ABSTRACT
In the present study, two different by-products, pecan shells, and sawdust obtained from
the region of Chania, Crete, Greece, were subjected to slow pyrolysis over a temperature
range of 250–550°C, for the production of biochar. The quality of the produced biochars was
assessed by evaluating their main properties, namely pyrolysis yield, pH, volatile matter
and char content, surface area, and C, H, S, N content. Thermogravimetric analysis, Fourier
