Marco Zevenhoven has 34 years of working experience at RHP, the knowledge centre for substrates. RHP also manages and develops the quality mark RHP for raw materials and growing media for professional horticulture. The RHP quality mark is all about safety and quality and is considered the world’s most stringent quality standard for the growing media industry. For years Marco has been technical advisor for producers of growing media and suppliers of raw materials. He knows the products and processes in the entire chain of the growing media industry. He has visited hundreds of locations all over the world. He coordinates various international product groups that are active within RHP. And he is partly responsible for the requirements that RHP sets for the products. Marco also plays a role in the raw materials transition. Due to the increasing use of renewable raw materials, the properties of growing media will change significantly in the coming years. RHP is working on extensive research into the properties of (new) raw materials and their interactions in growing media.
Greener urban environment through circular economy
Meadows and nutrient recycling increase the diversity of the built environment above and below ground The debate around nutrient recycling in Finland often focuses heavily on the countryside and agricultural recycled fertilizers. However, the nutrients recycled in the growing media also end up back in the built environment. As more and more natural meadows or green roofs are added to cities, biodiversity will also increase.
Fire at Kekkilä-BVB´s Grubbenvorst production site – situation under control / Brand in fabriek van Kekkilä-BVB in Grubbenvorst – situatie onder controle
On Sunday the 15th of May there was a fire at the bark department on the Grubbenvorst site. Factory was not working at the time of the accident and there were no people injuries. One building and some machinery were damaged. The cause of the fire is being investigated. The production can continue on the site and at the moment it seems that all customer orders can be met with minor delays, if any. Although it seems very unlikely that growing media materials were impacted, careful quality assessment will be done in any case. We wish to thank the local fire department and our safety personnel for the quick actions taken to prevent and further damage. -------------- Brand in fabriek van Kekkilä-BVB in Grubbenvorst - situatie onder controle Op zondag 15 mei jl. is er brand uitgebroken in de schorsafdeling van de fabriek in Grubbenvorst. Op het moment van het ongeval was de fabriek niet in bedrijf en zijn er geen gewonden gevallen. Een hal en enkele machines hebben schade opgelopen. De oorzaak van de brand wordt nog onderzocht. De productie kan worden voortgezet en op dit moment lijkt het erop dat alle bestellingen van klanten kunnen worden afgehandeld met een kleine vertraging, als die er al is. Alhoewel het zeer onwaarschijnlijk lijkt dat grondstoffen werden aangetast, zullen er zorgvuldige kwaliteitsbeoordelingen worden uitgevoerd. We willen graag de plaatselijke brandweer en ons veiligheidspersoneel bedanken voor de snelle acties die werden ondernomen om verdere schade te voorkomen.
The story of circular substrates
The circular economy and sustainability are terms that are used by many companies repeatedly, interchangeably, and occasionally without real-life examples. With that in mind, we thought it was about time to tell the story our circular substrates in Finland, from start to finish and back again.
