Remote Sensing and GIS-Based Assessment of Vineyard Pruning Residues for Bioenergy and Biochar Production

Biochar may offer significant soil benefits especially when derived from pyrolysis, a key biomass conversion technique that transforms lignocellulosic residues into biochar, bio-oil, and synthetic gas, contributing to renewable energy resources. Since the wine industry produces relevant amounts of vineyard residues, usually treated as waste, the research explores the potential of utilizing vineyard pruning biomass through pyrolysis processes for biochar production and energy generation in two pilot sites, specifically in Italy and Greece. Remote sensing and GIS mapping are employed to assess biomass availability and potential. The results reveal that neither of the two pilot sites can meet biochar demand using only vineyard prunings as a biomass source. However, fast pyrolysis has proven effective for energy production in both case studies. Regarding TEAPOTS pyrolysis process, it has emerged as an efficient and promising solution to achieve energy and biochar requirements, highlighting its potential for sustainable agricultural practices in the wine sector.
