Silvadec obtained ISO 50001 energy certification in 2022 thanks to the implementation of concrete actions aimed at reducing our energy consumption and consequently, our carbon footprint.

Our wood composite products are non-harmful to the environment and to the health of the end user. In particular, their emissions of volatile organic compounds (VOC) are very low.
