Committee members

Nicolas Walder


National councillor and former mayor of Carouge, Nicolas began his Zero Waste approach after crossing paths with Béa Johnson and Jérémie Pichon, and above all with the Zero Waste team in Geneva, who made his commune the first “Zero Waste” city. The enthusiasm of the people of Carouge convinced him that ZeroWaste Switzerland represented THE solution to accompany the population towards sustainability. Having tested several of ZeroWaste Switzerland’s recommendations for himself, it was only natural for him to commit to this approach to happy sobriety. 

Silke Walleser

Vice President

Silke studied public health, works in the medical technology industry and has long avoided plastic bags. A 3-month trip with her husband and two children in 2019 made her realize the urgency of protecting our planet, and she decided to play a more active role in protecting the environment. In Zero Waste, she found practical advice for herself and her family, and now wants to go further as a member of the ZeroWaste Switzerland committee to promote more responsible consumer behavior throughout Switzerland.

Sylvia Paolone


Sylvia studied law in Strasbourg, Rome and Paris, but finally settled in Lausanne in 2004. After 16 years as a tax specialist with leading international fiduciaries, Sylvia decided to train as a personal development coach and take a step back from the business world in 2022. Since then, she has joined a foundation as head of administration and financial management. Years ago, she questioned the way we eat and live with nature, noticing the difference between her city lifestyle and that of her grandparents, who lived almost self-sufficiently in the Italian mountains. Inspired by her mother, she has always taken an active approach to waste reduction. Wishing to become more involved in the movement, she joined ZeroWaste Switzerland as a member and then as treasurer.
