Artificial turf is gaining popularity for sports fields, landscaping and pet facilities. It is a more reliable surface than natural grass, especially during rainy weather. It also meets traction, stability and rotation standards set by sports federations and leagues.
However, stringent environmental regulations restrict growth. For instance, Boston has banned the use of PFAS-containing synthetic granules.
Cost
While many sports teams and homeowners have exchanged high water costs, allergens, and hours spent grooming real grass for the ease and convenience of fake grass, it is not without its issues. One is that it can create a buildup of dust and unpleasant odors. Another is that the plastic material absorbs heat and can be uncomfortable to play on in the summer. Finally, it can’t be recycled because it is a petroleum-based product and ends up in landfills after its lifespan of 8-15 years.
The cost of artificial turf varies by the type of blade shape, the size and scope of the project, as well as any add-ons. The price per square foot also varies depending on the manufacturer. In general, the traditional straight-blade turf is cheaper to install than other specialized grass blade shapes that offer more performance characteristics.
Other costs associated with the installation of artificial turf include the amount of time needed to complete the project and any additional materials or labor required. For example, edging around the perimeter of the turf is typically done with metal or concrete edging. The cost of these items will vary based on the chosen design and can be as much as $345 per linear foot.
A growing concern with artificial turf is the potential for exposure to chemicals that are not removed in the manufacturing process. Specifically, the crumb rubber infill (which is made of the end-of-life tires) may expose players to hazardous chemicals such as polycyclic aromatic hydrocarbons, phthalates, and per- and polyfluoroalkyl substances (PFAS). These are found in both the rubber granules and the plastic coating of the lining, which breaks down into silica dust — a lung hazard — and small black particles that can easily migrate into homes and vehicles. The Children’s Environmental Health Center at Mount Sinai recommends natural grass fields and playing surfaces as the safest option for children. Homero Harari is an assistant professor of environmental medicine and climate science at the Icahn School of Medicine at Mount Sinai. He is an expert on the health impacts of hazardous materials and regularly speaks to community groups about this issue.
Maintenance
Artificial turf can seem like the perfect solution, replacing thirsty lawns with something that plays like grass but requires no water and little maintenance. However, there are some important considerations to take into account.
One big problem with older types of turf is that it can get incredibly hot during the summer, burning bare feet and even shoes if people walk on it without socks or sneakers. Fortunately, new turf technologies are designed to regulate temperature more effectively.
Another concern is that most synthetic turf fields use crumb rubber infill, which is made from old tires. Over time, this can leach out of the turf and pollute soil and water sources. This has led to increased scrutiny of the health and environmental impacts of these fields, especially when they are located near rivers and other water resources. Some states are now requiring that schools and other public facilities that use artificial turf install an ecosystem-balancing native grass garden to offset the impact of their sports fields.
A third problem with turf is that it can be hard on kids’ and pets’ bare feet. Unless it’s covered with soft grass or a cushioning layer, it can cause scrapes and abrasions when kids fall while playing on it. Some manufacturers have been working to improve this by adding extra padding or putting the turf on a softer base.
In addition, it’s important to keep in mind that turf is essentially a sheet of green plastic that looks pretty much the same throughout the year. You’ll lose the pleasure of a lush, colorful yard full of flowers and other plants that thrive in the local ecology. You’ll also miss out on the sound of hummingbirds buzzing in the trees and migrating birds passing overhead. Taking steps to return your yard to natural vegetation can help bring these creatures back, providing habitats and food for frogs, bees, birds, butterflies, and other local wildlife that have been impacted by climate change and habitat loss.
Environment
Artificial turf has become a popular option for sports fields and residential lawns. It is low maintenance, durable, and requires no watering, making it a great option for people living in drought-prone areas. However, it is not without its drawbacks. Some of the synthetic grasses contain harmful chemicals that can negatively impact the environment and human health. A growing body of evidence shows that these chemicals can cause cancer, neurodevelopmental disorders, and other health conditions. To minimize this risk, consumers should choose synthetic grass products that use recycled materials and meet rigorous environmental and health standards.
Since the first generation of artificial turf was introduced in 1967, manufacturers have made significant improvements to the material and manufacturing process. The latest technology has enabled the production of synthetic grass that is more realistic and comfortable to play on. This improvement has also led to a greater variety of options in terms of color, texture, and durability. Many manufacturers offer a wide range of synthetic grass options to suit any budget and aesthetic preferences.
Synthetic grass is typically composed of several synthetic layers that are laid over natural soil. These include a stone foundation layer, a plastic shock-absorption layer, a weed barrier and fabric layer to prevent weeds from growing, a rubber infill layer that keeps the fake grass blades upright, and a layer of plastic grass fibers. The synthetic fibers are usually made of nylon, polypropylene, or polyethylene and can be mixed with other polymers or polyurethane. The crumb rubber infill is usually made of recycled tires. Studies have shown that exposure to this component can lead to a variety of health issues including cancer, neurological problems, and endocrine disruption.
These layers can release chemicals into the air and groundwater. The most common chemicals are per- and polyfluoroalkyl substances (PFAS). These are widespread in the environment, have been found in drinking water, and can be ingested by humans and animals. PFAS can also be absorbed through the skin. In addition to causing health issues, these chemicals can damage the environment and wildlife.
Another concern with synthetic turf is that it can be difficult to recycle or reuse once it is worn out or damaged. It is often disposed of in landfills or informal stockpiles. It may also be burned or illegally dumped, which can release dangerous chemicals into the environment.
Safety
Artificial turf is becoming more popular for athletic fields and playgrounds. It’s easier to maintain and can be used in a wide range of weather conditions. It also reduces the risk of impact injuries by providing a padded surface. However, there are some concerns about the safety of these types of fields. For example, it can be hard on children’s feet and may cause abrasions. It can also get very hot and cause players to overheat and dehydrate easily.
Manufacturers have made significant strides in improving the safety of artificial turf products. One innovation has been the addition of shock-absorption technology, which helps reduce player injuries by reducing the force of impact. Another improvement is the addition of antimicrobial technology, which kills bacteria that can lead to skin infections. Manufacturers have also developed special infill materials that are more resilient than traditional sand.
Despite the improvements, some experts are concerned about the safety of synthetic turf fields. For example, the crumb rubber infill material may contain toxic chemicals that can be released into the air when it wears off. This is a concern for children, who are more likely to be exposed to these chemicals than adults. They may also bring these chemicals home on their shoes and clothes, where they can be ingested or inhaled.
In addition to the safety concerns, many people worry about the environmental impact of artificial turf. Artificial turf lasts for eight to ten years before it needs to be replaced. At the end of its life, it is typically disposed of in landfills or through incineration, contributing to solid waste pollution. The infill material can also migrate into watersheds, where it can contribute to microplastic pollution.
While there are some drawbacks to using synthetic grass, it is a good choice for people who cannot afford to maintain natural lawns and want to save money on maintenance costs. However, people should consider the full life cycle of the field before making a decision. This includes the cost of maintenance, disposal, and replacement. They should also take into account the loss of wildlife habitat and the contribution to climate change from the removal of green space.
