Abstract(s)
The aim of this study was to quantify and compare the environmental
impact of the heat of grape stalk pellets with that of wood pellets and
other sources, using the Life Cycle Assessment methodology. The study
was carried out using the ISO 14040/44 series standard. The inventory
analysis and, subsequently, the impact analysis were performed using
the software SimaPro8.4.0. The method chosen for this environmental
impact assessment was CML-IA baseline. The results show that heat
from grape stalk pellets is more environmentally friendly than heat
from wood pellets for 7 out of 11 impact categories, including marine
aquatic ecotoxicity, which is considered the most important impact
category. A global reduction of 1.6 × 104 or 1.14 × 106 or 1.9 × 106
tonne of CO2 eq emissions could be achieved if the global potential
production of grape stalk pellets replaced wood pellets or light fuel oil
or hard coal briquettes, respectively, contributing to the achievement
of the EU’s objectives.
