During the 'Vertical Farming, in or out?’ meeting on 14 October 2016, Rien Panneman of Staay Food Group announced that the company would be producing its own lettuce in a large vertical farm in Dronten from 2017. The new building is expected to be ready in mid-April 2017. The farm will be up and running by June 2017, according to Panneman. The meeting was organised by InnovationQuarter.

During his presentation, Panneman outlined why Staay Food Group has taken on a vertical farm project. "We have a factory in Dronten where we produce sliced vegetables and salads. The desire arose for more certainty, especially in the area of food safety. Another reason is local-for-local. At the moment, we source our lettuce for six months of the year from the Netherlands, and the other six months from Spain or Italy, so it’s not as fresh as it could be. If we can produce that in-house in the same place where we process it, we can guarantee sustainability thanks to lower logistical costs and reduced CO2 emissions. There are also other benefits, because there will be fewer foreign materials such as rocks, insects and even, in exceptional cases, frogs."

Clean product

"The retail market at home and abroad stresses that we must concern ourselves with a cultivation method which is completely in line with vertical farming," continues Panneman. “There are various benefits to vertical farming; lower energy consumption and water consumption, for example. We also see advantages in terms of plant protection and microbiology. Supermarkets are trying to distinguish themselves by setting maximum limits for pesticide residues. However, that is obviously not the only battle. We have done tests with Philips, and found that products grown under LED lighting are many times better than products grown in the open soil in bacteriological terms."
Continuity also plays a role. “With vertical farming, we obviously know exactly when to sow and when to harvest, and the quality to expect," said Panneman.


In addition to the demand from supermarkets, the cooperation with lettuce grower Deliscious and developments in Japan have inspired investments in vertical farming, as Panneman explains, "Consumer prices in Japan are much higher than here, enough to make it viable there, in contrast to the Netherlands. We contacted a number of partners for discussions; Philips, Rijk Zwaan, HAS Wageningen, CAH Vilentum University of Applied Sciences in Dronten, and development company Flevoland. We sat down with them round the table, and explained that we want to set up something unique in Dronten. We are now working hard on it. A completely new factory is being built, scheduled for completion in March/April 2017. The vertical farm area is now being engineered, and is expected to be operational in June."


Staay Food Group’s new Fresh-Care Convenience Centre covers a total of 27,000 m² of floor space. The main area consists of high-care and low-care rooms. The entire hall in which the vegetables will be cut and packaged will be cooled. This includes the vertical farm, a conditioned space where lettuce is grown hydroponically under LED lighting without daylight. A 70,000 m2 plot is available next to the factory, where phase 2 can be built. Panneman, “We will be rolling out phase two as soon as we feel confident about growing under LEDs, guaranteed costs, and quality levels."
However, the ambition goes beyond the creation of a state-of-the-art production facility. "The new building is also an auditorium, where lessons can be given. We will also train foreign students. That gives us, and our partners, an advantage of course."

Income model

The cost of growing prime lettuces in a vertical farm is currently double that of current methods of cultivation. "However, the advantages are obvious and this is something our customers, the supermarket chains, recognise," says Panneman. "In addition, the cost of the lettuce component is limited, so our customers will gladly accept a limited price increase. After all, they receive a higher quality, safe and sustainable product for their money, with which they can distinguish themselves from the competition."
Staay Food Group is already thinking about setting up vertical farming projects outside the Netherlands. Panneman says, "You see more and more local-for-local and region-for-region agriculture, which means that we will eventually lose a lot of our export markets in the future. I think we should respond positively. We have to maintain our knowledge advantage in the field of fresh food production, and create a new model for generating income. State Secretary Van Dam recently said, ‘Let's stop dragging commodities around, and focus on exporting chain and production knowledge.’”
Staay Food Group is willing to share new knowledge. “Ultimately, we will also benefit from this; we need people who know how to grow under LEDs, who we can put to work both in the Netherlands and beyond." To conclude, he says, "We are convinced that this will be a success story. Our customers are very enthusiastic, and next year we will be able to produce profitably from day 1."

On 14 October 2016, InnovationQuarter organised a meeting at Koppert Biological Systems with the theme ‘Vertical Farming, in or out?’. More than 90 representatives from the sector listened to speakers such as Martien Penning (Hillenraad), Arnold van Liempt (Philips) and Jasper den Besten (HAS) talk about the opportunities, threats, benefits, costs, opportunities and challenges of vertical farming. Rien Panneman from Staay Food Group announced that a large construction for a vertical farm project in Dronten was all underway.

Martien Penning from Hillenraad gave a presentation on whether vertical farming (VF) can become horticulture’s ‘KODAK Moment’. His answer was yes. He substantiated this with an analysis of the most recent developments in the US and Asia, where dozens of VF initiatives have been rolled out. The big question was: When will VF perform as well as or better than conventional farming in greenhouses? Cost, quality, food safety and delivery speed are all key criteria here. His conclusion was not whether VF is feasible, but where and when.

Arnold Liempt from Philips Horticulture LED Solutions gave an overview of the many international vertical farming projects currently underway or being implemented. His presentation also made it clear that many there are many different models of vertical farming; from vegetable gardens under glass to cleanroom factories. An example was shown of an in-store farm with LED lighting at Metro Group in Berlin. VF in the Netherlands is still limited to research centres (Brightbox, Grow Wise Centre and PlantLab), and the propagation of seedlings, such as at lettuce grower Deliscious.


Jasper den Besten of HAS University of Applied Sciences talked about which technological developments vertical farming might accelerate. He proposed that conventional greenhouses would remain important for growing vertical crops such as tomatoes, cucumbers, peppers and aubergines, while greenhouses with intermediate LED light could be seen as ‘The New Cultivation’. Just like Martien Penning, Den Besten noted that many technologies such as LEDs, sensors and robots are rapidly decreasing in price, and that this will accelerate the financial viability of VF projects, even though the cost of lettuce and herbs from VF is still considerably higher (2 to 8 Euros per kg) than those from a conventional greenhouse. On the other hand, VF projects can be better controlled in terms of colour, flavour and substances in plants. For example, the brix category of strawberries can be improved.
Ruud Kaarsemaker from Groen Agro Control discussed how nutrients could be used to control substances in plants. He said that the maximum possible returns are defined by the objectives, which might be dry matter content, substances in the produce, potassium or nitrate content, absence of residues or shelf life. The variety selection, cropping system (e.g. NFT) and recording analyses of nutrients can be used to achieve the desired objectives.

Vertical Pharming

‘Alternative Thinker' Peter Jens sees VF as an opportunity to grow medicines, and therefore prefers the term ‘vertical pharming’. According to Peter Jens, we have to look at consumers differently in order to decide if VF is a beneficial cultivation system.
After the presentations, it was the turn of those working in the field, represented by Priva, Vitro Plus, Rijk Zwaan, Certhon, Plantlab and Staay Food Group. The expectation of a number of experts was that vertical farming will soon be offering plenty of opportunities for some crops and segments (the luxury segment and specialty shops and restaurants). Many flower crops and vertical crops such as tomatoes are unsuitable at the moment, but breeding and other growing techniques may eventually offer opportunities. VF definitely offers perspectives for special segments and niches in the market, but it is not yet able to compete with conventional cultivation.

Staay Food Group

To everyone's surprise, Rien Panneman from Staay Food Group announced that a large construction for a vertical farm project in Dronten for the cultivation of lettuces to supply large supermarket chains was underway. The project involves cooperation with various partners (Philips, Rijk Zwaan) and knowledge institutions (HAS, Wageningen UR). This farm will be up and running no later than June 2017, which means that VF will soon be a reality in the Netherlands. Growing in climate cells is seen as clean and food safe, something which consumers are willing to pay more for.
Anne-Claire van Altvorst from InnovationQuarter looks back on a successful day, “Many insights were presented from various quarters, as well as opportunities in many market segments. The openness we were able to create with each other was an essential element for ensuring the positive atmosphere. It was a fantastic day, and looks like it will be repeated. What is true, especially after the eye-opener from the Staay Food Group, is that vertical farming is 'in'."
