Assessment of pine wood biomass wastes valorization by pyrolysis with focus on fast pyrolysis biochar production

• The valorization potential of two pine wood wastes by pyrolysis was evaluated. • The PPC recorded higher biochar yield (30.54%) as compared to PHC (30.15%). • Average estimates of E α were higher for PPC compared to PHC for KAS, Starink and Friedman. • Fast pyrolysis in spouted bed reactor produced high quality biochars from pine wood. • The suitability of produced biochars for further energy valorization was confirmed.
