  • the same tumbling process may also be used for any additional bio-based material.
  • the additional bio-based material may be tumbled together with the olive pit fragments to enhance the effectiveness of the tumbling process in rounding the sharp edges of the olive pit fragments.
  • the artificial turf infill comprises the rounded olive pit fragments prepared by the tumbling treatment process.
  • Rounded as this term is used here, means that the fragments do not have sharp edges which can cause skin injury to the users of the artificial turf.

  • heat treatment means that the olive pit fragments are heated to a sufficiently high temperature, that the heat treatment not only reduces the equilibrium moisture of the olive pit material and eliminates any residual olive odor, but also modifies their chemical structure.
  • Chemical modification of the olive pit structure may be measured by X-ray photoelectron analysis (XPS) of the oxygen to carbon ratio of the material.
  • thermally treated olive pit material means that the olive pit material has been sufficiently heated to show at least a 3%, preferably at least 5%, and more preferably 5% to 10 % reduction in the oxygen to carbon ratio compared to thermally untreated olive pit material as measured by XPS analysis.
  • the thermal treatment heats the olive pit material to a temperature higher than 150°C, in particular 160 °C to 250 °C, and more in particular 180 °C to 250 °C.
  • Thermal treatment at these higher temperatures has the benefit of increasing the resistance of the olive pit fragments against moisture-induced biodegradation, which is particularly beneficial in humid regions or when the artificial turf infill comprises a zeolite which is irrigated frequently before and during a game to cool the sports field and the players.
  • heat treatment at the elevated temperature above 130 °C and in particular at a temperature of 150 °C to 250 °C not only removes any residual moisture or odors but, more importantly, also changes the chemical structure/composition of the hemicellulose, cellulose and lignin components of the olive pit fragments which results in substantially reduced hygroscopicity or effectively almost zero hygroscopicity for the thermally treated olive pit material at such temperatures. As a result, the olive pit material becomes resistant to natural biodegradation and is also much less likely to suffer from microbial infestations.
  • thermally treated artificial turf infill of the present invention particularly suitable to be used with microporous zeolite particles that can be used to store water during watering of the turf and release it gradually thereafter, thus, cooling the turf and the athletes (or users) of the turf without reducing the useful lifespan of the infill (and of the turf) due to the increased moisture conditions.
  • the artificial turf infill and artificial turf using the artificial turf infill of the present invention can be watered more frequently and also last longer than existing turfs.
  • Heating for the thermal treatment may be performed with any suitable means.

  • the heat treatment may be performed separately and independently of any tumbling treatment, for example in an oven.
  • the temperature and duration of the thermal treatment may be adjusted as may be needed for adjusting the effects of the heat treatment on the properties of the olive pit material.
  • the duration of the tumbling treatment of the olive pit fragments may range for a period of 1 minute to 8 minutes, and in particular for a period of 2 minutes to 6 minutes.

  • these time periods are provided only as examples, and longer periods may be used without departing from the scope of the present invention.
  • the tumbling and/or thermal treatment may last from a few minutes to a few hours.
  • the method comprises sieving the thermo-tumbler product to remove at least some of the thermo-tumbler product olive pit particles having a size of less than 63 ⁇ m.
  • the removed olive pit particles may be used for forming a stabilization layer for the infill.
  • the product from the thermo-tumbler is used without separation or sieving to form an infill layer for an artificial turf.

  • fragments of at least one other bio-based material may also be fed in a thermo-tumbler and mixed together with the olive pit fragments.

Keeping this level of olive pit particles has been found to be beneficial because the olive pit particles allow for a higher packing density of the infill.
