Description
Summary:The difficulty in disposing of the sludge ash from incinerated biosolids in the large cities of Japan has led to the use of the ash in construction materials. In smaller cities, the biosolids are composted and used on agricultural lands. The final disposal dispositions are reported for liquid sludge, dewatered biosolids, compost, dried biosolids, incinerated ash, and melted slag. Regulations for heavy metals and toxic elements are reported for the agricultural use of biosolids. Heavy metal concentrations are a limiting factor for the agricultural use of biosolids.
