Founding of Les Cheneviers

As early as 1898 the Grand Council voted the first credits for a waste treatment plant. The State of Genève built and ran the first Cheneviers plant, on the banks of the Rhône in the municipality of Aire-la-Ville. Put into service in June 1966 at a cost of 37 million francs, it had two furnaces and a capacity of 100'000 tonnes of waste a year.[1][2][6]
