Hi Aziz
I am back to the office now.
As shortly chatted this morning, biogas is very popular in Vietnam and several programs and develop agencies have been supporting biogas. The use of biogas mainly for pig manure. I remember when visiting Daklak with Dr Khanh from TNU, cow manures are sold coffee planters for fertilizers and make good money for cow keepers, and the demand for this is very high…
I suggest that this should be extended to comparing different technology efficiency (biogas, composting, biological bed using EM) from different perspectives for instance economy, health, environment….

In reply to Polly Ericksen. Hi Polly, Are you looking for waste from Cattle or pigs and chicken as well?

In reply to Ndama. agree ... let's first get the seed funding.

Thank you all for support and comments.

Here , I tried to be short and more realistic. If there is opportunity the broader objective of this research is actually to consider alternative waste disposal methods of which biogas is one. Others for example include 1. organic manure
2. deep pond
3. Fish feed

And certainly it would need to be linked to the Mazingira team work!

To what extent should this really be something like a ‘waste management’ set of research, not focused on a single technology of biogas? In fact, it would seem that there are – in addition to the questions Polly mentions, some questions around how to better ‘target’ biogas as a solution – it is not a silver bullet! Now I am not sure whether to vote or not – I am supporting the idea of this area of research – but not promotion of one technology per se!!!

Agree the biogas phenomenon needs some serious data collection and analysis! we are hoping to start some on farm trials on the ILRI campus.

In general I like this idea and that is the reason that I clicked yes. Anyhow, being for many years in SE Asia, seeing with my own eyes quite a few of projects supporting Biogas in cattle being struggling following the end of seed funding (Northern Thailand, or Java, Yogyakarta special province) we should extend the research idea to any kind of waste management options available in cattle or pigs (including biogas) and also carefully review success and failures.

I like this idea, but it would be good to include a review of the adoption and impact of this technology in other countries, e.g. Kenya where biogas production is rapidly gaining popularity among smallholder farmers.
