Handling of the materials

Rubber powder & granulates are safe to manipulate with bare hands

Polyurethane binder

The use of gloves and safety glasses is recommended when manipulating the polyurethane binder
Be careful about the container where you want to do the mix, the binder risks to remain into without possibility of removing it.
The binder is volatile, you should process of the mix under a hood or outside. Avoid to breathe it.

Disposal

In case of a disposal of the materials, please bring them to your local recycling center. Do not use your personal bin.
Especially, the polyurethane binder shall not be poured into a sink, for environmental reasons and also because it solidifies in the presence of water.

Toxicity ?

Health

Numerous scientific studies were conducted on the potential impact end-of-life tyres products on human health. Most of the studies were focused on the use of rubber granulates in synthetic turfs, given that it is the main existing application where people are directly exposed to recycled rubber, on a regular basis. For the time being, they overall show that rubber granulates have no significant impact on human health. More informations and studies here

Environment

The environmental impact of rubber in synthetic turfs has also been analysed in several studies. One of the study was conducted in France: Environmental evaluation (Aliapur/Ademe/Tarkett, 2007).

Leaching

Some elements, like zinc, can leach into the rain water. However the measured concentrations in the percolates were well below the regulatory limit :

From an ecotoxological point of view, the nature of the percolates having passed through a 3rd generation artificial pitch are proven to be without impact on the environment, irrespective of the type of filling granulates.

VOCs emission

The emission of Volatile Organic Compounds (VOCs) was also assessed :

In conclusion to its study, the INERIS stipulates that the health risks associated with the inhalation of VOC and aldehydes emitted by artificial surfaces on pitches in outdoor situations give no actual cause for concern as regards human health.
