Energy potential of vine shoots in La Rioja (Spain) and their dependence on several viticultural factors

Each year, viticulture generates thousands of tons of vine shoots in the Spanish La Rioja region without an adequate system for their use. This study attempts to increase the value of this residual biomass, mainly for energy generation. To this end, a representative sampling of vine varieties and vi...
