  • a superior heat reduction or radiating capability keeps an artificial turf cooler (and thus keeps the overall sports field or stadium cooler to the players and audience), reduces heat damage to the tufted fibers, minimizes burning sensation to human skin when athletes fall, makes the artificial turf less susceptible to fire, allows the organic particles and other particles to degrade slower, and curtail other heat-related issues.
  • Fig. 6 depicts the specific gravity of three different types of organic materials (olive, cork, and coconut particles) and the result of the friction tests conducted on those materials.
  • Olive particles have a specific gravity greater than 1 to prevent floating and below 1.5 to meet certain sports requirements.
  • the tests are performed by a friction equipment that simulates the fall and sliding of an athlete on the surface of these materials by measuring the temperature of these materials, or the temperature elevation or burn felt by an athlete. The temperature also indicates or can be used to determine the amount of friction felt by the athlete (e.g., with the shoes, skin, or clothes). In the tests, conditions imitating athlete weights from 25 kg to 150 kg and falling or sliding speed up to 5 meter per second had been used on the materials in Fig. 6 (or artificial turf systems with such materials).
  • the result shows the average temperatures of the conducted friction tests.
  • the results shows that the olive pits have a lower temperature compared to that of cork.
  • coconut particles also exhibit a low temperature, they require water or need to be wetted in order to achieve that temperature (e.g., either 50% of the total coconut particles by weight had been soaked in water before they are tested or an amount of water equal to 50% of the total coconut particle weight had been added to the coconut particles.) This complicates the installation and preparation processes of an infill system and may make the artificial turf system incompatible with certain sports or disqualify the artificial turf system from meeting certain standards (EN 15330-1, EN 12235, etc.).
  • Fig. 7 depicts the result of a floatation test conducted on the olive, cork, and coconut particles.
  • Each glassware is filled with about the same amount of olive, cork, and coconut particles (e.g., the total weight of the particles is about the same) and then about the same amount of water is poured into each glassware. After letting the combination sits for approximately 30 minutes, the test shows that the olive particles stay in the bottom of the glassware (do not float in the water) whereas the cork and coconut particles float on or toward the surface of the water. This shows that the olive particles are more stable than the cork and coconut particles when they are filled with water or their infill systems are filled water.
  • olive particles are more likely to stay in place on rainy days and are more difficult to be dislodged from the artificial turf. Therefore, olive pit particles infill system is a better option in maintaining the structure and look of the infill system and keeping an even surface when water is involved (e.g., olive particles are less likely to be moved from place to place).
  • Fig. 8 depicts the result of a discoloration test conducted on the olive, cork, and coconut particles.
  • the discoloration test is conducted by placing olive, cork, and coconut particles in their respective containers with water and immersing or mixing the particles with water for several hours (e.g. about 2 hours).
  • a new, white piece of clothes e.g., made of cotton, polyester, nylon, or a combination thereof
  • the test shows that the olive particles leave behind the lightest color or almost no color on its respective clothes compared to those of the cork and coconut particles.
  • the coconut particles leave behind the darkest color. Therefore, the olive pit particles are more preferable and would make shirts, shorts, or other wears on the athletes less dirty, such as when they fall or slide.
  • embodiments based on the phrases consisting of and consisting essentially of are also contemplated.
  • Infill systems, artificial turf systems, and their counterpart methods consist of or consist essentially of the elements (e.g., weights, layers, materials, compositions, steps, or a combination thereof) mentioned in this application are contemplated.
