Abstract—Pyrolysis is explored as a potential cleaner
valorization alternative for waste pine-dust and shavings from
sawmilling activities in Manicaland, Zimbabwe. The
investigation covers the physical and thermochemical
characterization of the raw material, pyrolysis using a fixed
bed reactor at varying temperatures and subsequent
characterization of the products. The ultimate analysis reveals
that Pine has a CHNO composition of 45.76%, 5.54%, 0.039%
and 48.66% respectively. Thermogravimetry results showed
that the residues’ ash, fixed carbon and volatiles matter
composition was 0.83%, 20% and 79.16%. The high heating
value was found to be 17.57 MJ/kg. Pyrolysis runs were carried
out for temperatures of 450, 500, 550 and 600oC. Results
indicate a maximum yield of bio-oil of 45.7% at a temperature
of 500 oC, which agrees with literature. Generally, the gas yield
increased while the char yield decreased with increase in
temperature.
