Den Ouden Organic

At Den Ouden Organic we take in more than 450,000 tons of green residual flows such as wood, grass and leaves every year. We process this at thirteen production facilities in the Netherlands into circular solutions for the potting soil and substrate sector, agriculture and horticulture, public space and the energy sector. Some of the woody flows are also used to generate green energy. In this way we contribute to the energy transition.

With our products and services we not only make public spaces climate-proof, but we also contribute to the transition to less peat use for the potting soil and substrate sector and create healthy soil.

• We have years of experience in producing substrates that are suitable for climate-adaptive design of growing areas and are a reliable partner in designing public spaces as effectively and sustainably as possible.
• With three processing locations for RHP certified compost, eight for Keur certified compost and two for Vlaco certified compost, we are the market leader that produces various types of circular, peat-replacing raw materials for potting soils and substrates.
• We increase soil fertility and stimulate plant growth with high-quality, circular soil improvers.

Innovation

At Den Ouden Organic we are a pioneer when it comes to the development of soil improvers. We keep a close eye on the market and are able to accurately meet social needs with our products and services. With our own in-house laboratory, we can analyse, test and develop new product innovations and also refine existing products.

Advice and project development

We have been specialists in soil improvement for over 75 years. With these years of knowledge and experience, we provide advice and develop projects from A to Z. Together with our customers, we look at what their challenges are and provide appropriate advice based on the situation in question. A good example of this is that we contribute to the development of the King Salman Park in Saudi Arabia with advice on improving the soil quality on site. We also coordinate the composting process there, monitor the quality of the compost and advise on the use of machines.

Transport and equipment

We have a hypermodern fleet of vehicles and machines that we not only use for our own projects and processing processes, but we also make available for the transport of green residual flows for third parties or for use at other project and processing locations. We are actively working on making our equipment more sustainable and from 2024 we will collect green residual flows with a fully electric crane truck combination.

Frequently Asked Questions

• Can I collect compost myself at one of your locations with a garbage bag or mortar bucket?

It is not possible to fill a mortar tub or garbage bag yourself. For safety reasons, it is not permitted to leave your car on the site. That is why it is necessary to come with a trailer and load it with the loading shovel.

• Can you also deliver products on location?

Yes, delivery can be made on location by truck upon consultation.

• How do I use compost?

Compost can be used as a soil improver by applying it directly to the soil and working it in lightly with a rake or hoe. The use of compost improves soil structure, increases the water and air permeability of the soil, reduces the need for fertilizers and chemicals, promotes the growth of healthy plants and helps suppress weed growth.

• How much compost do I need?

This depends on the size of the surface on which the compost is spread. Take into account 1 cubic meter of compost for 25m2 of surface area.

• When are you open?

Every day from 7:00 AM to 12:30 PM and from 1:00 PM to 5:00 PM. With the exception of Saturdays, Sundays and public holidays.

• Is the compost free of weed seeds and pathogens?

Because a high temperature is reached during the composting process, viable seeds and pathogens are killed. However, compost is never weed-free.

• Can I also pay with cash?

No, payments can only be made via PIN or invoice.
