In the food industry, coconut charcoal (not the activated kind) is often used for barbecues instead of normal coal. Even in this domain, it has some benefits compared to normal charcoal: it has a high heat capacity, is smokeless and has a lower ash content (meaning less cleaning afterwards!) As mentioned, another common use for coconut charcoal ...
