Tin
Plate and Steel Can Recycling
In
the late 1980's the steel mills began experimenting with
direct charging bundled steel cans into their scrap furnaces.
The results were positive and now regional markets for
tinplate steel cans have developed across North America. This
is good news for the recycling community. Readily removed from
the waste stream with a magnet, tin cans are included in the
container mix of most recycling programs.
The steel
industry has recently tried to promote aerosol can recycling
through their lobbying organization The Steel Recycling
Institute. Scrap processors are not overly receptive to this
program. Many of these cans arrive still under pressure or
containing flammables, which present a safety hazard when
baled or crushed. They can also create a housekeeping problem
with the release of paint or insecticide when processed. The
jury is still out on this issue.
Tin
cans can be processed in
bales
or into high density bricks
for direct shipment into a steel mill. Material can be shipped
via railcar, van trailer, dump trailer, flatbed or in walking
floor trailers. Like aluminum, each mill has preferences on
how they want material packaged and delivered. It takes a
fairly substantial baling press to make a decent tin can bale.
The product must be tight, especially if you are shipping on a
flatbed truck. We currently purchase tin cans in the east,
Midwest and southern US and Canada. Let us know what you have
available and we will contact you with a price.
Tin can bundles
are relatively low in value and are seldom imported into North
America. In 2000 a metric ton on tin can scrap was worth
between $25 and $75 per ton delivered to the greater Chicago
area. The value to recyclers depends mostly on the amount of
freight it takes to reach a steel mill. Recycling processors
were paid between $ 0 and $30 a ton for baled tin cans picked
up at their facilities in 2001.Due to an abundance of low
priced finished steel from importers, there is little demand
for scrap by the domestic North American steel mills this
year. Fortunately, this material is abundant and easy to
process so the handling costs are fairly low. Because they are
magnetic, tin cans are sorted from other recyclables
automatically with a magnetic conveyor belt. These belts
usually feed the steel directly into an automatic baling press
which produce mill quality 1000 to 2000 lb bales that are
ready for shipment.
