Also contained 7 to 1% polyvinyl chloride PVC Pure polyethylene was pyrolysed in the first phase. Defined quantitiesof PVDCwereadded lat- . er (7%) in order to investigate the influence of chlorine-bearing plastics on the pyrolysis pro- cess. Polyethylene was used either in pure granule form or originated from various sources. For example, PE drums were available which had to be comminuted before pyrolysis. Another source of PE wasa ricultural film. Large quantities of oil containers containing small residues of lubricant oil and pxarmaceutical bottles with solvent residues were also available, but were only used experimentally due to their liquid content. The plastic from domestic refuse originated from collection from Hamburg. It consisted mainly of plastic bottles. Polyester PET originated from production waste from ,,Trevira" factory and was very clean. It was pyrolysed on its own or mixed with PE. 2 The valuable materials obtained, .. gas, oil and carbon black, were to be investi ated as regards their market value or the possibility of their being used internally in the ?ant. The necessary disposal routes for the solid residues, .. sand, inert material and reacted aggre- gates, were to be examined and proof provided of compliance with existing regulations. study was compiled with the following goals: - Documenting the current status of plastics pyrolysis technology. - Establishing whether the boundary conditions necessary for the commercial use of plastics pyrolysis are fulfilled, such as potential, marketability of the valuable materials produced, disposal of residues and locations. - Determining whether the economy of plastics pyrolysis can be improved through combi- nation with other types of plant, and illustrating the resultant reciprocal influences. - Determining sensible plastics pyrolysis plant sizes and the costs arising from their construction and operation. - Clarifying the possibilities of obtaining permits for plastics
