I have a quantity of C41 bleach and fix concentrates left over from a time expired C41 developing kit (JOBO) and not wanting to waste it, can anyone confirm if C41 bleaches and fix concentrates are generic and can be used with any other similar C41 developer.

C41 is a standarized process, so all chemicals labelled like so must work for the film development. I personally buy the cheapest minilab chemicals I can find, so I usually mix diferent brands in my process (Fuji and Champion right now).

Still did, last I looked (that's been a year or more, though). Bleach and Fixer keep a lot better than working strength color developer...

Most of what I have is left over from a Fuji Kit which does not appear to have deteriorated at all. The bleach and fixer are seperate entities and still in sealed bottles. There is enough for 2.5l of each.

If they are rubbish, then there is the problem of disposing of them. My local authority need to issue me with a permit to take them to a recycling centre. The last time I had to get rid of bleach they threw a hissy fit about the 'bleach' they classed it as caustic household cleaner! (Civil Servants are two a penny and share braincells)

I imagine it's difficult to categorize a CN bleach as a particular waste stream. Chemically, there's little relation to a caustic cleaning agent, but in terms of a waste stream, it may end up being the best compromise. Note that the bleach contains a large amount of ammonium bromide, which is actually kind of nasty. I'd withhold judgement on the intellect of the people involved without proper understanding of the context. I bet you could have a bunch of chemistry PhD having a very heated debate on which crate to put this in at the collection center, and not reach consensus even after having done extensive theoretical work.

You have not had the sad experience of dealing with the local authority that is the body that looks after council queries where live.. It all starts out with a recorded message with the usual if you want department X, Y, or Z. Please say in a few words what you want... after the 4th or 5th attempt you eventually get put through to a human(?) who asks what you want, so you explain in as plain English as you can and they still do not grasp what you want. So you are put through to the general supervisor who is their line manager. It is (can be) marginally better, but not perfect, and you have to go through the same request again - and again - and again! If you are lucky they then comprehend what you are on about.

It is often easier to go down to the offices 10 miles away and speak face to face with the department instead of a quick 'phone call! I would suggest under qualified for the job and over paid.

That sounds like a hassle. Here you just mark the waste container clearly with the contents and leave it at the nearest hazardous waste station, which by law is available and free for household waste (as opposed to industrial and commercial). Once you've dropped it off - as long as it's clearly marked - it's the municipality's problem to find out how to dispose of it. I pour my waste chemicals in empty washer fluid containers and print custom labels for them. Never had anyone so much as bat an eye when I drop those off.

Oh if only it was that easy! You have no idea, You have to have licence to dump this that or another. You are limited to 10 'licences. year and if you use your quota you have to pay for anything else you need to get rid of, and they are not cheap!. The only thing that is free to dispose of except normal household rubbish. is old engine oil . That is probably because to sell it onto recyclers who repurpose the oil so it can be reused again.
