Infill material for synthetic turf surface and related production process

Production process of an infill material for a synthetic turf surface, wherein the infill material comprises a plurality of particles, the process comprising:

• providing fragments of a plant material;
• providing a polymeric material selected in the group:
• polylactic acid (PLA), polybutylene adipate terephthalate (PBAT), polyglycolic acid (PGA), polycaprolactone (PCL), poly(lactic-co-glycolic) acid (PLGA), poly-(2-hydroxyethyl-methacrylate), poly-ethylene-glycol (PEG), chitosan, hyaluronic acid, a poly-hydroxy-alkanoate (PHA), or combinations thereof;
• heating and mixing said fragments of said plant material and said polymeric material for obtaining a blend comprising said polymeric material in softened state with said fragments of said plant material dispersed in said polymeric material;
• and
• cooling said blend into solid state and grinding said cooled blend for obtaining said plurality of particles, wherein each of said particles comprises a polymeric matrix made of said polymeric material, and a reinforcing filler dispersed in said polymeric matrix, wherein said reinforcing filler is made of said plant material.
