埋立後約23年経過した都市ごみの物理化学的特性と安定度の研究

抄録

A detailed physico-chemical characteristics of 23 years old municipal solid waste disposed of in a landfill was investigated. The results are compared with other investigations and degree of stabilization of about 20 years old landfilled waste is discussed. After about 20 years being disposed of, landfilled waste may be considerably stabilized but a minor fraction of slowly biodegradable organic matter still remains.
