95% of the rainwater from yard and roofs and 100% of the water from processes within the company is collected in a water storage facility under own control. So nothing ends up in the surface water. The collected water is used for various applications within the company, such as casting water for growing the product, flushing sanitary facilities, process water and rinsing bulbs after harvesting. Rainwater is actually used for everything, except for human consumption. For the cultivation in the greenhouse, computer-controlled water is given according to the product’s requirements, in order to use a minimal amount of rainwater and fertilizer. The water and the tank are disinfected with chlorine and hydrogen peroxide as these agents are biodegradable. Climate cells are cooled using the cold from ground water instead of energy, that is often used in conventional cooling.
Thanks to condensing boilers the residual heat from waste gases can be utilized. All tractors in the company are equipped with clean engines with ad-blue technology.
All packaging waste is cleaned and pressed if necessary. The pressed material is offered separately for sustainable recycling.
In order to prevent breeding meadow birds from being disturbed, employees working on the field pay attention to the various “natural movements” of the birds in the field. This way, employees can work around their nests.
When tulips are grown on the field, a crop-free zone of at least 0.5 metres is maintained along water edges in order to prevent plant protection products from entering the surface water.
For bulp production in the fields, only a few crop protection products are used, but during the production from bulb to flower no plant protection product is used at all. Ruiter-Wevers sustainable way of growing is therefore appreciated as particularly good by the accredited organisations issueing certificates.
The greenhouses are equipped with the most modern climate systems and energy screens. By mixing outside air with air from the greenhouse, a good climate for the tulip bulbs is created in a sustainable way. The fully automated container system on which the tulips are grown ensures optimal greenhouse utilisation and minimal energy requirements per tulip.
