Circular Economy

Bonollo, innovative expression of circular economy

Always inspired by the principle of “zero waste” and reuse of resources, we continue to invest to enhance what nature provides us with and minimize the environmental impact of our activities. After the wine is obtained, the producers give the pomace to Bonollo, which distills it, obtaining true sensory masterpieces, the Bonollo house distillates. But the processing does not end there. In a circular economy, the pomace, after obtaining grappa, is again used to obtain valuable by-products.


Calcium tartrate is the salt used to obtain tartaric acid, a valuable substance of natural origin used in enology, the food industry and pharmaceuticals.


Biomass is obtained by grinding dried grape husks. Since these are rich in cellulose and nutritional substances, they are partly used in the animal feed production industry and partly to fuel the company boilers. This provides steam to distil the pomace and heat to dry it, avoiding the use of fossil fuels.


From grape seeds we obtain the edible oil of the same name (“vinacciolo”), which has excellent beneficial properties: not only is it believed to help reduce the amount of cholesterol in the blood, thanks to the omega-6 fatty acids it contains, but it also contributes to the well-being of the cardiovascular system, thanks to multiple antioxidant substances including polyphenols.


Grape seeds are extracted from a portion of the fresh pomace, which are then used by Bonollo to obtain high quality polyphenols.
Rich in antioxidant properties, these are used in the food supplement industry. Recent studies have shown that daily intake of the supplements obtained from them (Ecovitis®) helps to support the regular function of the cardiovascular system and the microcirculation function.


The liquid residues from distillation and the process of obtaining calcium tartrate undergo anaerobic and aerobic digestion – which reduces their organic charge, i.e., polluting potential, to almost zero – and give rise to biogas, which is then processed in a new state-of-the-art plant that is able to transform it into high-quality biomethane. This plant, opened in April 2023, is the first biomethane plant built in Italy in a grappa distillery. Since this is methane gas of non-fossil origin, it is fed into the local gas network, contributing to the decarbonization of consumption. The average annual volumes fed into the gas network correspond to the average consumption of about 3,000 households.
