Our Hortifibre is a wood fibre produced nationally in the Netherlands. Hortifibre is produced from wood chips, originating from unprocessed tree trunks. To produce our wood fibre, wood chips are subjected to high mechanical pressure at a high temperature. Temperatures of up to 100 degrees Celsius are reached during this process, creating a hygienic product free of plant diseases.
Hortifibre, our own high-quality and RHP-certified wood fibre, is often used as a component of potting soil. It is a sustainable raw material that also has specific, positive properties. Adding wood fibre to a mixture creates an airy structure. When used in potting soil substrates, a supplementary input of nitrogen fertiliser is often added during production or mixing to compensate for nitrogen immobilisation during cultivation.
Our Hortifibre is one of the circular raw materials that is widely used in our sustainable substrates. It is a wonderful, versatile and renewable product of local, Dutch origin.
Insight into sustainability and eco-footprint
The themes of sustainability and environmentally-conscious cultivation are gaining traction throughout the horticultural sector. To support growers in this transition, all our substrates are categorised into a sustainability class. This class gives our customers continuous insight into the sustainability and circularity of a substrate and the corresponding properties. This classification system not only aims to offer CO2 and peat-free substrates, it also examines the origin and type of organic raw materials and fertilisers.
Four different classes are used: A, B, C and D. The sustainability class of a substrate is determined based on a set of pre-defined standards. By taking these criteria into account when formulating a substrate blend, we can produce a product with the desired sustainability class.
The table below shows the different classes and the applicable criteria ranging from the peat percentage to increasing use of circular raw materials.
A Class
- 100% Peat free
- At least 50% green raw materials
- Maximum 35% mineral raw materials
- No inorganic fertilizers
CO2 Footprint Class A
(<60kg eq/ENm3)
B Class
- 100% Peat free
- At least 15% green raw materials
- Maximum 35% mineral raw materials
CO2 Footprint Class B
(<60kg eq/ENm3)
C Class
- Maximum 65% peat
- Exclusively RPP peat
CO2 Footprint Class C
(50-150kg eq/ENm3)
D Class
- More than 65% peat (unlimited)
- Exclusively RPP peat
CO2 Footprint Class D
(70-350kg eq/ENm3)
