Dispose of gas bottles in compliance with regulations and safely

Naturally, the strict legal rules and regulations for pressure vessels are also to be applied in the case of disposal. Gas cylinders are usually not completely empty, even if no usable content is available. Disposal involves a residual risk, which requires a correct procedure if no offense is to be committed.

Termination or interruption of the exchange

Those who use gas bottles usually enter into an exchange and rental system. The once purchased first gas cylinder serves as a barter object for the following. Barter dealers like petrol stations hand out a new one only when the old empty gas cylinder is handed over.

A barter or a dealer is always legally authorized, one
to accept the returned gas bottle without handing over a new one. However, there are cases where one has expired or has exceeded its shelf life and the original place of purchase is unknown or far away.

Reasons for disposal

As a general rule, the operator of the exchange system is obliged to check the condition of the gas cylinders and to remove defective units from circulation. In this way, disposal cases for the lending buyer usually fall away. The reasons for having to finally dispose of a gas cylinder are:

  • Conversion of a technical system such as a heater
  • Relocation and change of location of the lender
  • One-off and temporary needs, such as welding or holiday bottles

Trader or Specialist

Gas traders such as petrol stations, camping equipment stores or hardware stores are in most cases connected to the deposit system of the barter industry. When taking back the gas bottle, the donor receives back the deposit paid at the time of purchase. If the gas cylinder is damaged or if no dealer agrees to take it back to you, you must go to a specialist cleaner.

The world market leader for gases, Air Liquide, based in Düsseldorf for Germany, disposes of all compressed gas cylinders in every condition. According to this, the adoption centers distributed throughout Germany comply with the statutory provisions of the Closed Substance Cycle Act and / or the Waste and Hazardous Goods Act. Some regional waste disposal companies offer the same services.

Procedure for professional disposal

In addition to fuel and liquefied gases such as butane and methane, helium cylinders and oxygen cylinders also fall for disposal. Approved and certified disposal companies offer the following range of services:

  • Assessment and testing of gas cylinders before transport
  • Detecting and identifying unknown content
  • Inspection of valve and outlet openings from damage
  • Preparation of legally required written documentation
  • Professional removal if necessary in pressure-resistant protective containers
  • Environmentally sound disposal and / or recycling of components, shell and contents

Dumped metal scrap

A special case of disposal can be created by professional residual emptying. In particular, for regular users of multiple gas bottles as obtained in scientific laboratories or some types of craft businesses, this type of disposal may be more advantageous. The old gas cylinders are emptied in accordance with the law and documented by valve dismantling or drilling. The "residual bottle" is then metal scrap.

Tips & Tricks

Even if you turn on the valve of your old gas cylinder for a long time, the bottle is legally not considered to be empty and often it is not.
