Descripción
This paper aims to investigate if the legislation will allow the production of energy from
winery by-products and how this can contribute to multifunctionality of the wine makers’
income. A medium size winery was selected and an anaerobic digestor process was
simulated using the company’s data. The main methods of financial evaluation were
studied to create information to see if the project concepts were valid. The results
highlight the positive level of earnings that the project will generate due to the high level
of methane included in the pressings that could be transformed in energy, the short period
needed for obtaining methane and the recent substantial level of government support both
in Green Certificates and financing of the initial cost of the investments.
