Judge Thomas Donnelly issued the order after years of complaints about odors near the animal-feed additive facility at 2701 E. 100th St. The plant must remain closed until at least Jan. 14, 2027, when the court is scheduled to hear the city and state’s request for a preliminary injunction. The shutdown will continue until a final order is issued, according to the order described by Attorney General Kwame Raoul’s office.

Raoul said the plant should not reopen until it addresses odors and air pollution and complies with Illinois environmental law. He said nearby residents have endured environmental harm and odors that disrupted their lives and their ability to enjoy their homes and neighborhood.

Chicago and the state sued Pullman Innovations in August, alleging violations of state and city air-pollution laws. The company makes an additive for animal feed used by farmers who supply eggs to Dutch Farms.

Complaints about the smell predate Pullman Innovations’ ownership and stretch back decades to a previous operator, Agri-Fine. City health inspectors have repeatedly cited Pullman Innovations for code violations, while Illinois Environmental Protection Agency investigators have documented odors inside the plant and in surrounding neighborhoods. Investigators reported that the smell at times made breathing difficult.

In testimony submitted in support of the restraining order, a city inspector said he had conducted 160 inspections at the facility. He described a rotten-egg, sulfur-like odor that burned his nostrils and caused an acute headache.

A lawyer for Pullman Innovations’ parent company, A-F Acquisition LLC, did not immediately respond to a request for comment.
