"The improper disposal of waste is a major concern as it deteriorates the living environment of residents," said the department. Waste which is not properly sorted also leads to more landfills, the department added, "which imposes a burden on future generations. Therefore, we consider waste sorting to be very important." Last year, Fukushima reported over 9,000 cases of non-compliant rubbish. Instead of collecting rubbish that does not comply with disposal rules, workers usually paste stickers on the bags informing residents of the violation. Residents would then have to take them back inside, re-sort them and hope they get it right the next time collectors come around. Under Fukushima's new rules, if the rubbish remains unsorted for a week, city workers can go through it and try to identify the offenders via items such as mail. The violators will be issued a verbal warning, followed by a written advisory, before the last resort: publishing their names on the government website. Amid privacy concerns, Fukushima authorities said the rubbish inspection would be done privately.
