In response to the increasing demand for renewable raw materials by various stakeholders, Bol Peat has expanded its range with composted tree bark.

TerrAktiv® bark humus from Bol Peat is composted tree bark, locally sourced from untreated spruce and therefore a homogeneous and safe ingredient with positive properties. The fermentation process is carried out according to strict German RAL standards and forms the basis for a very safe raw material. The route to RHP certification has also been started and during the certification audit, which can take place from February 2022, it will be assessed whether the product meets the applicable standards of the RHP quality mark.

The product shows extremely positive cultivation results, as evidenced by the intensive cultivation trials that have been carried out in recent years. TerrAktiv® bark humus can be used in substrates in addition to peat, coir and GreenFibre® wood fibre.
