Recycling is defined as a process in which waste materials can again become usable. In the common belief of many peoples, recycling is only considered a contemporary manifestation linked to the economic and ecological politics of industrialized societies. Both archaeological and historical records, however, prove that recycling has its roots back in time, being a common behavior of our ancestors as well as of many past societies. At the Late Lower Paleolithic site of Qesem Cave, Israel, research has identified a particular lithic trajectory oriented towards the production of small flakes by means of recycling, in the exploiting of old discarded flakes to be re-used as cores. The high density of this specific production throughout the stratigraphic sequence of the cave demonstrates that lithic recycling was a conscious and planned technological choice aimed at providing small and sharp items, most probably in order to meet specific functional behaviors. This particular lithic behavior persisted for some 200 kyr of human use of the cave and is not related to any shortage of flint, as the vicinity of the cave is exceptionally rich in flint sources. The exceptional conservation of use-wear signs and residues has allowed the author to reconstruct the functional role of this specific production, highlighting its specialized nature mostly related to the processing of animal carcasses through accurate and careful actions. The aptitude towards specialization in a tool’s function and technology shows how advanced the cognitive capacities were of the Qesem hominins. Applying functional analysis based on the determination of wear on artifacts by means of optical light microscopes, scanning electron microscopy and chemical analysis (FTIR and EDX) provides a useful and effective approach for understanding the adaptive strategies of the Qesem Cave hominins who, while facing various situations, were able to find thoughtful solutions for different needs.
