Regular process checks by CCD: a sustainable and virus-free washing process for industrial clothing in greenhouse horticulture

In the greenhouse industry, it is essential to disinfect company clothing correctly to prevent infections by viruses such as ToBRFV (Tomato virus) or, for example, CGMMV (Cucumber virus). These viruses have already caused great damage worldwide and, once in the greenhouse, are extremely difficult to fight. Strict hygiene protocols, including the mandatory use of company clothing, are important measures. Nevertheless, standard washing processes for industrial clothing were found to be insufficient to kill these viruses. An effective approach is therefore crucial to keep the virus out of the greenhouse and prevent further spread.

The problem with standard washing processes

Standard laundry processes for industrial clothing are mainly aimed at removing dirt, stains and a hygienic end result. Nevertheless, these are usually not effective when it comes to killing off these types of plant viruses. In addition, the agents that are effective against these viruses in the greenhouse were found to be unsuitable for washing clothes. They degraded the appearance of the clothes, caused accelerated wear and tear and resulted in additional environmentally harmful wastewater.

A sustainable solution: a specially developed washing process

In his previous position, Peter Giezeman, one of the consultants at CCD, played a key role in developing a special washing process for greenhouse horticulture. This process, which is now used at many greenhouse farms, not only effectively kills viruses but also preserves the appearance of the company’s clothing. The system uses peracetic acid and is specifically set up on industrial washing machines.

By dosing detergents automatically and in the right amounts at different times, viruses are demonstrably eliminated even at a main wash temperature of 50 degrees. As a result, company clothing lasts significantly longer and consumes much less energy than traditional washing processes.

The importance of periodic checks by CCD

Although the washing process has been carefully developed by a specialist team and uses professional equipment, it is still crucial to check the operation regularly. This is where CCD comes in. As an independent specialist, CCD performs periodic process checks on site.

During these checks, the entire washing process is assessed and critical process parameters are tested using validated materials. In some cases, a CCD specialist can even make minor adjustments immediately to correct any deficiencies and restore the process to optimal operation. After each audit, the greenhouse company receives a comprehensive report, which always gives them full insight into the effectiveness of their washing process and the disinfection of their company’s clothing.

A sustainable and safe washing process for greenhouse farming

Thanks to CCD’s regular inspections, greenhouse farms can be confident that their washing process for their industrial clothing is operating optimally and meets the highest hygiene standards. These process controls not only guarantee effective virus control, but also help maintain the quality and durability of the clothing. This allows companies to focus entirely on their cultivation and business operations, with the peace of mind that the hygiene and safety of their work clothes are always in top condition.
