In March 2011 we started our first batch of charcoal at Beer-Sheba. It has been a very interesting process for myself to be involved with because to me I have never really thought much about the process. Charcoal was just one of those things you buy beside the road for your barbeque. What surprised me most is the amount of work required to turn wood into charcoal. (Read more about the science on Wikipedia.)
During the first week of March, I spent 3 mornings in the bush with the chainsaw pruning and trimming trees. Many of the acacia trees have 2 to 3 trunks coming from the base so we cut the extras off, along with the bigger branches at the bottom, and voila, we have wood to put in the charcoal pile and a nice looking tree that will continue to grow! The goal was to attain 20 steres of cut wood in 1m lengths. (1 stere = 1m x 1m x 1m) The target we were told was to cut about 75 medium acacia trees to meet this requirement. I cut down just over 100 and as we found out there is some ‘interpertation’ into what is classified as medium. With the trees we cut down we ended with 17 steres.
After I had cut the trees down and fought my way through the thorns to cut the remaining bigger branches into 1m lengths, our guys Gabby and Mbounda finished off the tedious work of cleaning and cutting the remaining branches with their machetes.
Next was the process of bringing all the wood out of the bush and piling it where we would construct our first pile (meule). Fortunately for us, the wonderful young men and women from the Faylar church once again came out to help us. Without their help we would have had to hire 10 guys for 4 days to do what they did in one day. With the 40 young adults that came out we had all the wood out of the bush and stacked neatly by about 3pm!!! Amazing the power of numbers and we are so grateful for those who come and volunteer their time for this project. As is custumary, we had a big meal prepared for all at the end of the day.
A few guys stayed on the following days for some more formal training using the charcoal production technique we are using at Beer-Sheba. We are using a method that was developed in the Southern Senegal region of Casamance. It is nearly 30% more efficient in the amount of charcoal produced using the same amount of wood! Obviously this fits nicely into what we are trying to do with our forestry management program and we had a very knowledgeable expert from the Casamance come up and do the training for us this past week.
