Iskorištenje drvne sirovine u promatranim pilanama područja Akure u Nigeriji

This study was carried out to investigate the efficiency of lumber recovery among selected sawmills in Akure metropolis. Measurements were carried out before and after log conversion to estimate the volume of sawn timber and wood residues generated from the selected sawmills. The outcome of the research revealed that 56.08 % of the log input was recovered as sawn timber while 43.92 % was left as wood residues. From the 43.92 % of wood residue, 34.39 % was left as slab while 9.53 % was left as saw dust. This finding showed that the efficiency of these mills was comparably higher than the results from earlier studies. It is believed that the yield could still be improved by channeling the residues in the form of slabs to other valuable products.Istraživanje je provedeno s ciljem da se ustanovi iskorištenje drvne sirovine u odabranim pilanama u području Akure. Mjerenja su provedena prije i nakon obrade trupaca kako bi se utvrdio obujam proizvedenih piljenica i drvnih ostataka u promatranim pilanama. Rezultati istraživanja pokazali su da je iskorištenje trupaca u obliku piljenica 56,08 %, dok je udio drvnih ostataka bio 43,92 %. Od 43,92 % drvnih ostataka 34,39 % su okorci, a 9,53 % je piljevina. Istraživanja su pokazala da je učinkovitost istraživanih pilana veća od rezultata prethodnih studija. Pretpostavlja se da iskorištenje trupaca može biti i veće ako se drvni ostaci u obliku okoraka prerade u određene drvne proizvode koji imaju tržišnu vrijednost
