Biodegradable grass infill - GreenFill

 Senbis GreenFill


Industry and application area

Fully in-soil biodegradable grass infill for artificial grass fields as an alternative to e.g. the current rubber granulates.

In artificial sport turf systems often rubber granulates are used as infill to make the pitches more durable, weather-proof and to add shock absorption and traction. The granulates are usually made from scrap end-of-life tyres (ELTs) that are cut into smaller forms. In the past years there have been discussions on whether or not these rubber granules cause health issues to both adults and children playing on these fields. Moreover, several thousands of tons of rubber granulates end up in the environment every year polluting the environment with microplastics and toxic components that are capsulated in the tyre rubber.

For these reasons the European Chemicals Agency (ECHA) is currently working on a proposal to restrict the use of rubber granules. If the proposal is agreed upon, no more rubber granules may be used on sport fields from 2020 onwards. More information on the restriction can be found in this article of the ECHA website.

Sustainability aspect

  • In-soil biodegradable
  • Good sports performance 
  • Low abrasion

Current status

GreenFill has been fully developed by Senbis. In October 2019 a 20x30 meter pilot field has been installed at SC Erica in the municipality of Emmen. The test field has been realized in cooperation with Sweco, Antea Sport and Edelgrass. It was supported with subsidies from the province of Drenthe. The official opening took place on December, 14th 2019.

GreenFill shows excellent sport performance on the field and fully degrades to water, CO2 and humus when ending up in nature.

The official market launch of GreenFill is planned during the Chemport Expo on the 7th of April 2020.
