Quality Standards
At KLANZ, quality comes first at every step of our production process and in the selection of our raw materials. Our goal is to produce mineral substrates and fertilizers of the highest quality for indoor and outdoor greening.
The first step is the selection of raw materials. We only select the best raw materials to manufacture our mineral substrates. The mineral base materials must have an optimal structure and composition so that they are structurally stable in the long term and ensure long-lasting greening. When selecting our aggregates, we only use washed pumice from our own group of companies. During the washing process, By using state-of-the-art technologies and a team of experienced specialists, we ensure that our mineral substrates are processed gently. This guarantees not only their effectiveness, but also their durability and their ability to support healthy plant growth.
A particularly important aspect of mineral substrates is that they have a very low proportion of fines and elutriable content. the pumice with a high air pore volume is separated from the heavy, low-quality pumice and impurities are washed away. The lava used is a particularly “light lava”. This form is characterized by an extraordinarily largepored surface, which gives the lava a high air pore volume. Our production processes are designed to preserve the natural properties of our raw materials in the best possible way.
At KLANZ, we continuously strive to maintain and monitor our quality standards. Every step of our production process is subject to strict controls to ensure that our customers always receive their products in the usual KLANZ quality. Our substrates are tested by LUFA Nord West and examined for suitability in accordance with the Indoor Greening Guidelines of the German Landscape Research, Development and Construction Society FLL. Our granular NPK fertilizers containing zeolite are also subject to regular quality controls. The fertilizers combine the positive properties of their organic components, such as humic substances, malt culm granules and high-quality fine zeolite to improve soil structure and nutrient storage and to regulate the pH value. In this way, the fertilizers achieve a significantly higher cation exchange capacity to activate the full extent of their positive properties. At KLANZ, we endeavor not only to offer first-class products, but also to build a partnership with our customers based on trust, integrity and the joint pursuit of the best possible solution.
