Values for AC of all samples were found to be in an acceptable range regarding combustion issues. However, the high VM for samples must be considered due to possible rapid combustion which might be difficult to control. As a result, special attention should be devoted to burner design. On the other hand, elemental concentrations were found to fall within acceptable ranges given in the literature [13], except for nitrogen levels of all peel and seed samples, which exceeded the threshold of 0.6 wt.% db, after which emissions of nitrogen oxides become a problem
