● Recycling Challenges: Recycling synthetic turf is both technically and economically difficult. It is typically a composite of multiple materials: plastic grass fibers, rubber infill, and polyurethane or latex backing. Separating these materials thoroughly is costly, leading to very low recycling rates.
● Landfill Fate: After reaching the end of its lifespan (typically 8-15 years), the vast majority of synthetic turf is rolled up and sent to landfills. It occupies significant space there and is slow to degrade, potentially persisting for centuries. Incineration can release toxic gases.
3. Carbon Footprint from Production and Disposal
● Energy-Intensive Manufacturing: The raw material for synthetic turf is petroleum. Its manufacturing process is energy and water-intensive, involving petrochemical processing, extrusion, tufting, and backing, resulting in significant greenhouse gas emissions.
● Transportation Emissions: The transportation of heavy rolls of synthetic turf from factories to distributors worldwide also contributes to its carbon footprint.
4. Impact on Urban Ecosystems
● Heat Island Effect: Under the summer sun, plastic-based synthetic turf surfaces can reach temperatures of 60-80°C, far exceeding natural grass and ambient air. This exacerbates the urban heat island effect, affects the local microclimate, and poses a burn risk.
● Loss of Biodiversity: A patch of synthetic turf replaces potential natural vegetation, eliminating a micro-habitat. It cannot provide food or shelter for insects, birds, or soil microbes, creating a localized “desert” for biodiversity.
● Soil Sealing and Hydrological Impact: Although designed with drainage, large-scale installation of synthetic turf still seals the soil surface, impairing natural water infiltration and groundwater recharge.
