NOVELTY - Apparatus for pyrolysing/gasifying material containing organic content, comprises: an oven (10) mounted for rotation on support (16), where the oven has inlet (20) for receiving hot gas having low/zero oxygen content to heat the material so as to process it to produce syngas, and outlet (24) for syngas; electromagnet (28) disposed in/adjacent the oven so as to create a magnetic field; ferrous elements (30) freely disposed within the oven; and unit (32) for controlling electromagnet and rotation of oven such that when activated electromagnet retains ferrous elements as the oven rotates.    USE - As apparatus for pyrolysing or gasifying material containing an organic content (claimed) such as wood.    ADVANTAGE - The present apparatus breaks the material into smaller pieces, and increases its surface area available to react with oxygen in the hot gas passing through the oven and thus reduces the time taken to gasify the material. Decreasing the overall processing time increases the efficiency of the waste processing as the amount of time the hot gas needs to be provided is reduced. The gas released as syngas can be used for energy production and accordingly by reducing the amount of energy that needs to be used for producing the hot gas (by reducing the amount of time the hot gas is needed for) the overall percentage of the energy recovered that is available for export is increased. Moreover, the ferrous element has a number of grooves around its edge separating the surface into several raised shapes. These raised features improve the friction as the elements impact on the material and assist in preventing them from glancing off large pieces which is more likely if the elements have a smooth spherical outer surface.    DETAILED DESCRIPTION - An apparatus for pyrolysing or gasifying material containing an organic content, comprises: an oven (10) mounted for rotation on at least one support (16), where the oven has an inlet (20) for receiving hot gas having a low or zero oxygen content to heat the material in it so as to process it to produce syngas, and an outlet (24) for the syngas; an electromagnet (28) disposed in or adjacent the oven so as to create a magnetic field in it; several ferrous elements (30) freely disposed within the oven; and control unit (32) for controlling the electromagnet and the rotation of the oven such that when activated the electromagnet retains the ferrous elements as the oven rotates. The apparatus further comprises at least one gas analyzer (26) for analyzing the composition of the gas exiting the oven. An INDEPENDENT CLAIM is included for a method for pyrolysing and/or gasifying material containing an organic content, involving: providing an oven mounted for rotation on at least one support, where the oven has an inlet and an outlet; providing a flow of hot gas having a low or zero oxygen content to the oven via the inlet to heat the material in it to process it to produce syngas; providing an electromagnet disposed in or adjacent the oven so as to create a magnetic field in it; providing several ferrous elements freely disposed within the oven; and activating the electromagnet to retain the ferrous elements as the oven rotates.
