After a bit of research, I found out that these sticks are made out of rice husks and other types of waste like saw dust or even engine oil. These materials are compressed and heat treated in a sawdust briquette extruder. There is even a video about this process: Bangladesh Cooking Fuel From Rice Hulls: An Integrated Food-Energy, presented by Compatible Technology International.
CTI also has a page about this project: Biofuel from Ag-Waste heals the Earth & Bangladesh . Congratulations! I'm impressed with their work too.
Even though the sawdust briquette extruder seems to be quite expensive I hope that this bio-fuel will become afordable and replace the non-ecological use of dung as fuel.
Apologies for posting a blog about dung, but to me not putting the dung back into the soil is s sign of great poverty and it made me rather concerned to see it. The soil needs feeding in order to maintain its fertility.
