A hybrid grass support structure (100, 200, 300, 400, 500, 600, 710) comprising a growth medium layer (102), a stone wool layer (104) positioned below the growth medium layer, and a plurality of synthetic grass fibers (106). The growth medium layer comprises a growth medium. The synthetic grass fibers are incorporated at least into the growth medium layer.

A synthetic turf having a mat with a face arranged adjacent to a surface to coat, and a face opposite the face. The turf includes a plurality of blades made of a synthetic material that are connected to the mat. Above the face of the mat, an infill material is provided that is arranged among the blades. The infill material includes a predetermined percentage by volume of a vegetable material consisting of rachis of cereal ear. The infill material also includes a predetermined percentage by volume of a ligninic and/or resinous material of vegetable origin.

A carpet in synthetic grass of an entirely synthetic or hybrid type including a support extending mainly along a plane and defining an upper face and a lower face opposite the upper face, a plurality of synthetic grass threads constraint to the support to define fixing portions protruding from the lower face, glue spread on the fixing portions, a geotextile membrane in non-woven fabric arranged in correspondence with the lower face to cover the support on that side and in contact with the glue on the fixing portions, in which the geotextile membrane is included in the carpet in percentages between 0.5% and 3.5% with respect to the total weight of the carpet.

A turf sports field with a plurality of turf modules (100) having an upper turf surface and peripheral turf edges (5). The turf modules are deployed by means of a remotely operated or autonomously operated lifting and transport vehicle (103), which is provided with a lifting arrangement. When installed, the turf modules (100) are positioned adjacent previously installed turf modules, with a tolerance gap (105) between adjacently positioned turf edges (5) of different turf modules.

An artificial turf system (100) provides an existing artificial turf (102) including a plurality of existing artificial turf fibres (104) and an existing artificial turf backing (106) configured to carry the plurality of existing artificial turf fibres, a new artificial turf comprising a plurality of artificial turf fibres and an artificial turf backing layer, where the artificial turf backing layer comprises a carrier structure (302) configured to carry the plurality of artificial turf fibres, and a geogrid (114) positioned between the existing artificial turf and the backing layer of the new artificial turf.

An artificial turf mat includes a woven backing and a number of artificial grass blades connected thereto. The woven backing includes a leno weave of warp and weft threads where at least some of the warp threads and/or some of the weft threads are formed by melting threads. The artificial grass blades are woven into the woven backing. Each melting thread can include a temperature-resistant thread core and a meltable coating surrounding the thread core. A method for manufacturing an artificial turf mat includes weaving a backing and connecting a number of artificial grass blades thereto. The backing is woven by interweaving a number of warp and weft threads by means of leno weaving, at least some of the interwoven threads are formed by melting threads, and artificial grass blades are woven into the woven backing.

The invention relates to a completely or partially compostable turf (202, 300) the turf being a completely or partially compostable artificial turf or a hybrid turf (202) comprising a completely or partially compostable hybrid turf support, the turf comprising a decomposition inhibitor, the decomposition inhibitor in the turf being adapted to lose its functionality or leave the turf until a defined period of time has elapsed.

The invention provides for method for forming an artificial turf infill material. The method comprises selecting from a zeolite ore a microporous zeolite mineral using a selection criterion on specific surface area of the mineral, thereby providing the artificial turf infill material.
