Our Unique Bi-Directional Dense Medium Barrel
The centerpiece of ESR
technology is a unique bi-directional dense medium barrel
that is, undoubtedly, the most accurate dense medium
separator on the market today. In this revolutionary
sorting process, the suspension fines needed to change the
density of water for all separations below a density of 1.6
are obtained nowhere else but from the ultra-fine inorganic
metals and glass generated in abundance by hammer-mill
shredding. Normally these fines simply report to landfill,
but now they compete head-on with some of the finest
suspension-creating materials on the market today.
Paradoxically this shredder dust of absolutely no value
whatsoever totally transformed the economics of recycling
waste.
Extracting Metals from Waste
What happens when we take
the logic of a large mineral separation facility and apply
it to the recycling of automobile, industrial, electronic
and municipal waste? Over 20 years ago, ESR International
posed this question and got some fairly amazing answers.
What was once considered waste, what once demanded a great
deal of money to landfill, suddenly transforms itself into
multiple streams of metals and plastics worth at times
thousands of dollars per ton. When someone is able to
extract, from materials destined for landfill, over 40 tons
per hour of non-ferrous metals at an average value of over
$1,000 per ton, then we begin to realize that in
landfilling waste we are often throwing away some of the
most valuable resources our planet has to offer.
