The invention relates to recycling and reuse of graphite wastes, and in particular to a method for recycling and reusing margin and corner scraps of graphite plates and paper to produce low-sulfur ultra-thin graphite paper. The method for recycling and reusing the margin and corner scraps of the graphite plates and the paper comprises the following steps: I, performing primary crushing on a graphite margin and corner material by using a universal crushing machine, wherein the crushing granules are smaller than 3mm; II, further crushing granules less than 3mm into powder of which the particle size is less than 45[mu] m in a fine steam crushing manner; III, uniformly mixing the powder with an adhesive and expanded graphite in a ratio; IV, performing thermal treatment on the mixed powder of the step III at 900-1050 DEG C, thereby obtaining ultra-thin graphite paper and various graphite products.
