Bioenergy and fertilizers from livestock and agriculture farms

Currently the management practices of livestock manure involve the collection and storage in livestock units or the spreading in the fields. The waste include manure generation from pig or poultry livestock farms, cheese whey and olive facilities. The aforementioned practices constitute significant hazards due to the increased smelling and fire causing. Additionally most of the nutrients are lost and the CO2 footprint is high in the areas were such farms are located.
The facility is private and collects locally available farm manure for free. The manure is transported by trucks in the facility and is digested on-site. The produced biogas is utilized in a generator unit, while the digestate is composted and returned to the nearby fields as soil amendment.
The main stakeholders and beneficiaries are owners of the facility (who also own livestock farms and cultivations) and use the vast majority of the generated fertilizer in their cultivations. In addition, neighboring farming facilities are collaborating offering their facilities’ waste to the biogas facility without the obligation of payment. This constitutes a "win-win" situation in the area since farmers are disposing their waste in a sustainable manner and facility operation minimise the local CO2 impact. All aforementioned as well as local population are the beneficiaries. Finally yet importantly, the energy generated by the facility is provided to the national grid (under an agreed cost per kWh).
