C&M Kester has a large (rain) water collection capacity, to be able to cope with the large differences between wet and dry periods as much as possible.
The rainwater is collected in 3 basins, so that there is enough water available year round. No spring water is used. The cultivation floors are connected to a closed system so water and fertilizer can be recirculated. An ebb and flow system is used linked to a closed system. Here 100% of the casting water is recirculated. This way, there is no run-off to the soil. The duration that the water is on floors in the ebb and flow system is optimally set, depending on the need (according to the seasons), plants and pot size.
The water used for cleaning floors, windows and pathways is also collected, filtered and recirculated. Even condensation water from the nursery is collected and reused. C&M Kester does not discharge any water.
C&M Kester strives to preserve nature and improve biodiversity around the company
In order to preserve nature, the grass and weeds along the ditch sides are regularly cut and checked (pncr every month). When mowing the ditch edges, bird breeding sites are spared. Where ditch edges are collapsing, they are repaired as much as possible. The local municipal guidelines for the removal of trees are complied with. (felling permit, replanting etc.)
Any disturbance of game and birds shall be reported to the competent authorities.
Planting on the yard is well maintained in order to keep the company’s appearance as natural as possible.
Waste materials such as plastic, paper and cardboard are collected separately within the company and disposed of as soon as possible. Everything is kept as clean and natural as possible. All this to preserve the environment.
Employees are particularly alert to the presence of diseases and pests in the plants. Samples are taken weekly to test the plants. If any pest is discovered, first, efforts are made to deal with the problem in a ecological way. If this is not possible, only a limited amount of plant protection products will be used.
C&M Kester strives to raise awareness of energy consumption. Targets have been formulated to minimise energy consumption with methods to obtain this.
In 2009/2010, a completely new building (green label) has been erected in which a conscious effort was made to minimize energy consumption by equipping the entire greenhouse with a double movable screen cloth, sun permeable and blackout cloth, which should save a lot of energy.
The transport pipes and the manifold in the boiler house are insulated so that there is as little temperature loss as possible.
If cultivation permits, the use of the boiler is kept as low as possible and switched off as far as possible. The heating grid at the top of the greenhouse has been lowered further, thus minimising energy loss. A heat storage tank has been built for the new building, in which sufficient heat is stored for 24 hours.
