Radiation-tainted sludge, ash continues to pile up at Yokohama treatment centers


  • Radiation-tainted sludge, ash continues to pile up at Yokohama treatment centers

    The 16,000 cubic meters or so of sludge that is produced at sewage plants in Yokohama each day is divided up equally and processed at the city's northern and southern treatment centers. The southern center previously handed incineration ash over to cement manufacturers, but after businesses stopped collecting the ash in mid-May due to the detection of radioactive materials, ash started piling up at the center.

    As I was photographing workers transferring ash into bags, one worker warned me, "Don't get too close." Since pickups of the ash stopped, each worker has continued to pack 500 kilograms of ash into bags by hand. The fine ash particles rose into the air, making me realize the importance of wearing a mask. Since May, the workers have worn special filter masks.
