Energy
What is BIOGAS?
Biogas is an alternative renewable energy production source. The gaseous biofuel production process is based on oxygen free fermentation (anaerobic digestion) of various agricultural plant biomass and organic residues.
The whole process takes place inside the digesters at a controlled temperature using active microorganisms that convert the raw material into biogas, which consists of 50-70% methane with the remainder made up of CO2 and other components. Biogas produced in this way supplies a cogeneration facility that produces electricity, which is then transferred to the Italian national grid.
The fermentation residue is the digestate, consisting of a liquid part and a solid fraction that is completely odourless and of very high agronomic value; this is used in the fields as a substitute for chemical fertilizers.

Plants and locations
Our Plants
The group’s plants are located in different areas of Central Friuli and have a total power output of 16 million kW/year, which can supply the energy requirements of approximately 7,000 households. Near each plant, there is land set aside for the cultivation of energy crops for biogas production.
GREENWAY
Located in the Bertiolo industrial zone, the plant, with its 1 Megawatt of power, is capable of producing almost 8,000 MW/year. The plant is fed by a supply chain consisting of a group of farms that grow all the biomass required on Greenway-owned land. Depending on the season, between 35 and 30 people work within the energy supply chain configured around the plant’s operations. The plant also produces digestate, an organic material that is used to fertilize ‘producer’ soils and improves their quality. We use plant technology made by Schmack (Germany), a leading company in Europe in the construction of biogas plants.
SAN DANIELE bioenergy
The plant is in a separate location in an area adjacent to the industrial area of San Daniele in a small wood, which in and of itself mitigates the impact of the plant by harmonizing it with its surrounding environment. The agricultural supply chain is the same in every aspect as the Greenway agricultural supply chain in that it is local and complements that of Greenway itself.
