The environmental advantage of non-infill artificial turf is not simply that it contains “no rubber.”
The more important difference is the overall system architecture.
A conventional infilled synthetic pitch may require significant quantities of sand and/or polymeric infill. During installation and operation, these materials can require additional management, and infill migration can become an environmental and maintenance concern.
A non-infill system eliminates this additional infill component.
That can potentially provide several benefits:
No routine rubber infill replenishment
There is no requirement to periodically top up rubber granules simply to maintain the intended playing characteristics.
Reduced infill migration risk
Because there is no loose rubber or sand infill, there is less risk of these materials being carried away through footwear, drainage systems or maintenance activities.
Simplified maintenance
The maintenance system can be simpler because there is no need to redistribute or replenish infill.
Potentially easier end-of-life management
When the turf is designed using compatible or recyclable materials, the absence of loose infill can simplify removal and recycling.
However, non-infill does not automatically mean environmentally superior. A low-quality non-infill product made with unsuitable materials or difficult-to-recycle multilayer construction may still have environmental disadvantages.
