Abstract

Among the various types of agricultural waste, significant amounts of energy can be obtained from woodchips derived from comminuted pruning residues. This study aimed to assess the feasibility of using kiwi orchard clear-cut biomass for energy production. The field trial was conducted in a commercial kiwi (Actinidia chinensis) orchard located in Northwest Italy. We evaluated the biomass yield, woodchip quality, energy consumption, and economic sustainability of this practice. Processed data determined the available biomass to be 20.6 tonnes dry matter ha1. Woodchip analysis showed a biomass moisture content of 53% and a relatively low heating value of about 7.5 MJ·kg1. Furthermore, the average ash content was 2.4%. Production cost was 99.6 €·t1 dry matter, which was slightly less than the market price of 100 €·t1 dry matter for woodchips. In summary, kiwi clear-cut recovered biomass may be a valid alternative biomass source. View Full-Text
