In this article, the authors investigate the effectiveness of glass and metal recycling in Roman towns. The comparison of sealed primary deposits (reflecting what was in use in Roman towns) with dumping sites shows a marked drop in glass and metal finds in the dumps. Although different replacement ratios and fragmentation indices affect the composition of the assemblages recovered in dumps, recycling appears to have played a fundamental role, very effectively reintroducing into the productive chain most glass and metal items before their final discard. After presenting a case study from Pompeii, the authors examine contexts from other sites that suggest that recycling practices were not occasional. In sum, recycling should be considered as an effective and systematic activity that shaped the economy of Roman towns.
