I went to the chemistry lab today to put the coconut shells into the oven. The shells must be heated at 110 degree Celcius for 48 hours until they become charcoals. Then, I'll have to blend the charcoal into powder. After that, proximate analysis will follow. How Imma gonna do proximate analysis? I still don't know and I gotta ask someone. Wuhuhu.
