RHP certified for many years
In the professional horticulture sector, strict quality standards for crop substrate are crucial. Factors such as water uptake, pH, air content and nutrients play a key role in a successful crop. The RHP (Regeling Handelspotgronden) quality label provides assurance that these standards are always met, and
Copertiz has been a proud holder of this label since 2016. This applies not only to the production sites in the tropics, but also to our locations in Belgium and Europe. With this label, we guarantee substrates of the highest quality, specially developed to meet the requirements of modern horticulture.
First coir producer with HORTICERT certificate
In Germany, sustainability is at the heart of horticulture. The HORTICERT certificate measures CO₂ emissions and social impact of substrates, with clear criteria for environmental friendliness.
Copertiz is proud to be the first coir producer to obtain this certificate. It confirms our commitment to sustainable production and social responsibility, offering customers an environmentally conscious alternative.
