Illegal dumping in Dublin's north inner city is caused by "bad citizens" rather than poverty according to a city council executive.

Dublin City Council intends to extend its policy of putting up CCTV images of illegal dumping despite queries from the Data Protection Commissioner.

A meeting of the council's Environment Committee heard that 54% of households in the north city are non-compliant with waste regulations.

Executive Manager Declan Wallace said he did not believe that rates of illegal dumping corresponded to poorer areas and said it was a problem of "bad citizens".

He referred to people dumping couches, being willing to buy a new couch but not to have the old one "lifted".

Mr Wallace said illegal dumping was a particular problem in the private rental sector.

Assistant area manager Eileen Gleeson said that the council is in discussions with the Data Protection Commissioner, who has queried the use of posters containing CCTV images of people dumping illegally.

But the meeting heard that it is intended to extend the initiative to other black spots. "It is not intended to publicly shame people, it is to give out the message that dumping is illegal," said Ms Gleeson.

She said council workers had called to 4,700 addresses between February and March and asked householders to show evidence of how they disposed of waste as required by law but only 46% had done this.

The poster containing images of people dumping was put up at a location off Killarney Street where all other efforts at deterrence had failed including the installation of CCTV camera.

Sinn Féin Councillor Ciaran O'Moore said illegal dumping is a crime and asked if people whose CCTV images were used on Crimeline were allowed to complain.

Anti-Austerity Alliance Councillor Michael O'Brien said it was objectionable to label an area as having bad citizens, he said there was an "economic push factor" in illegal dumping especially among people who have lost waivers.
