  • Patent number: 10052638
    Abstract: A method of recycling a filler included in artificial turf by sorting the filler into two or more materials, including: a first sorting operation of sorting the two or more materials based on a grain size; and a second sorting operation of sorting the materials, which are sorted by the first sorting operation and have grain sizes belonging to a predetermined range, based on specific gravity.
    Type: Grant

  • Publication number: 20140312526
    Abstract: The present invention relates to a method for recycling artificial grass containing fibrous material, and comprises: a supplying step for supplying the artificial grass comprising a base material, and a yarn; a separation step for separating the filler from the artificial grass yarn and the base material; and a crushing step for crushing the yarn and the base material of the artificial grass from which the filler is separated; and a reconstruction step for forming the artificial grass yarn and the base material that are crushed into recycled material. As a result, provided is the method for recycling the artificial grass containing the fibrous material, which can completely separate the filler and foreign material from the base material and the yarn that comprise the artificial grass and recycle the artificial grass yarn, base material, and the filler, thereby preventing environmental pollution.

  • Patent number: 7934599
    Abstract: Disclosed herein is a method for separation of construction waste. In the method, the construction waste, crushed to a predetermined size, is added to liquid in a precipitation tank and separated into components in the tank according to specific gravity, in which the liquid has a reference specific gravity lower than that of a component to be recovered but higher than that of the remaining components, such that only the component to be recovered is separated by precipitation to the bottom of the precipitation tank. According to the method, high-quality recyclable aggregate contained in the construction waste can be easily separated from other impurities through a simple process. Particularly, the reference specific gravity of the separation liquid is suitably adjusted so that the recyclable aggregate can be easily separated even from impurities (tiles, red brick, asphalt concrete, cement paste mass, etc.) heavier than water, unlike the prior separation process using an aerated water tank.
