Our main sources of energy come from the photovoltaic system built on top of the roofs of each pigsty, and from the biogas system, fed with the residues from the farm and from affiliated cattle sheds.
The biogas heats both specific areas of the farm (for example the weaning departments) and the operating offices of Piggly.
A formula of active microorganisms is sprayed in the stables to eliminate odors, flies, ammonia emissions, and to raise the levels of social sustainability.
From the biogas plant we obtain the digestate that we use as a 100% natural fertilizer on the land, eliminating chemical fertilizers.
