Refuse at Shanghai Refuse Landfill was excavated from the compartments closed from 1991 to 2004; and the composition of aged refuse was studied. The results show that plastic and rubber fractions were well preserved from photodegradation and oxygen aging in closed compartments, and can be recycled after simple pretreatment; the content of organic fraction, mainly including plastic fraction, increased logarithmically with placement time and will exceed inorganic fraction after 2010. Thus thermal treatment, such as incineration and hydrolysis, may be an effective way for the cycling of aged refuse.
Keywords:aged refuse; excavation; sorting; recycling
