The study determined the performance of small-scale commercial firewood processing operations under the typicalwork conditions of Southern Europe. In particular, five unitswere tested, fedwith the same 2.1-mlong beech (Fagus sylvatica L.) logs. Allmachineswere testedwith sorted and unsorted logs. Productivity varied between 1.1 and 2.1 t h-1, and cost between 20 and 39 â‚¬ t-1. There were significant differences between machines, which may partly be attributed to operator effect. Feeding the machines with sorted logs had a significant effect on the productivity of all machines on test, increasing productivity by 40% and reducing cost by 34%. Fuel use varied between 1.3 and 2.8 l t-1. The energy balance was always very favorable. The ration between output and input was never smaller than 59 to 1 and peaked at 130 to 1. In otherwords, processing required about 1% of the energy contained in the firewood - or 1.7% in the worst case. The productivity figures reported in this experiment were much lower than reported for Northern Europe, which seems to confirm the significant effect of regional work conditions - especially different wood species - on firewood processing performance.
