|Abstract in English:|
Agriculture is probably the main biomass producer in Italy, at present, most of this material is burned in open fields or ploughed down into the soil. This because there is no market for this biomass and there are no equipment able to harvest it at low costs. The paper briefly shows the result of an experimentation, aiming at agricultural prunings collection
(from peach, vine grape and olive trees). Several machines were tested (based on on-field chipping and on-field compacting) and proper adjustments were suggested to the manufacturers, in order to keep costs as low as possible. Then the paper reports the result of olive pruning combustion test. The pruning chemical composition and the thermotechnical characteristics are reported. It was pointed out that a biomass commercial boiler can be used without any adaptations with olive pruning as the test reported an efficiency of 67% and emissions in the law range.
