Bio-Based Infill Materials

Natural Sport Turf Infill

At we have developed sustainable solutions to optimize technical and environmental performance of state-of-the art sports turf. Most sporting surfaces built with artificial grass require efficient infill solutions to enhance resistance and lifespan. More specifically, granular matter is filled between the grass blades to keep them upright and to stabilize the turf.

Granular rubber, often made from shredded tyres, has been used for this purpose. In view of the problematic impact of microplastic on the environment, turf designers have increasingly sought natural alternatives. To cater to this demand, we have designed fully biodegradable infill solutions exclusively from side-stream resources.

Olea Fill – Olive Stone Infill for Artificial Grass Pitches

The largest surfaces created with artificial turf are generally football/soccer pitches. These areas have to live up to the highest quality standards and ensure an optimal sporting experience. To substitute the conventional rubber infill, offers Olea Fill – tailored natural infill grains with optimal performance criteria. Designed to be filled upon a base layer of sand, our infill is available in the two standard grain sizes 0.6-2.0mm and 1.3-3.0mm.

Olea Fill is made from refined crushed olive stones, a by-product of the olive oil production. This raw material combines excellent particle stability, hardness, moisture resistance and thermal resistance. It has frequently been used in FIFA-approved artificial turf systems on soccer pitches around the world.

Olea Fill is available in two variants: natural and hydrophobic / water-repellent. Our hydrophobic solutions are still biological and offer distinct advantages such as

  • Reduced dusting: even after intense utilization, the infill does not decay and remains stably in place
  • Outstanding moisture resistance, i.e. no flooding or expanding
  • Enhanced surface stability and abrasion resistance
  • Zero water absorption
  • Resistance against microbial contamination and decomposition

These advantages translate into a lifespan 2-3 as high as for the natural infill granules. The refilling cost can be significantly reduced and efficiency levels can be kept constant, even in areas of harsh weather conditions.

Bio-Based Infill Granules for Hard Sporting Surfaces

Olea Fill offers a vast range of possibilities to create innovative turf-free sports facilities such as tennis courts, racing tracks, gymnasias, horse riding rounds and swimming pool facilities. Most sporting surfaces require robust, slip resistant coatings with varying degrees of elasticity.

At we create granular additives for different surface coatings. All our granules are fully plant-based and primarily intended to integrate with numerous polymer systems. Their function as fillers, reinforcing fibres and texturizers comes with the following benefits:

  • Enhanced impact strength: our powdery infills have a hardness of +/- 3.5 on a Mohs scale. Their high-resistance particles are powerful reinforcing agents.
  • Lighter weight: its reduced density makes Olea Fill an ideal choice for any lightweight coatings. It can replace or complement conventional fillers, e.g. quartz or silica, and significantly reduce the overall material weight.
  • Anti-slip properties: when integrated in coatings, granular infills create a textured surface with high abrasion resistance. Very often, this effect is crucial for athlete safety and performance.
  • Optimal carbon footprint: obtained from renewable resources, our infill solutions comply with the highest sustainability standards. They are produced in a resource-efficient, purely mechanical upcycling process of agricultural by-products. All raw-materials are sourced locally and no waste or emissions are created during manufacturing.
