Oonly Tisztán Víz Kft. established a plant for filling refillable plastic bottles in PannonhalmA

According to the information, after the end of the refilling cycle, refPET bottles are again made from the raw material following recycling. With this solution, the life cycle of a bottle is longer than that of single-use PET bottles.
A single replacement bottle ensures the consumption of 37.5 liters of water during the 25 refill cycles, which means that more than 80 percent less plastic is used during the entire life cycle than in the case of a single-use PET bottle.

Oonly’s refillable 1.5-liter mineral water bottling plant has an annual production capacity of more than 50 million units.
After exchange, the replacement bottles are delivered to the factory, where they are cleaned at high temperatures and subjected to a sterilization process, and then refilled with mineral water.

The specialty of Oonly mineral water is that it has a high metasilicic acid content of 33 milligrams per liter and a natural magnesium content of 54.5 milligrams among Hungarian mineral water brands, they wrote.
