Tohoku region, Japan (CNN) - More than a year and a half after Japan's devastating earthquake and tsunami, there's still more than 13 million tons of debris.

Some debris from near the fukushima nuclear plant is being hauled to other parts of the country, ground up into mulch and burned.

Officials say, the debris has not triggered any elevated radioactive readings. Still, many don't want potentially hazardous materials coming to their towns and cities.

Tsunami debris is Japan's biggest cleanup job since WWII, and officials say the cost may double to an estimated $125 billion.
