Walter Stahel has been the founder and director of the Product-Life Institute (Switzerland) since 1983, the oldest consultancy in Europe devoted to developing sustainable strategies and policies. From 1986 to 2014, he was also director of risk management research at the Geneva Association.

Currently, Walter Stahel works as an author, keynote speaker and storyteller. He promotes understanding of the structure of an economy in loops and its drivers and obstacles (circular industrial economy), spreads knowledge about the competitiveness of a performance economy selling goods and molecules as a service, and identifies the levers to speed up the shift from a linear industrial economy managing flows to a circular economy managing stocks. He does this through workshops, lectures and policy groups.

Municipal Waste Europe is the European umbrella association representing public responsibility for waste.

The members are national public waste associations and similar national or regional associations. They are committed to sustainable waste management that minimises the impact of waste on the environment and promotes resource efficiency, taking into account local conditions. Municipal Waste Europe promotes the interests of its members at European level, through joint positions on waste management issues and legislation and keeps its members informed on the latest EU policy developments. The association encourages the sharing of information among its members, including the exchange of good practice in the local management of waste.

Waste management services are a crucial aspect of the social responsibility for the environment and public health in Europe. This service, including collection and treatment systems, is best developed at national, regional and local level. For these reasons and also for the reason of continuity in the delivery of this indispensable service, regardless of market forces, Municipal Waste Europe promotes waste management as a service of general interest.
