The invention relates to a method for producing a sheet from renewable raw materials. In the method, after mixing a composition to produce a sheet from renewable raw materials, this composition is applied to a conveyor belt. Protruding materials or unevennesses are eliminated with the aid of a device, preferably a simple doctor blade. Without supplying heat, the composition is then subjected to a first drying process on the conveyor belt, before the endless sheet created in this way is cut into sections. The sections are then passed on to final drying in a storage device. After complete drying, regions at the extremities of the sections that have been adversely affected by cutting up the endless sheet are removed from these sections and chopped up into chips. These chips are returned to the further production process in a final method step by feeding them into the composition for producing a sheet from renewable raw materials.

The invention relates to a novel form of wave energy conversion in which a suitable installation that is located in the immediate influx region of the waves, i.e. in the immediate vicinity of the water/shore, absorbs the force of the waves in continuous motion and converts said force into another force. Said force can then be used for all force conversion units. The aim of the invention is to develop a device which can optimise the use of the energy contained in the waves in the shore region or rivers. According to the invention, one or more wave impeller wheels are mounted horizontally in a frame in a height-adjustable steel construction that is situated in the water, the discontinuous rotation of said wheels being converted by gears into a continuous rotation. The distance between the wave impeller wheels is dimensioned according to the average frequency of the wave.
