NOVELTY - Recycling emissions of a device of metallurgy-, glass-, ceramic- or cement industry comprising at least one emitter (1) for producing the emissions of carbon dioxide containing exhaust gas, at least one electrolysis device (2) for splitting water into hydrogen and oxygen, and at least one chemical reactor (3) downstream the emitter and the electrolysis device for converting at least a portion of the exhaust gas and hydrogen into at least a synthetic base- or fuel material, comprises supplying at least a second emission of the emitter to the electrolysis device and/or the reactor.    USE - The method is useful for recycling emissions of a device of metallurgy-, glass-, ceramic- or cement industry.    ADVANTAGE - The method allows efficient utilization of the emissions of the device of metallurgy-, glass-, ceramic- or cement industry, and thus reduces the release of the emissions to the environment.    DETAILED DESCRIPTION - Recycling emissions of a device of metallurgy, glass-, ceramic- or cement industry comprising at least one emitter (1), which produces the emissions of carbon dioxide containing exhaust gas, at least one electrolysis device (2) for splitting water into hydrogen and oxygen, and at least one chemical reactor (3) downstream the emitter and the electrolysis device for converting at least a portion of the exhaust gas and hydrogen into at least a synthetic base- or fuel material, comprises supplying at least a second emission of the emitter for recycling to the electrolysis device and/or the chemical reactor in addition to the first emission comprising at least the portion of the exhaust gas. An INDEPENDENT CLAIM is also included for a device for performing the above method comprising the device of metallurgy-, glass-, ceramic- or cement industry comprising the emitter, the electrolysis device, the chemical reactor, at least a first device for supplying a first emission comprising at least a portion of the exhaust gas into the electrolysis device and/or the chemical reactor and at least a second device for supplying the second emission of the emitter to the electrolysis device and/or the chemical reactor.
