Generation of Biogas energy from animal waste for use in rural areas by asigealex

@carbonsink,my idea is to raise the forest cover by advocating for an alternative source of woodfuel. So in the long run carbon finance model will automatically set in

Why exclude human waste and insist only on animal waste !! The human excreta could also be a good source of both manure and biogas, so as well the kitchen waste. However, spare the fruit-seeds and don't consider it as waste. They could be used better, a proposal suggests this; link to it is below- https://www.climatecolab.org/web/guest/plans/-/plans/contestId/1300103/planId/1310401 kindly utilize the idea integrating it with your effort. Thanks..

Moreover, people these days are talking quite enthusiastically about Human Fecal Transplant !!

Using animal waste is suitable in this scenario because of the following; The population density of most rural areas in Kenya and the East African region is not sufficient enough to yield adequate human waste for gas generation. Also the settlement pattern in such areas is scattered hence the difficulty in collecting the waste. I therefore strongly support for the utilization of human waste at trading centers, urban areas and other places with substantive population so as to be sure with the requisite amount of waste able to generate gas.

Who is more healthy ! Human beings or animals ! Kindly go through the following and oblige. https://www.climatecolab.org/web/guest/plans/-/plans/contestId/1300206/planId/1002

@Waghhm,thank you for the reference, its quite resourceful. Keep sharing your views

Hey guys after a consideration of incorporating human waste in the proposal, the following technical challenges came about; 1. The Kenya National Domestic Biogas Program, (KENDBIP) launched in 2009 had a four year objective of empowering local farmers who rear livestock to be able to harness biogas energy from livestock waste only. 2. Currently, Kenya National Farmers’ Federation (KENAFF)is the entity that coordinates domestic biogas programs in the country and as such they are currently not having any plans of harnessing biogas energy from human waste. (They haven't introduced the program) 3. Harnessing of biogas energy from animal waste in Kenya currently is being undertaken by individual proprietors and some entities within the private sector and therefore there isn't any national program to coordinate the activity. I therefore need you guys to float in suggestions on how to go about it because my initial plan had targeted rural communities that are mostly livestock rearing.

Not a bad idea

@waghhm, thanks

Hi, This proposal looks great. The idea of 50:50 contribution to the cost of installing a biogas production system is good from the perspective of sustainability. One of the challenges from similar projects implemented in a country like Uganda is how to continuously get animal manure for feeding the system. You may want to consider how to overcome this bottleneck in your proposal. Also, you can have a look at the following link: http://www.afri-flame.net/ Best wishes, Olaniyan MIT catalyst

Kindly go through the following plan and try to use it in your efforts... It would help common people.. https://www.climatecolab.org/web/guest/plans/-/plans/contestId/1301416/planId/1310401

This is a fantastic proposal because it solves a problem with a positive using only a simple natural process. Leveraging animal waste keeps it simpler, I response to previous commenters who asked about human waste, I have seen human waste used as a composting product but feel the human waste would be better isolated from these energy biogas digesters. One symbiosis to the digester network I can imagine would be incorporating some aspect of soil regeneration. (For example, the "rhyzobially based extracellular poly saccharides carbon sequestration" discussed in this proposal. https://www.climatecolab.org/web/guest/plans/-/plans/contestId/1302401/planId/1321402 Imagine a network of energy production bio digesters connected with grazing land that incorporates sophisticated carbon sequestration. This is of course a natural solution to a problem caused by humans. One question I have relates to water requirements for the systemes to work. Will water be available? Can it be harvested from the air as part of the project?

About 75% of the households in the study area rare livestock, this promises a continued potential of biogas generation for the foreseen future.

can someone brief me on carbon finance... and how in relation to sustainable energy

@grahamk Empirical evidence suggests that fixed dome digesters built with concrete are permanent structures that can last for up to 30 years. You can get the research findings at:

Thank you..

Hi asigealex,

The links you listed above are not working.

As Practical Action have none nothing with biogas for many years that does not surprise me!

None of the NGOs want to admit there is a problem!!

I have been researching biogas for some time and have uncovered the fact that though many dome digesters have been built few work after a few months! Do have a look at:

Here is the summary:

Global concerns of climate change, increased greenhouse gas emissions and security of energy supply have accelerated the search for alternative energy sources both in developed and developing countries. Developing countries are now embracing utilization of biogas as a renewable energy option to meet some of their cooking and lighting needs. In Uganda, despite the introduction of biogas in the 1950’s, the technology has not received considerable acceptance and as a result its penetration has remained relatively low. Several installed biogas plants have failed and those working are not working to the expectation of the technicians and their owners. This research presents results of the study carried out to establish the performance of farm based biogas systems so as to assess the challenges faced by the users and to identify the possible causes of failure for the non-operational systems. A survey of 144 biogas plants was carried out after which performance monitoring of selected digesters in the districts of Luwero, Kampala, Wakiso, Mbale, Jinja and Mukono. It was found that 55% of the surveyed biogas plants were not operational and others not performing to the users expectations. Most of the plants monitored were operating in the temperature range of 18°C-25°C with the gas quality ranging between 50-60% methane. Most digesters showed evidence of high organic loading rates indicated by traces of biogas at the expansion chamber. The identified causes of failure were poor system maintenance, poor workmanship during construction works, poor operation practices, availability of other cheap fuel alternatives, laziness and lack of interest amongst the users, lack of alternative sources of feedstock and system blockages. Furthermore, there is need to sensitize people on the need for using alternative sources of energy such as biogas and improved cooking stoves for fuel saving as most of them use wood and charcoal as supplementary fuels. This would reduce global warming through reduced deforestation and bring about environmental sustainability as a whole.
