PROJECT DESCRIPTION
BACKGROUND
The demonstration-project is based on disinfection through a CO2-highpressure method. It is vital for commodities, half-products as well as end products in food and pharmaceutical industries. The CO2-highpressure method is an environmental oriented disinfection method and can be considered as a real replacement for CH3Br- and PH3-fumigation and other pesticide-chemicals for disinfection.The demonstration-project is based on disinfection through a CO2-high-pressure method. It is vital for commodities, half-products as well as end products in the food-industry. Also woodprotection can be made most adequately with this method. The CO2-high-pressure method is an environmental oriented disinfection-method and can be considered as a replacement for CH3Br- and PH3-fumigation and other pesticide-chemicals for disinfection. Within our demonstration project, CO2 being used as an inert gas, under high pressure, in an airtight pressure chamber, to expel the oxygen: vital to harmful vermin/insects. the maximum pressure used during disinfection will be 30 bar. The CO2-gas will penetrate into the insects, germs, vermin and their eggs, which will kill them. The final pressure-release will disinfect the total product finally including eggs. This guarantees 100% mortality on all insects, germs and vermin. The CO2-highpressure method is considered by TNO as the most reliable replacement for CH3Br. In the demonstrationproject containers are being gassed completely. It can hold 1 x 40 FT or 2 x 20 FT containers, per cycle. This avoids additional handling on arrival and departure for the treatment of the product. Our concept treats and disinfects the wooden parts of the container and/or wooden-packing material. The legal prescriptions for export to Australia and New Zealand require disinfection of wood-larve-germs. The consumed CO2-gas in this demonstrationproject is recovered within the chemical industry and will not give any increasement of CO2-emission. Our concept operates with a double pressure chamber. This will reduce the CO2-consumption by approx. 50%. Furthermore (after the processing): CO2 will be recuperated through our installation for at least 90%. Nowhere in the world a similar major unit has ever been build or tested. Therefore this demonstration-project is unique in the world.
