Technology description

In the southern part of the province of Mantua, a management system for managing slurries has been put in place. It starts with the separation of slurries, which is carried out directly on the farm, with the separator already present in the farm or with a separator installed on a mobile vehicle. The material is  sent to biogas plants  to stabilize the slurries,  produce renewable energy and digestate. In this manure chain a new device, the Mobile Slurry-Manure cavitator, have been developed within the life project. The device makes the materials (manure and slurry) more suitable for the use in biogas plants. Users can include anaerobic digestion plants or farms that require organic inputs to maintain soil fertility. The separated solid can also be inserted in the vermicomposting process, which allows to enhance it in the agro-energy supply chain within the biogas digesters in place of the corn shredded. In turn, the outgoing solid digestate can be converted into quality vermicompost, which is in great demand in the fruit and vegetable supply chain, San Lorenzo, creator of this "manure chain", deals with facilitating contact between producers and users, and supports farmers in the technological and bureaucratic aspects.
