Yes I feel sad to throw away used chemicals when I know they have much life still left in them.
Would you have me throw away all of the food left after a meal? When I know that I can easily save the extra food and eat again the next day.
Or if I buy new clothes and they become dirty, would you have me throw them away and buy more? When I could very easily wash them to a like-new appearance and wear them again. Is that not wasteful?
So why must I throw away my chemicals when I know that I can easily repair them and use them again?
Momad, I must confess that I'm speaking to you in humor, to pretend as if you are wasteful, which I know that you are not.
On a serious note, my experience is from a photofinishing lab where we used over 5,000 gallons of replenishers every day. That is about 20,000 liters per day. So we have the opportunity to reuse some of this, why not? Everything we can reuse is something that doesn't have to be disposed of, and something that doesn't have to be bought new. And so the money saved can go to pay employees (but more than likely to company profit).
Now this sort of saving is not for everyone, because it takes extra labor and equipment to do it. So you don't want to spend five dollars of work to save one dollar of chemicals. But if your five dollar of work can save, say, five HUNDRED dollars of chemicals, then shouldn't you do it? (Of course you should.)
As a very rough estimate, comparing a typical user of mix-it, use-it, and throw-it-away photo chemicals versus a commercial lab using best practices of replenishment, use of squeegees after every tank, and regenerating bleach and fix, I would say that the commercial lab can have a chemical cost, per roll, about ten times lower. Note that I did not specifically calculate this, just a rough guess from past experience.
Yes, yes, dear brother ,, I know that you speak with humor.
- But the difference is great, dear brother. The difference is large between the quantities produced by a professional laboratory and between the quantities produced by a home user.
Basically, there is no comparison.
So I see our friend OP has consumed his valuable time reading, researching, reviewing, checking, and ultimately the value of those chemical raw materials is worth nothing.
- I am a really poor man, and it suffices to tell you that I am Egyptian, and this implies that I am poor and not ashamed of that.
But sometimes time is more precious than the cost of these materials, and sometimes the presence of this chemistry in the home becomes a burden and takes place.
So I am speaking out of public interest ,,
I am not a rich man and sometimes I mix two chemicals in order to give the same effect as another little expensive substance ,, and all of this in order to save money ,,,
But in that case ,, I try to renew the chemistry only once and if I have doubts about its effectiveness, I immediately get rid of it without regret. And in this case as someone who gets rid of his food waste after digesting it and it is not suitable for eating
God bless you brother
