Solid wastes comprise all the wastes arising from human and animal activities that are normally solid and that are discarded as useless or unwanted. The term solid waste as used in this text is all-inclusive, encompassing the heterogeneous mass of throwaways from the urban community as well as the more homogeneous accumulation of agricultural, industrial, and mineral wastes. This book is focused on the urban setting, where the accumulation of solid wastes is a direct consequence of life

The most important question to be addressed when designing a criminal justice information system is at whom is the information system aiming and who can and should be reached. When employing the Internet for such a criminal justice information is envisaged, it also has to be discussed which forms of crime should be combated by employing Internet technology. The analysis of who needs support, who can offer information, and
