Synthetic Grass - General 

Q: What is synthetic turf?

The latest generation of synthetic turf is a grass-like ground cover that replicates lush natural grass in appearance and function. When used on athletic fields, it provides a consistent year-round, all-weather playing surface built to withstand extended use without downtime for recovery. As a landscape cover, synthetic turf provides a low maintenance, weed-free surface that doesn't need to be watered or fertilized, and is available in styles that look like the grass types that are prevalent locally.

Q: How is synthetic turf made?

Most synthetic turf systems installed today include a drainage layer, a multi-layered backing system, and resilient "grass" blades that are infilled with a granular filler to resemble natural turf. "Infilled" means that the man-made grass blades are interspersed with a top soil created with sand and/or granulated recycled tire rubber or other infill materials that provide the necessary stability, uniformity, and resiliency. Each blade customarily stands above the infill material. The typical blade length and system characteristics are determined by the specific activity requirements. In some applications, the synthetic turf system includes a pad or elastic layer underneath the turf, often in combination with lower pile height and less infill.

Q: How is the new generation of synthetic turf different from that of the past?

Increasing demand for high quality playing surfaces and intense competition for field accessibility has given rise to a new generation of synthetic turf systems that replicate the look and feel of lush, natural grass. While the first artificial turf systems used in the 1960’s and 1970’s were hard, significant advancements have been made during the past few decades. By the 1990’s, the first synthetic turf systems with sand and rubber infill were introduced, which dramatically improved player performance and safety. Today’s synthetic turf, used by many NFL franchises, as well as member associations and teams of the Union of European Football Associations (UEFA), Fédération Internationale de Football Association (FIFA), the International Rugby Board and other international sports federations, combines the playing characteristics, look and feel of natural turf, with the advantages of increased frequency of usage, extra revenue generation, safety, longer playing sessions, fewer canceled games, and lowest cost per playing day.

Q: Why has synthetic turf become so popular over the past few years?

Synthetic turf is a smart solution for playing fields and landscape that have become unsafe and unsightly from overuse or severe climatic conditions. A grass field simply cannot remain lush and resilient if it is used more than three to four days a week, or in the rain, or during the months when grass doesn’t grow. This fact, coupled with an escalating need for durable fields that accommodate multiple sports teams and activities, the high cost of maintaining a grass sports field, and the need to conserve water, have prompted a rising number of schools and parks to turn to synthetic turf to meet their program needs. Today’s synthetic turf is designed to simulate the experience of practicing and playing on the best grass fields.

Demand has grown to the point where more than 8,000 multi-use synthetic turf sports fields are now enjoyed in North American schools, colleges, parks and professional sports stadiums. About half of all NFL teams currently play their games on synthetic turf and, since 2003, over 70 FIFA U-17 and U-20 World Cup matches have been played on synthetic turf soccer fields.

Q: How popular is synthetic grass for landscape and recreation use?

Synthetic grass for landscape, golf and other recreation applications is the fastest growing segment of the synthetic turf market. Over 35 million square feet of synthetic grass for landscape and recreation use was installed in 2012.

Q: How is synthetic turf being used in the landscape and recreation market?

Thousands of homes, businesses, golf courses, municipalities, parks and tourist attractions like Disneyland and Steve Wynn’s Las Vegas resorts have turned to synthetic grass to provide a lush, attractive landscape solution that requires minimal resources and maintenance while saving millions of gallons of water each year. It is also a smart way to beautify public spaces such as highway medians and airport landing strips that would otherwise be difficult and expensive to maintain. Synthetic grass reduces city maintenance costs, freeing tax dollars for other purposes.

Synthetic turf also promotes greater utilization of land, as you can do more with the same space surface than with natural grass. Rooftops once deemed unusable for high rises and residential buildings can now feature inviting green area. Hotels that had to restrict the use of lawns for parties and events can now schedule as many functions as they can book.

Q: What are the different types of infill materials?

Coated Rubber Infill: Both ambient and cryogenic rubber can be coated with colorants, sealers, or anti-microbial substances if desired. Coated rubber provides additional aesthetic appeal, reduction of dust by products during the manufacturing process and complete encapsulation of the rubber particle.

EPDM Infill: EPDM (Ethylene Propylene Diene Monomer) is a polymer elastomer with high resistance to abrasion and wear and will not change its solid form under high temperatures. Typical EPDM colors are green and tan. EPDM has proven its durability as an infill product in all types of climates. Its excellent elasticity properties and resistance to atmospheric and chemical agents provide a stable, high performance infill product.

Organic Infill: There are several organic infills available in the North American market, all utilizing different organic components, such as natural cork and/or ground fibers from the outside shell of the coconut. These products can be utilized in professional sports applications as well as for landscaping. At the end of its life cycle it can be recycled directly into the environment.

Sand (Silica) Infill: Pure silica sand is one of the original infilling materials utilized in synthetic turf. This product is a natural infill that is non-toxic, chemically stable and fracture resistant. Silica sand infills are typically tan, off-tan or white in color and - depending upon plant location – may be round or sub-round in particle shape. As a natural product there is no possibility of heavy metals, and the dust/turbidity rating is less than 100. It can be used in conjunction with many other infills on the market to provide a safe and more realistic playing surface. The round shape plays an integral part in the synthetic turf system. It is important that silica sand have a high purity (greater than 90%) to resist crushing and absorption of bacteria and other field contaminants. Silica sand can either be coated with different materials as a standalone product or can be used to firm up in combination with traditional crumb rubber infill systems.

Coated Silica Sand Infill: This class of infill consists of coated, high-purity silica sand with either a soft or rigid coating specifically engineered for synthetic turf. These coatings are either elastomeric or acrylic in nature (non-toxic) and form a bond with the sand grain sealing it from bacteria to provide superior performance and durability over the life of a field. Coated sand is available in various sizes to meet the application’s needs. 

Depending on the amount and type of infill, coated sands can either be used with or without a pad and are available in various colors. All of the coatings are non-toxic and are bonded to the quartz grain for superior performance and durability over the life of your field. These materials are typically used as a homogenous infill which provides both ballast and shock absorbing qualities to a synthetic turf application.

TPE Infill: Thermo plastic elastomer (TPE) infill is non-toxic, heavy metal free, available in a variety of colors that resist fading, very long lasting, and 100% recyclable and reusable as infill when the field is replaced. TPE infill, when utilizing virgin-based resins, will offer consistent performance and excellent g-max over a wide temperature range.


Health & Environmental Impact

Q: How does synthetic turf impact the environment?

Synthetic turf has a measurable, positive impact on the environment. Depending on the region of the country, a typical grass sports field requires between 500,000 to a million gallons of water or more each year. During 2010, between four to eight billion gallons of water were conserved through its use. According to the U.S. Environmental Protection Agency(EPA), the average American family of four uses 400 gallons of water a day. Therefore, a savings of four to eight billion gallons of water equates to the annual water usage of over 27,000 to 55,000 average American families of four.

Tax credits and rebates are being offered to residential and corporate users by an increasing number of local governments in light of the tremendous impact on water conservation. The Southern Nevada Water Authority estimates that every square foot of natural grass replaced saves 55 gallons of water per year. If an average lawn is 1,800 square feet, then Las Vegas homeowners with synthetic turf could save 99,000 gallons of water each year or about $400 annually. In Atlanta, homeowners could save $715 a year, not including much higher sewer charges. 

The estimated amount of synthetic turf currently installed has eliminated the need for millions of pounds of harmful pesticides and fertilizers, which has significant health and environmental implications. For example, according to the North Carolina Department of Environment and Natural Resources, polluted storm water runoff is the number one cause of water pollution in their state, with common examples including over fertilizing lawns and excessive pesticide use.

In addition, synthetic turf helps reduce noxious emissions (the EPA reports that a push mower emits as much pollution in one hour as 11 cars and a riding mower emits as much as 34 cars) and reduces grass clippings, which the EPA states are the third largest component of municipal solid waste in landfills.

Q: Is synthetic turf safe?

More than 50 independent and credible studies from groups such as the U.S. Consumer Product Safety Commission, and statewide governmental agencies such as the New York State Department of Environmental ConservationNew York State Department of Health and the California Environmental Protection Agency, have validated the safety of synthetic turf (see Position Statements to learn more). 

Recent highlights include:

  • In October 2010, the California Office of Environmental Assessment completed its multi-year study of air quality above crumb rubber infilled synthetic turf, and bacteria in the turf, and reported that there were no public health concerns.
  • In July 2010, the Connecticut Department of Public Health announced that a new study of the risks to children and adults playing on synthetic turf fields containing crumb rubber infill shows "no elevated health risks.”
  • The California EPA released a report dated July 2009 which indicated there is a negligible human health risk from inhaling the air above synthetic turf.
  • Independent tests conducted by the New York State Department of Environmental Conservation and New York State Department of Health, released in May 2009, proved there were no significant health concerns at synthetic turf fields.
  • In July 2008, a U.S. Consumer Product Safety Commission staff report approved the use of synthetic turf by children and people of all ages.

Q: Should I be concerned about lead in my field?

Absolutely not. In April 2008, concerns about lead in synthetic turf arose when elevated levels were found in several New Jersey fields. At the time, the lead chromate that was used to promote colorfastness in synthetic turf was encapsulated to prevent it from being readily absorbed by the body or released into the environment. The issue was resolved, and the safety of synthetic turf was validated on July 30, 2008 when the U.S. Consumer Product Safety Commission staff released the results of its study of lead in synthetic turf, and concluded that "young children are not at risk from exposure to lead in these fields.” Here is their full statement. In over 40 years there has never been an instance of human illness or environmental damage caused by synthetic turf.

Today, synthetic turf is made without lead as a pigment ingredient. This change in the pigment formulations was a voluntary and responsible response by the synthetic turf industry to the CPSC's request of all industries that lead be removed from all products, if possible.

Q: What impact does heat have on my synthetic turf field?

During the summer months on hot sunny days, when synthetic turf is exposed to direct sunlight, some synthetic turf fields have reported surface temperatures significantly hotter than the surface temperature of a natural turf field. In such conditions, many coaches will schedule practices and games for the cooler times of day, and limit the number and duration of practices. They will also follow, as STC advocates, the heat-acclimation guidelines published by the National Athletic Trainers' Association.

Some field managers might opt to water their fields, while others advocate misting the athletes and keeping them properly hydrated. A misting station normally needs only five gallons of water per hour based on full use. On a typical day, when the heat is at its peak for four to six hours, that equals 20 to 30 gallons of water.
