  • 100% use of renewable energy sources: hydraulic and solar, thanks to the 30,000 m2 of photovoltaic panels on the roof of Palexpo. Palexpo is the second largest solar power plant in the country. This installation currently covers the equivalent of the annual needs of 1,350 households.
  • Biomethanization of food scraps, the biogas of which is used to fuel the truck that comes to collect the waste.
  • Offer reCIRCLE reusable food containers


  • 75% of the waste is recycled. The remaining 25% is incinerated and used for the city’s district heating system, which benefits Palexpo
  • 50% of waste is recycled and sorted on site, the rest is processed by an external partner
  • The exhibition carpet offered to our clients is 100% recyclable

Future goals

  • Become an energy-neutral building by 2030, doubling the solar power plant and saving 1 Gwh of annual consumption through structural improvements.
  • Join the SIG GeniLac network by 2030 for remote cooling of the building using lake water.
  • Achieving Net Zero Carbon by 2050: Palexpo has signed the commitment of The Global Association of the Exhibition Industry.
