Made from recycled material, artificial turf is environmentally friendly. The massive production volume and durability of rubber tyres means that they are really hard to dispose of and a truly environmentally friendly waste management solution is yet to be developed. Artificial turf can recycle massive amounts of used tire. On average, a soccer field or pitch will use about 100 tonnes of granulated tire rubber. The sports industry used nearly one million tonnes of granulated tire rubber for sports surfacing in the year 2009 alone. Artificial turf today is an environmentally friendly and cost efficient product that can easily be used as a replacement for natural grass on sports fields and in residential areas. The market for artificial grass in Europe and the United States is over one billion dollars and continues to grow. Depending on where it is located, an Artificial Grass can result in savings of about one million gallons of water annually. in recognition of the potential this product has to redefine water efficiency many water conservation institutions and cities in countries such as the united states have developed incentive schemes to convince home owners and real estate developers to switch to artificial grass. There are claims that the use of artificial turf systems saved roughly 5 billion gallons of water in the United States in the year 2011
The use of old tire as a source of rubber results in a significant reduction in the production cost of inlaid artificial turf systems. Though this may be the case, its use is not without a downside. Rubber contains a variety of antiozonants, vulcanizers, antioxidants and oil based plasticizers. Though it is commonly assumed that rubber is resilient to breakdown by environmental forces, heavy metals and organic chemical compounds held together by the rubber’s molecular structure can be slowly released through leaching and volatilization in a natural environment. Shredded tire has seen wide spread use in the discipline of civil engineering and numerous studies have focused on its interaction with the environment. The characteristic smell of rubber tires is indicative of the presence of sulphur and organic compounds which contain sulphur. Despite this odour, tires are not known to release significant quantities of semi volatile or volatile organic compounds, and so they are safe for use in artificial turf. Be that as it may, hundreds of volatile and semi volatile organic compounds have been identified in the exhaust gases released from pyrolysis and vulcanisation. Tests carried out at tyre shredding facilities have shown the presence of significant levels of pollutant chemicals such as styrene, methyl, and isobutyl. This finding points to the fact that though granulated rubber may be safe, the process used to create it have a significant environment al impact. This indirect impact warrants further research into safer methods for producing granulated rubber.
