Orvieto Plant

The main activities carried out at the plant include sorting and recycling urban waste, anaerobic digestion and quality composting of recycled urban waste and disposal of non-dangerous special waste in landfills . The main objectives, in line with all applicable regulations, are to increase the amount of recycled materials and energy and reduce the amount of waste in landfills. 

Additionally, in Orvieto there are two energy plants powered by biogas produced by the anaerobic section of the waste treatment plant and by landfills.
In 2019, the plant’s intake of waste was 99,910 tons. Of which 44% was sent to the anaerobic digestion and composting section of the plant to be processed and produce quality compost and electricity, while the rest, approximately 56,700 tons of waste, was disposed of in 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 2019, the amount of energy produced was as follows: 
- the waste treatment plant produced 3.3 Mm3 of biogas and 6.7 GWh of electricity;
- the landfill produced 7.9 Mm3 of biogas and 13.1 GWh of electricity

The plant transferred more than 18.6 Gwh energy to the electricity grid.

In Orvieto, energy from renewable sources is also produced by a photo-voltaic plant, owned by Acea Produzione, which in 2019 produced approximately 390 MWh of energy used to cover part of the plant’s energy needs.

Plants for the environment and water treatment

We are actively involved in the design and construction of plants for the environment and water treatment, in collaboration with Simam (Environmental and Industrial Management Services), a leading company in the design, building and management of water treatment and waste disposal plants,
for environment and rehabilitation interventions, with high-tech integrated solutions.
