RE: charcoal briquetting from agri-waste, to add to the list:

There are the pineapple char-waste people
http://www.businessdailyafrica.com/Corporate-News/Thika-based-energy-firm-to-expand-pineapple-briquettes-plant/539550-3072452-f4w79v/index.html
They jus got 100,000usd grant as well to expand.

Quite a few generic NGO types seem to be doing it as well -
http://www.nottingham.ac.uk/etc/news-SIFEKenya.php and
http://www.greenchar.co.ke/ and
https://kopernik.info/project/start-up-charcoal-sales-in-kenya

Some private business like Kencoco who use cocnut waste
http://www.nation.co.ke/business/seedsofgold/Hey-dont-burn-crop-waste-make-briquettes-/2301238-2325288-4vw7lrz/index.html
and https://www.facebook.com/kenyabriquettesdistributors/?fref=ts and
https://www.facebook.com/economicalbriquettes/?fref=ts
Almost all of them seem to be marketed as ''smokeless' and ''zero carbon''
(not sure what that means)

On a seprate note, Dr. Adam, you maybe happy to know that I just heard from
a friend of mine who said he is using your kilns and is very happy with
them (here https://www.facebook.com/economicalbriquettes/?fref=ts).
