by use of human wastes,it improves sanitation to the environment. at the same time use of biogas as fuel mitigates climate change

I think we can also borrow this idea to our campus as well to reduce human waste effects to the environment.

This will save our forests as we will get an alternative of fuel.

Biogas sounds as a good technology which can be replicated in many parts of the world to mitigate and enhance climate change adaptations.

Biogas use is environmental friendly and more economical when compared to wood and charcoal use.i t reduces the anticipated environmental pollution.

I have lived where biogas (from pigs) is used. There is a slight odor about it if you stand near the open flame while cooking (perhaps there is a solution for that effect). But, the system is viable, inexpensive and effective. It could be incorporated in several livestock situations where cooking or hating fuel is needed. Nicaragua is one place where this proposal would be of great benefit. Sewage goes directly into several lakes and there is a disastrous forest harvesting practice occurring for cooking.

Proposal

Thanks PJ, i think the proposal will incorporate all the required measures to reduce the odor from this site of the cooking. Literature indicates that, we have proper ways of eliminating the gases which causes the odor; like hydrogen sulphide.As hydrogen sulphide (H2S), a natural component of biogas, is extremely reactive with most metals, kitchen equipment such as stoves and stovepipes are prone to corrosion.It also smell like rotten eggs, which cause the odor. It can be removed by installing a H2S trap (Mottet, 2009): Two columns (one for desulphurization, one for regeneration) filled with iron oxide for absorption of H2S; the H2S reacts with the iron oxide to form iron sulphide and water. Addition of sufficient air converts the iron sulphide back to the oxide and leads to precipitation of elemental sulphur. We can as well use its smell to detect a leakage in the piping.

The stakeholders for the project are clearly defined, and if technology in well defined then the project can be scalable. However, the proposed technology has not been proved to be reliable. The project would require more investment in the future, especially with regards to maintenance.
