In Orvieto there are two power plants fueled by the biogas produced by the anaerobic section of the treatment facility and the biogas produced by the landfill, which handled over 91,000 tonnes of waste in 2018 alone.

The main activities carried out in the plant regard the selection and management of waste, composting and landfill storage, with two aims: to increase the recovery of materials and to reduce conferrals to landfills.

Biogas production for use in the electricity production chain is one of the key activities carried out in the Orvieto plant. It is a complex process that we will attempt to simplify in these steps.

  1. Waste entering the plant is sorted to ensure the greatest possible recovery of materials.
  2. The sorted waste is then transferred to the conduct lots, where it undergoes two further processes: compacting and covering with clay.
  3. In these conditions, the waste degradation process generates biogas.
  4. The biogas is completely captured and used for the production of electricity.
  5. The energy produced from the combustion of the biogas is released to the electricity distribution network.

In 2018, the Orvieto plant produced 10.2 mcm biogas of which 2.5 mcm biogas from anaerobic treatment.

The plant transferred more than 17 Gwh energy to the electricity grid.

Again in Orvieto, energy is also produced from renewable sources thanks to a photovoltaic plant, which in 2017 produced approximately 450 MWh energy totally used (99.99%) toenergy totally used (99.99%) to cover the plant’s own energy consumption.
