It is also interesting to note that the EPA was pushing for lead battery recycling but have stopped pushing so hard once it got to 85%. Why? Because of the results of a study. Most primary lead refining in the continental US is done in Missouri and (I think) Montana. Not two of the most populated states in the union, certainly not in the areas where the refining is done. However, most secondary lead smelting (read recycling ) is in California, populated parts of Texas and the Atlantic east coast. The report concludes there is more potential for short term harm from increasing the secondary recycling than from the batteries not being recycled. The report does not say what would happen if there was less battery recycling. Don't take my word for it, get the book "Economics of Waste" by Richard C. Porter, a real eye opener.

No,
They want to prevent the use of Lead Free solder and
all the costs of changing a 50 year old process for no
scientific reason, force recycling, and prevent the
change for the sole reason to capture market share.
