The increasingly sustainable production of the products is a continuous priority. At an early stage (in the 90’s) the company started using CHPs (co-generation of heat and power). This means that the gas, which has been used for many years to heat the greenhouses, is used more efficiently. Electricity is generated when the gas is burned. The heat and CO2 released as a result of this process is used for the cultivation of the plants.
The next step is currently being considered. Solar panels have been installed for this purpose and new techniques are being examined.
The use of plant protection products has been significantly reduced over the years. It also remains a major challenge to continuously improve this. The aim at the locations in Oosteind and Prinsenbeek is to achieve complete organic control by 2018.
All in all, continuous steps are being taken to make growing ever more sustainable and to continue to provide consumers with attractive products in the future. This is what Kwekerij J de Groot does every day.
Three water sources are used:
1 Rainwater: Rainwater collected on the glass roof of the greenhouses is collected in water basins.
2 Groundwater: When there is a lack of rainwater, we use a water pump.
3 Ditchwater: If the above sources are not sufficient, ditch water will be used.
Plant protection agents
Chemical control against pests, disease and weeds is minimised. It is being used less and less and less, but unfortunately we cannot yet prevent it altogether. At the site in Prinsenbeek, 95% of the control is already organic.
The plants are grown in a mixture of peat and coconut fibre.
99% of the waste is recycled. The following waste streams are currently being separated: Paper/cardboard, plastic, green waste, glass, pottery/trays and residual waste.
A registration system is used, to provide insight into how we score in the field of energy, fertilisers and crop protection products. Nursery J de Groot is also in possession of various certifications from the officially accredited organisation MPS.
Trucks with a Euro 6 engine are being used for transport. Since 2016, the roofs of some of our barns have been equipped with solar panels. In addition, new technologies to reduce the use of fossil fuels are constantly being considered.
