Our Wood Fibre for substrates, being a renewable raw material, is produced out of circular, European, PEFC certified wood. It is available throughout the year, and its quality is not influenced by weather conditions. Thanks to its low bulk density environmental impact of transportation is relatively low.
How we treat our Wood Fibre for substrates
The first thing that makes BVB Wood Fibre different from commonly used Wood Fibre is the type of wood that is used to create the fibres. We only use 100% pure hard wood logs from European spruce trees. This specific type of tree is used, because it provides wood with a strong fibre structure ensuring stability throughout the entire growing period. No branches, needles or left over wood is used in this raw material, because this can cause impurities in the end product.
In addition to the quality of the wood that is used to create BVB Wood Fibre, the production process of the fibres has specific steps that guarantee top quality as well. The Wood Fibre we use in our BVB Substrates products goes through four main steps which makes it different from commonly used Wood Fibre.
Step 1 – Steam treatment
By steam treating the Wood Fibres we not only make the material clean and safe to use, we also loosen the fibre cells to make sure we get the desired texture in the next steps of the process.
Step 2 – Grinding
By grinding the Wood Fibre we create a “woolly” texture exposing more surface area. This brings beneficial properties to the substrate.
Step 3 – Fluffing
After the fibres have been created we use machines to fluff the Wood Fibre. This way the fibres are loosened to improve uniform blending in the next step.
Step 4 – Mixing
The final step of using BVB Wood Fibre in our substrates is ensuring it is optimally mixed in with the other raw materials. We use modern mixing lines to ensure uniform blending of the different raw materials. If Wood Fibre is not adequately mixed in, it can form lumps with other raw materials, which can cause issues when used. The fibre lumps can heat up during the growing period, disturbing hydro dynamics and impeding root growth.
