For many chemicals, even the most unfriendly
for the environment, the sales system is not at all optimized to reduce the quantities that will end up in the wild.
The commercial wind
an amount of his poison, which he recommends of course too important for the application, himself recommends renewal and expiration to be sure to place a maximum. If these recommendations are not respected .... there is no longer any commitment on results, quality etc ... (Captive Client Method).
The customer is there to pay, and to cope with rejections and regulations. The manufacturer is there to wash his hands and has no interest in reducing the quantities and the toxicity of his poison.
There is another method, clearly more responsible (not necessarily much more expensive for the manufacturer).
The manufacturer no longer sells a product but a full service for his chemical. He completely manages the cycle: supply of the product, dosage of the quantities, renewal, expiration,
discharge of effluents and recycling of what can be.
As if by chance the quantities of product used decrease drastically, the dosages change, the renewal decreases significantly, the expiration dates climb up with gaillardage, products classified as non-recyclable become so as if by magic, the chemical composition changes because ... c is expensive to deal with this shit. The quality of the process is always guaranteed ....
From a certain installation size (to be defined), the second method should be made compulsory, where the manufacturer of the poison himself takes charge of effluent treatment and recycling ... The chemical impact of manufacturers on the environment would be very positively affected because this time, their profits increase with the decrease in rejections.
