Would anyone out there help turn coffee husks into some useful renewable energy source in Karagwe, Tanzania?

Greetings. I am called Joseph Sekiku, working with the Eden Centre for Appropriate Technology (www.ecat-fadeco.org). I am confronted by a desire to find solution to waste that could be turned into useful stuff (energy) here.
Let me explain:
I come from Karagwe district, Kagera region, NW Tanzania. This is a predominantly coffee growing area. Since 4 years ago, with the liberalization of the coffee trade, 6 coffee processing factories have started. Two years ago, two of the factories were destroyed by fire from coffee husks heaped outside the factories. There are now 4 coffee processing factories.
These factories produce a lot of coffee husks (thousands of tons).
Unfortunately, these husks have no commercial value at all. Instead, after the season, they are set on fire. The fire goes on for months.
I believe that these husks can be transformed into some useful energy source - either into electricity or just for cooking. I have been imagining a situation where these coffee husks could be transformed into briquettes, ceiling boards or even mulch for the farms.
Imagine for Karagwe district, there is a very high rate of deforestation- and apparently much of the forest cover is completely no more. Tree cutting continues to today.
I am sending you some pictures about the situation. I have talked to the coffee factory owners : Karagwe marketing Ltd, KDCU Ltd, Amri amir Ltd and another one that I do not have the name off hand now. They have no plan for the thousands of tons of husks from their factories but to set fire on these.
let me know please,
