Battery collection safer, thanks to sauerkraut
UN certified packaging as a collection vessel for spent batteries was one of Stibat’s (Stichting Batterijen = Dutch Battery Foundation) main requirements. An additional requirement was that gases could escape from the collection vessel. CurTec applied a piece of historic knowledge: its experience with packaging in the sauerkraut industry.
The cooperation between Stibat and CurTec goes back more than 10 years. On behalf of the producers and importers of batteries, all spent batteries must be collected, sorted and recycled. At the time, Stibat was looking for an alternative packaging for their paper mâché drums for collecting spent batteries. Gert-Jan van Huuksloot, Project Manager Business Development & Strategy, is confident about the cooperation: “CurTec provides a safe collection method and contributes with excellent solutions.”
Knowledge of sauerkraut
After collection, spent batteries must be transported in UN certified packaging. The ADR (UN regulation for the transport of hazmat on the road) requires this. Gert-Jan: “In order to comply with legislation, such a packaging must meet two criteria. Firstly it must bear a UN mark and secondly, gases must be able to escape from the packaging without affecting the strength and structure of the collection vessel.” CurTec’s 52 litre total opening drum offered the solution. Filled with 90 kg of batteries, it passed all tests successfully.
“However, we were still facing the challenge of gasification. We looked at various possibilities with valves. Our account manager at CurTec finally found the solution: leaving out the water tight gasket. This was exactly the alteration we needed to achieve gasification”, says Gert-Jan. CurTec tested the packaging again, this time without the rubber gasket, and it proved to be successful. The solution of removing the gasket appeared to originate from the time when CurTec drums were used in the sauerkraut industry. Gases also accumulated in drums filled with sauerkraut.

Stibat is also facing new developments in the battery collection market. For example, the collection and transport of special lithium batteries, often used in electric bicycles ( > 500 grams, > 100wh), require a special approach. Again, Stibat has chosen a UN certified collection vessel from CurTec for the collection. Gert-Jan: “In future, these drums will be placed in specialised locations. They will be equipped with different coloured lids so we can easily identify its content and control safety.”
