Water recirculation: cost efficiency and sustainability go hand in hand

By: Jerre de Blok

Many will recognize this: you keep going through certain routines until you run into a wall. Only then you realize that things can or must be done differently. This is often also the case when dealing with water in greenhouses. It is therefore a good idea to already take into account developments that may influence your choices. Regardless of whether these are driven by costs or sustainability. In this blog, Jerre de Blok, production manager at Ridder, will show you how cost efficiency and sustainability for water recirculation go hand in hand.


As a grower, you want to keep your company running and that is a challenge in itself. As a result, you do a lot of things because you have always done it that way, without really thinking about it. But that doesn't mean you can't do certain things differently or better. Also, in the field of water treatment. In many cases, growers only choose drain water recirculation when they are confronted with a certain problem or challenge. Some choose it to be more cost-efficient, others to be more sustainable. But if you look closely at the developments in horticulture and take the time to prepare for them, you will discover that cost efficiency and sustainability are inextricably linked.

Efficient use of water and fertilizers

For example, take a look at the recent price increases of fertilizers. These are partly dependent on energy prices. As a result, you can suddenly be confronted with high costs. Or what about those drier summers when your water supply is suddenly no longer sufficient. Wouldn’t it be a waste if you just throw away all your drain water in this situation? These developments force you, as a grower, to make smart choices to ensure that you have sufficient water available and production costs do not rise too high. By growing on substrate and actively recirculating water in the greenhouse, you can use water and fertilizers more efficiently. This results in cost reduction on the one hand, but also in making business operations more sustainable on the other.
