Sasil undertook studies with the aim of obtaining recyclable plastic-free glass & making polymers almost glass-free. To achieve these objectives, new technologies have been developed. It was necessary to develop a system for separating PVB from glass & glass from PVB, & to develop a polymer cracking technology with the aid of ACTI (Am Comb Tec Inc). The first test results demonstrated that the minimum size of the energy recovery unit must be, for economic reasons, 5,000/tpa (polymers) which was not currently achievable. For this reason, the PVB was associated with other polymers that came from glass cullet plants. In this paper, current technologies are illustrated & results of long term trials in polymer separation from glass & the use of glassy sand for container production & polymer cracking for hydrocarbon C1-C6 production, are described.
