The current generation of controled-release fertilizer granules posesses a coating of traditional plastics in order to have a slow or controlled release of nutrients into the soil. This implies that with every granule used on the soil a small layer of plastics stays behind, finally turning into microplastics! In this way, tons of plastics enter into the soil every year ending up in the food chain.
Delft Solids Solutions has developed a new route to coat fertilizer granules with a truly biodegradable coating composed of 100% poly hydroxy alkanoate (PHA) coating that also displays a controlled release of nutrients similar to the traditional coated granules.
In this way, we prevent microplastics from polluting the soil AND we also work in accordance with European regulations that will prohibit the use of the traditionally-coated fertilizer granules !!
