plastic cup, then covered it with a condom to enable me to see the gas forming.

The same amount of kitchen waste was similarly mixed with equal amounts of water and mixed poured into a cup and covered with a condom.

A third experiment involved a mix of dung and mashed kitchen waste, mixed with equal amounts of water, poured into a plastic cup  and covered with a condom. I conducted this experiment in my kitchen using clean disposable utensils and unused condoms (had to say that just in case you people think I’m really weird).

Results

I’ll be posting the results in pictures here

Day 0 (May 25 9 pm)

The condoms are all empty and flaccid. Sad. There was a slight emergency when one of the condoms broke as I was putting it on the cup…  I had to get more condoms purchased at 9 pm. Pharmacist was amused.

Day 2 (May 27th 9 am)

Hmmm, some biogas already being produced and poop looks like it’s slightly more than poop and veg which is more than veg alone. So far I’m putting my money on cow poop.

Day 3 May 28 10.20 pm

Watch this space for coming days and potential explosion of cow poop in my kitchen.

Our wedding is helping Kenya’s IDPs

During a visit to Nakuru recently we dropped in on an IDP camp.

What we saw and heard was infuriating, humbling and down right wrong. The Kenyan Government has abandoned thousands of people who cannot go back to where they came from.

Today we are going back to the IDP camp after we made a promise that we would try to help. On our own a contribution would not have really amounted to much.

So we asked all our friends and guests at our wedding to help – and they have.

We’ve raised a little money which we will take today. Watch this space for photos.

The history of Kenya as told by the former colonialists

According to the BBC, this is a chronology of key events that shaped Kenya:

You’ll notice that they conveniently forget that the Chinese were in Kenya from the 15th Century…

They also don’t mention that over 14,000 Kenyans died during Mau Mau – and less than 100 whites

Kenya first president

Kenya’s first president Jomo Kenyatta (his name means the light of KEnya) wore endangered species skins and carried an ivory walking stick). Like Presidents Moi and Kibaki after him, he showed little concern for the environment and wildlife and left a legacy of destruction. His own direct relatives engaged in the ivory and rhino horn trade leading to the collapse of Kenyas herds. Frankly the British didn’t do much good either – they started the whole concept of killing animals and destroying our forests.   Grrrrr…..

Interestingly the post election violence that rocked Kenya in 2007 elections saw 1,500 killed, vs less well reported 2000 who are reported to have been killed in 1992 elections.

Bombing of the Norfolk Hotel in 1980 is not mentioned

Kenyan journalist-speak

Kenyan journalists must have all trained at the same school of journalism where they earned their MC’s – Master of  Cliches.

President Kibaki and Prime Minister Raila Odinga Yesterday held “closed door meetings” of their parties to “hammer out party positions on new law ahead of negotiations. Meanwhile “heavy rains pound various parts of the country”.

Here are some of our favourite cliches.

Wrongful shootings by police –  “killed in  a shoot out, unclear if he was felled by police bullet or if carjackers shot him”

Exra-judicial police killings of suspects – “Carjacker was gunned down”

Impersonators – “masquerading as a tax official”

Illegal search of suspects house – “Tobacco, pillows, knife and fork, and a kitchen sink were also found in the mans house”

Lobbying –  “angling to get a foothold”

Investigating fraud – “unravel theft”

While cliches allow editors to recycle about 50% of all phrases each day, journalists reserve the best chiches for themselves whenever the Media Act is discussed.

Lets be clear, the new media legislation aims ban on offensive language and glorification of violence. Sounds good no? No? Not according to journalists who go overboard on the issue describing it as  “anti democratic, narrow minded, gagging the media, fundamentally violating the enjoyment of Kenyan citizens,  muzzling the media, and contravening the right to freedom of expression and conscience of, and free press”

I think I love this new law – finally something to stop Caroline Mutoko and gang from gay bashing and spreading homophobic hate and violence.
