The recycling and reuse of materials and objects were extensive in the past, but have rarely been embedded into models of the economy; even more rarely has any attempt been made to address the scale of these practices. Recent developments, including the use of large datasets, computational modelling, and high-resolution analytical chemistry are increasingly offering the means to reconstruct recycling and reuse, and even to approach the thorny issue of quantification. This volume is the first to bring together these new approaches, and the first to present a consideration of recycling and reuse in the Roman economy, taking into account a range of materials and using a variety of methodological approaches. It presents integrated, cross-referential evidence for the recycling and reuse of textiles, papyrus, statuary and building materials, amphorae, metals, and glass, and examines significant questions about organization, value, and the social meaning of recycling.
