The cheese factory suspected to pollute the Isere for years. Located in Saint-Just-de-Claix, in Isère, the cheese factory is prosecuted before the criminal court, with its former and current leaders, for "throwing or abandoning waste in the surface water" and "exploitation of a harmful installation water or aquatic environment not in accordance with a formal notice ", as well as for the contravention of" operation of a classified installation without respecting the measures prescribed by decree for the protection of the environment ".

The equivalent of wastewater from a city of 8,000 to 10,000 inhabitants. L'Étoile du Vercors, created in 1942 and bought by Lactalis in 2011, says transforming between 46,000 and 58,000 liters of milk per day on average, up to 100,000 liters during peak periods. It employs 147 people and works with 70 milk producers. A company that manufactures, matures and sells cheese (Saint-Marcellin, Saint-Félicien, goat cheese), it has since its creation rejected its untreated industrial wastewater directly in the Isère. This represents the equivalent of the wastewater of a city of 8.000 to 10.000 inhabitants daily, but in "very fat" according to Sylvain Traynard, DDT Isère (Departmental Direction of the territories), and with "products of disinfection".

In 2000, the company asked for its connection to the treatment plant of the community of communes under construction, before wishing in 2014 to build its own station. What it had refused him four times. A position "incomprehensible and inadmissible", according to Lactalis.
