22.2.4  Disposal of solid waste

Even after recycling and resource recovery there will almost certainly be some residual waste that needs final disposal. Methods of disposal can be sanitary or unsanitary. Open field dumping is the most unsanitary method of refuse disposal and is most likely to cause a health hazard. Sanitary methods – including controlled tipping or controlled burial, incineration and sanitary landfill – are discussed later in this study session.
