The plastic scrap (waste) is converted in a plasma reactor 3 under reducing conditions in a plasma containing a substoichiometric amount of oxygen at a temperature above 1200 DEG C into a plasma pyrolysis gas comprising low-molecular-weight carbon fragments which is subsequently cooled to temperatures below 1500 DEG C. The cooled plasma pyrolysis gas is then fed, in compressed form as a fuel of high calorific value and high temperature, to a gas turbine 10 for the production of electricity. Waste heat from this turbine is utilised to generate steam, which is fed into a steam turbine 12 which likewise generates electricity. The process is suitable for plastic scrap of any desired composition and results in complete conversion into a gas of high calorific value, so that a high exergetic efficiency is achieved. <IMAGE> |
