Mosswool regrows within twenty years

"Better production with sustainable addition to peat"

The first Mosswool factory is currently being completed and will be operational within this year. What is this new growing medium, and why is supplying company Novarbo Oy so enthusiastic about it? According to Pirita Luolamaa-Vollebregt, it’s a sustainable addition to peat, as the Mosswool regrows within a couple of years and the product can be composted.

Trying out the new product
“We want to test it in both research circumstances as well as real-life cultivation. That’s why currently crops are being grown on Mosswool at both Tomato World and Wageningen UR. After positive trials in Finland, I’m very excited to see what this will bring.” This says Pirita Luolamaa-Vollebregt with Novarbo Oy, focusing on the cultivation with this relatively new product.

Mosswool is made of sphagnum moss, which is harvested using a patented ecological method. Mosswool slabs are a combination of moss and peat, processed in airy cultivation mats that keep their shape throughout the cultivation. Afterwards, mats can simply be processed as green waste.

Regrow
“Beneficial of this nature product is that the living moss will regrow after harvesting”, Pirita explains. “The surface of the bog is not skimmed bare, so there remain plenty of spores to regrow new moss. After harvesting, the bogs return to their former state within a few years. Therefore this is a sustainable addition to peat.”

According to Pirita, Mosswool saves money for the greenhouse farmer, as waste costs are lower because used slabs can be composted together with crop residues. "But most importantly, Mosswool growing slab is the drop-in sustainable replacement to stonewool. EU regulations state that stonewool filled with living root mass may not be dumped in landfill. After one year of usage stonewool will be problematic waste, which does not burn or decompose. Mosswool solves this issue since it can be easily locally composted with the crop residues or recycled after use, which minimizes disposal costs”.

 

Better production
In 2016-2018, the company tested Mosswool with tomato and cucumber producers in Finland. Pirita shares their insights: “Growers have alternated traditional pressed peat mats and Mosswool for an optimal comparison. The results showed that Mosswool works even better and the product isn’t in need of a long buffering period. And just like stonewool, Mosswool keeps its shape during cultivation.”

Also LUKE, the Finland Natural Resources Institute, carried out comparison tests between stonewool and Mosswool with cucumber. Luolamaa-Vollebregt points out, “Mosswool showed a better production per sqm. This is because it has a buffering capacity for both water and fertilizer, balances pH and it has antiseptic properties.”

With regard to the company’s future plans, Luolamaa-Vollebregt says Novarbo is already looking forward to the end of 2019 to improve its presence in the Netherlands, Germany and Belgium. “I will assist them in this. I myself come from Finland and have been working in the horticulture industry in the Netherlands for more than 20 years. Since 2010, I run my own company in the Netherlands that exports flowers and plants to Finland. Import fits well and I feel very connected to the ecological value of this product”.
