Van Woudenberg Tuinplanten B.V.

Van Woudenberg Tuinplanten BV is a family business based in Zevenhuizen. They have grown large, but in their customer approach they are people-oriented. In 1968 Van Woudenberg Tuinplant BV was started by Bert and Gerry van Woudenberg. It was a typical fruit-growing business from Zevenhuizen. In 1985 the nursery was hit by a fire and from that moment on the company was gradually continued as a garden plant nursery. That turned out to be the smart move. The percentage garden plants increased steadily since 1990 and eventually they were producing only decorative garden plants. With the arrival of the next generation, the growth of the company accelerated.

Maintaining the values that Bert and Gerry represented, the family business Van Woudenberg Tuinplanten BV has become a major player, producing a wide range of perennial garden plants, with cultivations in the Netherlands and Portugal. Because part of the product range is cultivated in Portugal, it is possible for Woudenberg to market the plants earlier than usual. The first species come to the Netherlands from March onwards. People within the company are very focused on good quality, go for lasting and long-lasting relationships with customers and do not immediately opt for the quick profit.

Sustainability

Water
No spring water is used. Rainwater is collected in basins, so that there is enough water available year round.

The cultivation floors are connected to a closed system so water and fertilizer can be recirculated. A recycling system is used on lava floors. Excess water is collected in silos and reused. A recirculation of 100%. This way, there is no run-off to the soil.

Biodiversity
Van Woudenberg Tuinplanten BV produces perennials on container fields. These perennials attract bees and butterflies. The nursery also houses hares, rabbits and pheasants. Therefore, no plant protection products are used that are not permitted under the current directives and legislation.

Historically there is 1 large tree where a kestrel comes to breed every year. So every year the nursery Van Woudenberg houses a nest with 4-6 young kestrel to admire.

Among other things, Van Woudenberg cultivates the Echinacea plant, which is used in a health care product of Dr. A. Vogel to maintain the resistance of children from 2 years of age. This product is called Echinaforce.

Climate
Concerning energy consumption and emission of gases regarding air pollution.
Van Woudenberg produces between 75 and 100 different species of perennials in different pot sizes. Energy consumption is particularly low as many plants are grown outside and the cultivation of plants in the greenhouse is cold grown. Only in exceptional cases heating is used in the greenhouse but this is only to keep the greenhouse frost-free. Other than that, they do not have any heating costs.

People

Within Van Woudenberg Tuinplanten BV, employees get the opportunity to develop themselves and to grow to a different position. If deemed eligible, employees could become part of the management.
All employees are treated equally. This also applies, of course, to men and women.

There is a freedom of religion within the company including the possibility to propagate it. Every employee has an employment contract and therefore has income security enabling them to provide themselves with a proper place to live.

Health

Did you know that flowers and plants have a healthy effect on people?

Plants provide air purification..
People breathe in air, take out oxygen and breathe out carbon dioxide. In the case of plants it is the other way around. During photosynthesis, plants remove carbon dioxide from the air and convert it back into oxygen. The amount of oxygen in the air is increased by the presence of plants, which makes breathing easier.
Air-purifying plants can absorb harmful substances from the air through their leaves. These harmful substances are then stored and broken down in the plant’s roots. These plants can also break down dirty odours, so they are actually natural air fresheners.
For the sake of clarity, every (indoor) plant produces oxygen, but not every plant also purifies the air. Air-purifying plants are e.g. the Spathiphyllum, Calathea, Hedera helix (ivy), Areca palm and the Ficus. For many plants we do not yet know to what extent they have an air purifying effect since they have not yet been tested.
Plants ensure a better concentration and a reduction of stress.
Plants create a relaxed and better atmosphere, also at work.. Plants make the workplace a more pleasant place to work.
Apparently there is even a relationship between the presence of plants and the productivity of employees.
Moreover, the presence of plants has a positive effect on the creativity and concentration of people.
Plants reduce the dryness of the air
The dust content and humidity in the house are strongly related with each other. The dryer the air, the more dust. This can cause symptoms such as a tickling cough, dry skin, headaches and irritated eyes. By watering plants, it finally evaporates again through the stomata in the leaves. Plants can thus increase the humidity of the air, which therefore benefits the air quality.
Plants provide a pleasant and warm feeling
Research has shown that plants are good for people in various (subtle) ways. They play an essential role in creating a pleasant, natural and quiet environment in which to move, work and/or relax.
Did you know that flowers too have a healthy effect on people?
Flowers can brighten up any room in a magical way. They give meaning to our emotions such as love, joy, comfort, compassion and sorrow. Flowers provide a relaxing effect on our constitution. They provide positive energy in the home and a warm feeling. In short, everyone is just very happy about that!

Innovation

The Dutch greenhouse horticulture sector is worldwide renowned for its innovative power. In order to be one step ahead of the competition from other parts of the world, people are constantly looking for better efficiency in the use of raw materials and space. This, of course, without compromising the (top) quality of the Dutch product.

The glasshouse horticulture sector in the Netherlands can cope with this rapid pace of innovation thanks to a strong relationship between research and practice. In addition, a great deal of knowledge is exchanged between the entrepreneurs in order to make progress together. The flower auctions are a good example of this as one of the largest cooperatives in the world.
Below we describe a few examples of this innovative power.

Biological control and integrated pest management
In order to minimise the use of pesticides and to find a better balance between parasites and their natural enemies, natural enemies of the parasites are used in the greenhouses. Thanks to the intensive exchange of knowledge between the growers and their suppliers, growers are increasingly able to produce a top quality product with organic solutions.

Combined heat and power (CHP)
Combined heat and power (CHP) is a large engine, originating from the shipping industry. Only it has been converted to run on natural gas. The efficiency of this motor is higher than traditional gas boilers. These engines drive a generator that generates electricity. This electricity is used in the company’s own nursery or is supplied back to the public electricity grid. The ‘residual heat’ produced by the engine is used to heat the greenhouses. After cleaning, the exhaust gases can be used to provide the plants with CO2. All in all, these motors provide an efficiency that can be up to 20% higher than the traditional method of heating (gas boilers).

Geothermal energy
Geothermal energy is used for this type of energy. A drilling tower is used to drill a well to a depth of 2-3 km. At this depth, water of more than 80 degrees can be ‘collected’. This heat is used to heat the greenhouses and then the cooled water is returned to the soil via a second source. It is expected that these sources will be able to continue to produce sufficient heat, even longer than the life of a greenhouse.

Drilling the well is an enormously expensive investment. In addition, there is a great risk that the drilling will ‘fail’. By working together with each other and with governments, in the Netherlands we are able to gain experience with this way of heating greenhouses sustainably.

Water purification
Plants need water and nutrients to grow. More and more nurseries are making use of the reuse of drainage water. This is water that is collected before it disappears into the subsoil. This ‘drainage water’ still contains many nutrients that can be used by the plants.
By reusing this water and mixing it with clean water, less fertilizer is used.
However, the drainage water also contains some ‘wrong substances’. The content of these wrong substances determines how much water can be reused. The application of new techniques creates opportunities to filter these ‘wrong substances’ out of the water.

Diffuse glass
In new constructions, more and more growers are opting to cover their greenhouses with diffuse glass. Diffuse glass ensures that light is distributed much more evenly across the crop without any shade or light spots. This leads to a more even greenhouse climate.
Temperature and humidity can thus be controlled more accurately, which means, for example, that the opening of the air windows can be limited, which leads to lower CO2 emissions.

LED lighting in greenhouse horticulture
A new innovation in horticulture is the use of LED lighting. This lighting is not comparable with LED lighting used in consumer use. In the horticultural sector, the lighting is produced by ‘power LEDs’ and therefore much higher. The major advantage of these ‘power LEDs’ is related to sustainable business practices: energy savings compared to high-pressure sodium lamps (orange-coloured lighting). This saves more than half of the energy.
Another major advantage is that when using LEDs, crops can be better controlled using the different colours in the light. This is in favour of a better growth and a higher quality of the product.
