A new recycling system for waste plastic is proposed, in which waste plastic and heavy oil are mixed to produce new fuel. In our previous work [1,2], we pointed out that the mixture fuel, at temperatures around 150 deg. C, is suitable as an alternative fuel for diesel generation systems. The mixture fuel, however, is difficult to handle due to hardening at room temperature.
In this study, the emulsification of waste plastic and heavy oil mixtures with water is examined. Using a surfactant, emulsions of either polyethylene (PE) or polypropylene (PP) with water have been successfully produced, with 33% water content. The emulsified fuels were tested in a diesel engine system, and indicate that the new emulsified fuel can be used as liquid fuel at room temperature, with performance close to that of heavy oil without changes to the test engine system other than injection timing.
