Gas bottles and cylinders contain hazardous and toxic gases and are not recyclable in ACT recycling bins. This includes gas cylinders used to fill helium party balloons, which must NOT be placed in your recycling bins despite a recyclable symbol appearing on some bottles. Show
Disposal options
Why?LPG gas bottle, helium gas bottles, and those used to fill balloons are hazardous waste and are considered a safety hazard to workers in ACT waste facilities. Small CO2 bulbs used for inflating bike tires and whipping cream are too small for our Materials Recovery Facility to bale so collect separately for metal recycling. Old Gas canisters and bottles should never be disposed of in general waste as they can present a hazard if compacted or put into general landfill. These types of items can degrade over time releasing harmful emissions and polluting the environment for years to come, they can also over time become a serious danger to our community if left in an unsafe manner. Metrowaste Adelaide are passionate about recycling and offer a waste transfer station close to Adelaide enabling you to drop off all unwanted gas bottles and cylinders for safe and environmentally friendly disposal. We recycle all old gas bottles including standard BBQ cylinders, old vehicle LPG cylinders, old fire extinguishers, CFC and small industrial cylinders. If disposed of correctly old Gas cylinders can be effectively recycled for scrap metal and, metal fittings reused for a range of other applications. All gas bottles at the end of their useful life require decommissioning and all contents extracted to ensure safe environmentally friendly disposal. Larger type cylinders may require additional transport options and Metrowastes mini bin service may be helpful in the safe transportation of old and unwanted gas cylinders. corvus wrote:As a point of interest where did you source your refill rig from in Japan and how much did it cost please? When I costed it out at the time, the purchase made sense. I can get four 227g restaurant industry type butane canisters for $4.00 USD. Bushwalking specific canisters are $5.00 USD each for 110g canisters or $6.00 for 227g canisters. Plus of course there is the convenience of being able to top off, and the convenience of being able to custom fill when I don't need a full canister for a given route.
Interestingly, Jetboil is now selling a tool that does just that, perforate the canister so that they can be safely recycled. I suppose it must be safe. Coleman has long provided a tool for puncturing their Powermax canisters, but of course those canisters were aluminum and less likely to spark.

Thanks for the welcome. Most canisters are steel unless you happen to have some of the old Primus ones or if you have Coleman Powermax. Personally, I'm a little bit wary of puncturing them unless I'm SURE that they're empty, and even then I'd be careful. I'd attach a stove and open the valve fully (outside, away from flame) immediately before puncturing them.

I don't know if this is what you meant, but using 100% butane in liquid feed mode won't buy you much in cold weather. There needs to be some propane to pressurize the canister. 100% has to be kept at least 5C, no matter if the canister is right side up or upside down.

Filling with 100% butane to the stated weight on the canister is no big deal. If the original blend had propane or isobutane in it, 100% butane will always have less pressure. But it will be warm weather fuel only. If you want to add propane, which would be needed for cold weather, THAT is a whole another story. Screw up on propane, and you can have a very serious explosion. I have not yet been willing to take on that risk.

What's the volume of one of these canisters? How much head space do they have when full? The problem with propane (and to a lesser extent isobutane) isn't just the higher vapor pressure, but the lower density and higher thermal expansion. The canisters are designed so that the concave bottoms will invert to some extent but that only gets you so far.

As I recall from puncturing a canister and filling it with water, a 227g sized canister holds about 500ml of water. Can anyone confirm that? I hate to go on memory alone, but that sounds right. I have no idea what volume within the canister is occupied by liquid and what volume is occupied by gas. I fill to the specified weight. If I fill to the specified weight, the proportions of gas and liquid should be OK.
