Analysis of energetic performance of vine biomass residues as an alternative fuel for Chilean wine industry
The chip pruning of five different vine-producing wines was physically characterized, and its energetic value was analyzed (calorific value and ashes content principally). The material with a better energy performance was established. TCO2 emissions of this wood biomass were compared with the pine pellet, which is the most currently used solid biofuel in this industry. In both cases, the material obtaining process was studied, along with the fuel production and transport required measured in TCO2 emitted per tons. This process was done in order to replace the pellets used in the boilers of the vineyards for the chip pruning of the studied vines. The use of chips as solid biofuel inside the vineyard produces a lower TCO2 emissions than the use of pellets (0.01 and 0.484 TCO2, respectively) because less energy is needed for its production and transportation. This resulted in a decrease in the carbon footprint of the analyzed vineyard. The cost of using this chip instead of the pellets inside the vineyard was also calculated, with an annual savings in vineyard fuel requirements of US$ 23,142 from not purchasing pellets while the annual savings of using ashes instead of industrial fertilizer (CaO) is US$ 450.
