This edition features the company BOL in our series “RHP Stories: Committed to Quality.” In this series, we highlight certified companies and invite them to share what RHP certification means to them and what it has brought to their business.
"Since 1999, all our raw materials and end products have been RHP certified. We use about 40 different raw materials and a similar number of fertilisers. With this we make 1000 different recipes, all under the RHP quality mark. The majority of our substrates go to professional growers of potted plants. We set high standards for ourselves, and our customers expect the highest possible quality in substrates from us. There is no higher certification than RHP, so this is the minimum level we want to meet."
"We carry out a lot of practical research ourselves and in this way we stay constantly up-to-date. RHP also conducts in-depth research. This allows us to broaden our knowledge, which we then apply in practice. A lot has changed in recent years due to the use of renewable raw materials. It is possible to acquire this knowledge independently, but that takes a lot of time. With RHP, knowledge developments go faster and we get new insights faster. This ensures that we reach a higher level of knowledge faster and can serve our customers better."
"As mentioned earlier, our customers expect the highest achievable quality in substrates from us. The RHP quality mark is then a necessity. You want to minimise any risk for your customers, and you do everything you can to do that."
"The RHP quality mark indicates that you meet the highest achievable requirements within our sector. That is of course what you strive for as a company. We are also proud that RHP has carried out major studies at our location in recent years. That means that RHP sees us as a professional and serious player."
"We are conducting small-scale trials with new renewable raw materials that do not yet have the RHP quality mark. Our vision for the future is that we need to expand our raw materials package to spread risks. A lot has happened in the past year, from shortages to wars. All this has influence. You don't want to be dependent on just a few raw materials. The broader the knowledge of raw materials and the greater the availability of different raw materials, the lower the risk."
"The cooperation with RHP has been very good from the start. We get along well with the people who work there and see the knowledge in the sector increase every year."
