Veliki potencijali energije iz obnovljivih izvora se nalaze u biomasi, a posebno šumskoj biomasi. Pod šumskom biomasom se podrazumijevaju nadzemni dijelovi stabla, a to su: deblo, krošnja sa lišćem/iglicama, kora, sjeme i šišarice. Iako je biomasa, panj se ne koristi u prirodnim šumama.
Bukva (Fagus sylvatica L.) dominira u šumama Bosne i Hercegovine i predstavlja važnu sirovinu u proizvodnji šumskih sortimenata. Nakon sječe, izrade i privlačenja bukovih sortimenata u sječini ostane značajna količina neiskorištene drvne mase, koja je energetski potencijal iz obnovljivih izvora. Zbog toga je cilj ovog rada utvrditi sveukupnu količinu biomase bukve u odjelu 92, odsjek „a“, GJ „Žuća-Ribnica“, ustanoviti količinu šumske biomase (deblovinu koja ostaje iza sječe i grane - drvna masa iznad 7 cm), ustanoviti količinu šumske biomase (drvna masa od 3 do 7 cm) te količinu kore. Istraživanje je provedeno na 60 stabala bukve. Zapremina drveta debla i kore debla utvrđena je metodom sekcioniranja, a masa grana utvrđena je vaganjem. Izjednačene vrijednosti zapremine drveta debla i kore debla pretvorene su u masu suhe tvari .
Na osnovu rezultata istraživanja utvrđeno je da se u odjelu 92, odsjek „a”, GJ „Žuća-Ribnica“ iskoristi 73% (1.605,24 tona) drvne biomase bukve, dok u šumi ostane neiskorišteno 27% (582,59 tona). Što pokazuje da veliki energetski potencijal iz biomase bukve ostaje neiskorišten.
