Make charcoal briquettes from agricultural waste

Demonstration on how to make charcoal briquettes, by Amy Smith of D-Lab, MIT . For more information, please contact [email protected] The charcoal is made from agricultural waste materials using an oil drum. In this case maize stalks were used. The charcoal is compressed to briquettes using a simple hand-operated press. The demonstration was held during the IPIDAT 2009 meeting.

What is astonishing is how simple the process can be. From converting the vegetable material into charcoal in a regular 55-gallon oil drum, to mixing it with a binding agent (cassava paste, in this case), and then using the most elegantly simple tools to churn out perfect little briquettes. It’s like witnessing the invention of the wheel!

The entire process is very straightforward, although a few steps could use some clarification. For example, we were curious to know why the ultra dark smoke following the ignition of the material in the barrel? Or, why did it flame with a single match following the initial internal combustion? Otherwise, the video is very comprehensive in documenting the process.
