The Van der Knaap Group takes a serious approach to sustainability and corporate social responsibility (CSR).

That is why we use organic, environmentally friendly materials. Coco is a perfect example of such a material. A palm tree produces about 100 coconuts a year, which means that we can describe it as a renewable resource. Every component of the coconut is used. The inner nut is processed for oil and charcoal, while the coconut husk is processed in the fibre industry. What remains once the fibres have been removed from the husk is known as coir. We use this by-product for the finer coco substrates, such as Knaap Elite. By cutting up the whole husk, we can create coarse substrates such as Knaap Profit and Knaap Maximum. Coco can be recycled and turned into a raw material for soil improvement. We limit CO2 emissions by transporting all of our coco products dry and in compressed form.

As well as taking care with the environment, we contribute to the society in which we operate.
We invest substantially in local projects in the countries where we produce. We also offer employees in production countries above-average wages and training facilities. Van der Knaap also takes an active approach to helping communities by building schools, wells and homes for the underprivileged.
