The European Commission is taking Slovenia to Court for its failure to comply with the requirements of EU waste legislation. The Commission's concerns relate to two illegal landfills containing hazardous waste, one near the centre of Celje, and another nearby Bukovzlak. The case concerns large quantities of polluted soil originating at a 17-hectare contaminated brownfield site in Cinkarna, Celje, Slovenia's third largest town. High levels of toxic heavy metals have been detected at both sites. This infringement concerns breaches of the Waste Framework Directive and the Landfill Directive.
