Ozonisation is based on the conversion of stable oxygen (O2) from air to unstable ozone gas (O3). The ozone gas is produced by an ozone generator in the greenhouse. Ozone is injected directly in the drain water and induces oxidation of microorganisms (fungi, microorganisms, and viruses) and organic matter […]

    The Phytobac system is a system on which crop protection equipment can be cleaned and water with chemical residues can be caught and cleaned, rather than leaching it into the environment. The spraying equipment is placed on a grid, underneath the grid a collection tank is placed. The cleaning water that washes chemical […]

Photocatalytic oxidation (PCO) is a rather new technology in horticulture. It can be applied to i) disinfect water, ii) remove both organic and some inorganic pollutants, iii) improve color, smell and taste of water flows, and much more. In PCO processes, inert, non-toxic, inexpensive catalysts titanium oxide (TiO2) are used in combination with oxygen (from […]

For environmental reasons, it is necessary to reduce emissions of plant protection agents (PPA). Emissions must be virtually zero in 2027 at the latest (EU Directive 2000/60/EC). In some countries legislation forces horticulture to have emissions reduced considerably well before that date (example NL 2018). The first (and most effective) measure to reduce emission should […]
