Abstract: Super absorbent polymers (SAP) generally exhibit adhesive and cohesive properties in the presence of moisture. To prevent unwanted absorption of moisture from the atmosphere, and in order to increase shelf life and handling life of SAPs; dried spent coffee ground powders may be mixed with the SAPs to prevent unwanted hydration of the SAP mixture. The natural oils in the grounds are responsible for providing a hydrophobic coating on the SAP particles.

Abstract: A system and method of rescuing playability of synthetic turf are disclosed. The system and method include kicking out infield material, mixing existing infield material with fresh infield material, injecting the mixed infield material, and kicking the bent and depressed turf fibers back to an upright position. The system and method also include performing the injecting pivoting the injectors in multiple directions. The system and method further include mixing water absorbent polymer particles with the mixed infield material and injecting into the turf. The system and method further include applying liquid materials to the fibers and material of the synthetic turf. The system and method further include injecting disinfectants into the turf.
