About GreenMatter

Since the turn of the millennium, many artificial grass pitches have been laid, but too little thought has been given to how to deal with the pitches to be replaced. What is the state of the disposal, the waste stream, the recycling of the fibres, the backing and the infill? With the recent media attention, we can conclude that this has fallen short and that valuable raw materials have ended up in a grey area. However, the reuse of artificial turf in a responsible and circular way is possible! That is why two companies have joined forces and taken the lead in recycling material from artificial grass pitches and processing the fibres into new products on and around the sports pitch. With this website we hope to give you a good impression of our 100% circular approach.

Our mission is to convert the waste from artificial grass pitches into circular raw material streams by manufacturing recycled products. We are currently initiating two raw material streams: the artificial grass fibres and the SBR infill from old worn-out artificial grass pitches. Due to an extensive portfolio of sustainable artificial turf and rubber products for various purposes, there is plenty of choice to make the worn-out artificial turf pitches come back in a circular way.


To convert waste from artificial grass pitches into a circular raw material stream by developing and manufacturing recycled products.


We are keen to respond to the circular issues surrounding artificial grass waste in order to make a continuous difference as a provider of circular solutions.

The GreenMatter timeline

Period 1976 - 2028

Since the turn of the millennium, many artificial grass pitches have been installed but too little thought has been given to how to deal with the pitches to be replaced. We can conclude that this has fallen short and valuable resources have ended up in a grey circuit.


Period 2018 - 2033

After the advent of good recycling facilities, it appears that recycling and reusing artificial grass in a responsible and circular way is indeed possible! GreenMatter B.V. has taken the lead in reusing recycled raw materials from worn-out artificial grass pitches by processing them into products for on and around the sports field.


Period 2033 - 2050

Our mission to convert the waste from artificial grass pitches into a circular raw material stream by manufacturing recycled products where we ultimately strive for a 100% circular (sports) environment.
