Method and plant for recycling the infill of synthetic turves

A method for recycling a roll of a synthetic turf strip having a mat to which a plurality of synthetic grass filaments are attached and between which is an infill, said infill being formed by a plurality of different granular materials including at least sand granules, polymeric material granules and synthetic grass filaments, said method comprising the following steps:

• unrolling the strip of synthetic turf,
• mechanically removing the infill from the strip of synthetic turf,
• collecting the removed infill and rolling up the strip of synthetic turf again,
• drying the infill by a flow of hot air,
• screening the infill through a plurality of successive screens each having different calibrated passage holes by subdividing the infill into a plurality of groups of granular material having different size ranges,
• separating each group of granular material into two subgroups based on the difference in density of the materials,
• conveying separate subgroups of granular materials to different collection containers.
