Fa Freek vd Velden uses rainwater and osmosis water. Osmosis water is water purified from all accumulated contamination by reverse osmosis.
All water is first purified and then given to the plants. This is done by means of an ebb and flow system. The water is used very sparingly. The water that is not absorbed by the plants is collected again, purified and reused.
The water consumption has no influence on the drinking water supplies in the region.
In order to preserve nature, the grass and weeds along the ditch sides are mown or manually removed and sprayed with non-harmful agents. When mowing the ditch edges, bird breeding sites are spared. No unnatural or harmful substances are discharged into the ditches. The system is completely closed. The residual water is first cleaned before it is discharged into the sewerage system.
Employees are particularly alert to the presence of diseases and pests in the plants. Samples are taken to test the plants. If any pest is discovered, first, efforts are made to deal with the problem in a ecological way. That is to say, through the use of natural enemies. If this is not possible, only a limited amount of plant protection products will be used. These means must be easy to combine with biological means.
The greenhouse is equipped with a modern climate system, set up for optimal use of the recovered heat. By working with energy-efficient screens (3-double cloths) and blackout cloths, the heat remains inside and light emission is prevented. This reduces the use of fossil fuels (natural gas, oil, etc.). The climate can be regulated per department according to the needs of the plants present there.
Energy is partly generated by a CHP (co-generation). The excess energy they generate, is returned to the grid.
Waste materials such as plastic and paper are collected separately within the company and disposed of as soon as possible. In short, everything is kept as clean and natural as possible. The company collecting green waste processes it into compost, which ultimately results in a reduction of gas emissions. All this to preserve the environment.
