Who: Universiy of Lausanne, founded in 1537

Context: Since April 1, 2009, all waste food produced in restaurants and cafeterias at UNIL are taken to the Saugealles Farm to produce biogas. Clean and economical approach!

Description: Thanks to an agreement between the University of Lausanne and Lausanne Service Sanitation, waste food on campus is now used to make biogas. This gas is then burned in a plant that produces green electricity for about 100 households in Lausanne.

Previously, the food waste was used to feed pigs and coffee grounds were incinerated. These solutions were expensive and were environmentally questionable. The installation of biogas production is environmentally friendly and reduces the cost of waste disposal.

Results: By doing so, University of Lausanne is responding to the global needs for more sustainable waste management. Creating the loops of resources that are reused or recycled is simply addressing the challenge of growing population and diminishing availability of natural resources. So called circular economy is currently evolving into a new global paradigm and more and more companies, organizations and local communities are ready to face this challenge.

Project start: April 2009
Cost: 900,000 Francs (the installation of the biogaz plant)
