Swiss technology giant Sidel has introduced a dry-decontamination technology for bottling beverages.
Sidel said the new Combi Predis/Capdis FMa technology decontaminates the preforms (the Predis) and caps during bottle closure (the Capdis).
The decontamination process is applied on the preform, which has a surface area that is ten times smaller than its blown bottle, instead of on the bottle itself and during closure; it uses hydrogen peroxide as a disinfectant.
The company claims that the process uses less water, chemicals and energy compared to the conventional wet bottle decontamination systems and the energy needed for the disinfectant takes advantage of the thermal conditioning of preforms.
The process eliminates the risk of chemical residue and the need for sterile water rinsing; due to the advanced decontamination technology the Predis is well suited for sensitive products like iced teas.
Françoise Raoul-Duval, Sidel vice president for sensitive products, said the expectations of beverages players globally are becoming increasingly focused on sustainability, product safety, flexibility and cost efficiency, which can be hard for sensitive products that need extra care.
The technology is already being used at a Refresco France plant, where Lipton Ice Tea drinks are bottled using 50% recycled PET for PepsiCo France.
It has enabled the plant to save about 1,700t of CO2 equivalent, 38,000m3 of water, 2.5 million kilowatts of energy and more than 400t of virgin PET every year, Sidel said.
Sterilant usage has also been reduced from 42t of reracetic acid (Peroxyacetic Acid: PAA) to 6.7t of hydrogen peroxide.
Recently, Refresco France, PepsiCo France and Sidel have been jointly awarded the Prix Entreprises et Environnement (Enterprise and Environment Awards) in France in the category of 'efficient and clean technology'.
