Owned by four Vaud waste associations, Tridel SA burns the rubbish of half a million people in a single two-line plant that receives its waste through a 3.8 kilometre rail tunnel and sends heat and power to Lausanne through an underground gallery.
Key Takeaways
- Tridel SA operates a Waste-to-Energy plant in Lausanne, owned by four regional waste associations, serving half a million people.
- In 2025, the plant handled 183,423 tonnes of waste but experienced reduced energy sales and profits due to an unplanned shutdown.
- Revenue dipped by 2.3% to CHF 40.252 million, influenced by lower heat and electricity sales after a line outage.
