Disposable bottles, I have picked one up from NRS Ipswich and i am thinking what a waste. First of all, OK there is enough in there to gas up two a/c's but then going by the book you then have to reclaim the remainder into a reclaim bottle (Usually mixed) before disposing of it, then eventually when your'e reclaim is full it goes off to be distroyed. Is this a total waste of resorces or what.
