Bio-Based Infill Materials

Artificial Turf Infill: Innovative Bio-Solutions

Artificial turf, be it for sports pitches or decorative gardening, has traditionally been filled with synthetic infill for artificial grass. These solid particles have the purpose of stabilizing the turf by supporting the individual grass blades to keep them upright. In addition, they protect the grass base from degradation through sunlight. Rubber granules such as EPDM have long been considered the best infill for artificial grass due to their elasticity and light weight. However, environmental concerns about microplastic being released into nature have led to a demand for natural turf infill solutions.

Olive Stone Turf Infill Material and Sand for Artificial Grass

Most high-performance sporting turfs include several layers of turf infill. There is generally a hard base, a bottom layer of sand infill and a second layer of lighter, elastic granules. The sand is a heavy material to keep the grass blades upright, while the top layer of infill for artificial grass is generally of lighter weight and flexible texture. At, we have specialized in producing tailor-made infill for artificial grass on the basis of recycled olive stones. Customizable in grain size range and degree of hydrophobicity, our turf infill was created to replace rubber infill for artificial grass and to become the best infill for artificial grass - both in terms of mechanical and aesthetic properties.

Frequently Asked Questions (FAQ): Infill for Artificial Grass

1. How often should you add infill to artificial turf?

There are a number of factors that determine the lifespan of any artificial turf infill: location, i.e. weather and temperature conditions (wind, precipitation, ice, extreme heat, etc.), intended use and load. Artificial turf projects come in many different forms and there is a difference between high-performance sports turfs and leisurely used landscaping turfs. Please ask us for guidance on your specific project and we will give you a clearer idea of refill requirements. 

2. What are the minimum order quantities of your artificial turf infill?

We supply exclusively to business customers, i.e. turf designers or manufacturers. Hence, our landscaping fillers are sold by the metric ton and packaged in big bags. We can supply individual 25kg bags for testing purposes but you will obtain a much better value-for-money when purchasing larger volumes.

3. Is infill necessary for artificial grass?

Especially in artificial grass with high utilization - above all sports turf systems - the infill has an important function, which is to keep the grass blades upright and stable. Even the best artifical grass infill is only as good as the turf system as a whole, so it needs to be tailored to each specific type and function. Infill for artificial grass nowadays comes in very good biodegradable forms, so we can only recommend you to try our olive stone infill and convince yourself of the effects. 

4. What infill should I use for artificial grass?

From our point of view, two major aspects have to be considered when choosing the best infill for artificial grass: performance and sustainability. We believe that our renewable infill for artificial grass, which is made entirely from upcycled, refined olive stones, ticks all the boxes and sets a new state-of-the art. We provide customized granular infill solutions that work well in combination with sand, cork or even conventionally used rubber. Nearly any requirements can be met by means of customized grain sizes and even treated (hydrophobic) particles - for maximum efficiency, longevity and ecology. 

5. How much infill should I use for artificial grass?

As explained in question 4, there are very different infill solutions for different turf systems. In general terms, most artifical grass systems are filled with layers of several centimeters of turf infill. The more efficient the infill for artificial grass, the lower the necessary quantities. The most demanding artificial turf infill systems are probably those for sporting surfaces. Here, we recommend to use at least 8-12 kg per square meter of our olive stone infill. This figure can vary, depending on whether you wish to combine your artificial turf infill with sand and/or rubber granules. 

5. What is used as infill for artificial turf?

Traditionally: mostly rubber granules such as shredded tyres or EPDM. In recent times: any bio-based infill such as sand. The best infill for artificial grass from our perspective: anything not only bio-based but also compostable such as granules made from recycled agricultural by-products. At, we have developed performance infill solutions from hard, stable lignocellulosic materials such as olive stones. They offer the best mechanical properties and our manufacturing process contributes to waste reduction. 

6. Can you make bespoke artificial turf infill granules?

Yes, besides certain standardized grades, we offer tailored solutions - both in terms of grain size and particle treatment / hydrophobicity coating. To make sure that every customer receives the best infill for artificial grass, we are open to processing our natural raw materials into any possible particle size ranges.

10. Can I use play sand for artificial grass infill?

Play sand can be used as an infill for artificial grass, particularly because it adds weight to keep the turf straight and enhances the safety of the artificial lawn due to its fire-resistant properties. However, it's important to be aware of potential disadvantages. Sand infill can be messy, might trap pet odors, and could clog drainage systems in areas with frequent rainfall.
