The drum kiln charcoal maker

 At the Forestry Products Research and Development Office of the Department of Science and Technology, there is a prototype of a drum kiln charcoal maker. I am interested in this item because I feel that we have a lot of biomass which can be used as fuel even just for home use. In particular, I think if we can utilize the discarded shell of  young fresh coconuts after their meat and juice have been extracted, then we can greatly reduce our energy bill spent for cooking.

The problem with charcoal making is that it produces a lot of smoke and so one requirement to make it is that it should be in a far away area where there are not too many people. Another thing I learned from my interview with the DOST scientist responsible for developing the charcoal maker is that biomass charcoal should still be processed into compact briquest in order to maximize their heating value.
