Karlovac County – Biomass Potential• Considerable forest biomass potential: 57% of total
area covered with forests (33,6% private forests and 66,4% state owned managed by national company – Hrvatske šume Ltd. )
• Annual allowable cut 550.000 m3

Karlovac County – Biomass Utilization• Biomass mostly used in households and wood
industry• Total capacity of industrial biomass boilers: 22 MW
(wood residues)• 73% of population uses fuelwood as energy source
for heating (2001) – mostly old and inefficient wood stoves
• Majority of public buildings uses oil as energy source for heating, only 1% uses fuelwood
