Along with gas cylinders, gasoline stoves and spirit burners, camping stoves with gas cartridges are among the most widely used fuels for mobile outdoor stoves. Gas cartridges come in different sizes, and weigh different amounts accordingly. Common sizes here are ca. 100 g as the smallest cartridge, ca. 230 g as the middle gas canister and ca. 450 g as the upper end of the bar.
The cartridges are usually filled with a liquid mixture of butane and propane. These two types of flammable gas have the advantage of remaining liquid even at low compression. This means that the cartridges do not have to withstand high pressure, and the mixture in the gas cartridges is therefore much less dangerous to transport and handle. The liquid gas in the gas cartridges for camping stoves is often identical to the mixture in commercial lighters.
Screw-in cartridges and cartridges for camping stoves
Depending on the construction of the camping stove, only the appropriate piercing or screw cartridges can be used for cooking. Especially with older stoves, the piercing cartridges are punctured when connected to the stove. The seal on the stove ensures that the gas cannot escape unintentionally. Once the cartridge has been pierced, it must not be removed from the stove until it has been completely used up and emptied.
This problem does not exist with screw-in cartridges. Equipped with an integrated valve and a screw thread, the gas cartridge can be unscrewed from the stove and screwed back on again for cooking as often as desired. Gas stoves with screw-in cartridges can be disassembled for transport in a backpack, bicycle or car and stored in a space-saving manner. There is also no danger of gas escaping from the cartridge during transport.
Transportation of gas cartridges in the car
Transporting gas cartridges in a car is usually possible without any problems. For safety reasons, the cartridges should not be heated above 50°C. Since the 50° C temperature is quickly reached on hot days in the car, it is better to pack the cartridges in the trunk so that they are protected from direct sunlight. If you don’t store your gas cartridges directly behind the windshield, you don’t have to worry about the safety of your cartridges.
If for any reason the cartridge becomes too hot, it will usually start to inflate and expand at the bottom. However, a gas cartridge can only become truly explosive if it is placed directly in the fire and ignited when it bursts open. In this respect, gas cartridges are very safe and can be used without concern.
For longer journeys, it is certainly better to unscrew the cartridges briefly when transporting them in the car. the cartridge does not unscrew by itself when driving, but if the valve on the stove is not closed tightly or comes loose easily on a bumpy road, gas could flow into the car. Therefore, it is better not to take any risks, unscrew the cartridges and store them in a cool and light-protected place.
Transport of gas cartridges in the airplane
A real trekking idyll – thanks to gas stoves!
Neither in hand luggage, nor in checked luggage may gas cartridges be taken on an airplane trip. Incidentally, this applies not only to gas cartridges, but also to also for all other flammable gases and liquids. gasoline for the gasoline stove or spirits for the spirit stove are therefore absolutely taboo in the flight luggage. The only exception that is usually allowed when flying is a single (gas) lighter, which must be kept on the body (but it must not be kept in the luggage carried). storm lighters, gasoline lighters and refill cartridges for lighters of any kind are generally prohibited.
What is forbidden in the gas cartridges and fuels without exception, does not apply to the stoves themselves. Whether gas stoves, gasoline stoves, multi-fuel stoves or spirit stoves – all outdoor and camping stoves may be carried in checked luggage. However, this only applies if they are completely emptied and cleaned of combustibles. Especially with empty fuel bottles that still smell of gasoline, the airline may refuse to transport them. Thorough cleaning before checking in your luggage is therefore a top priority to avoid trouble at the airport.
Availability of gas cartridges in the country of travel
gas cartridges for outdoor stoves are not available in all regions of the world. Sometimes there are no piercing cartridges, sometimes no screw-in cartridges, and often no gas cartridges at all. Depending on the destination, you should consider the local availability and choose a multi-fuel stove or a gasoline stove. if screw-in cartridges are available in the chosen travel destination, the uncomplicated transport of the stove by airplane (no time-consuming cleaning) clearly speaks for the variant with liquid gas.
For travelers in europe, the supply of camping gas is almost universal. However, in different regions the piercing cartridges are more popular and in other areas the screw cartridges with valve are more common. If you have the opportunity to estimate your gas needs before the trip and are traveling by car, you can save time (and usually money) by buying the necessary cartridges with a little reserve before the trip.
Disposal and recycling of gas cartridges
If empty, please dispose of properly!
Simply leaving the cartridges in nature is of course not possible! Empty gas cartridges are not waste, but raw materials that are recycled professionally. In germany, this is conveniently done via the yellow sack or the yellow garbage can, while in other countries there are some systems for taking back recyclable materials. Often the empty cartridges are also disposed of with the normal household waste and sorted out for recycling.
The old gas cartridge must be completely empty before it can be disposed of. During normal consumption of the liquid gas, a few drops usually remain in the cartridge. In the case of piercing cartridges, it is sufficient to remove the stove and wait a few seconds until the gas has evaporated. With screw-in cartridges with a valve, emptying is not quite so easy. Jetboil offers with its crunchit for example a practical recycling tool with which the cartridge is emptied completely. To let the last drop escape from the cartridge, the cartridge is "pierced" with a pointed object. The last bit of gas evaporates through the small hole. The cartridges emptied in this way are ready for recycling. However, care must be taken with cartridges that have not been completely emptied: they are still considered problem waste and may not be disposed of via the usual collection for recyclable materials. In such a case, you should ask at the town hall of your municipality when and where you can dispose of problematic materials.
