The study of waste from historic cities, disposal systems and practices today has a value that affects environmental history and is no longer limited to the perspectives of historical-documentary study (Laws, Statutes, Customs, which establish the opposite of those that were the most widespread behaviors) and the archaeological one. The archaeological methodologies relate to jumps, discharges and waste, deepening that primary access key to the interpretation of archaeological stratification, represented by the formative processes, particularly in the interpretative process of the jumps and therefore in the path, from jumps to history, which constitutes the title of the Sicilian convention of Sciacca-Burgio-Ribera, of which "Archeologia Postmedievale”Accepted the Acts. About twenty reports that bring "materials for" the history of the theme of waste and its disposal, in which the problem of the displacement of waste and its relationship with the context of consumption also emerges. The spaces of the butts, in the first place: wells, silos, cesspools, latrines, cavities. De-functionalised structures and only after their abandonment used as waste discharges, or structures built specifically with this function. These "materials for" the history of the problem, in addition to constituting a first survey on a regional basis (Sicily), highlight the complexity of the archaeological approach and the historical interpretation of material data. The disposal of ordinary and "extraordinary" waste (in relation to changes in function, ownership of buildings), waste from production, consumption, mixed waste and the social and cultural representativeness of materials.
