Abstract
An artificial turf infill comprising a thermally treated olive pit material. The thermally treated olive pit material exhibits exceptional antimicrobial resistance and biodegradation resistance in moist and humid conditions. In some embodiments, the thermally treated olive pit material comprises olive pit fragments that have been heated to a sufficiently high temperature to chemically modify the structure/composition of the hemicellulose, cellulose and lignin components and render them resistant to biodegradation in moist/humid environment.
Claims20
An artificial turf infill comprising a thermally treated olive pit material,
- wherein the thermally treated olive pit material has a bimodal size distribution with a major mode and a minor mode,
- wherein the major mode comprises olive pit fragments and has a peak between 0.5 mm to 4.0 mm, and
- wherein the minor mode comprises olive pit particles having a size less than 63 μm and has a peak at less than 63 μm.
A method for making an artificial turf infill, the method comprising:
- subjecting an olive pit material to a thermal treatment at a temperature of 150° C. to 250° C.;
- and
- using the thermally treated olive pit material as the artificial turf infill or as a component of the infill.
