recent years, following increased regulatory,
public and commercial scrutiny,
and a commensurate increase in entrepreneurial
interest. Part of this evolution
has involved greater di version
of electronic waste from energy-intensive
downcycling processes (e.g., conventional
recycling), where equipment
is reverted to a raw material form. This
diversion is achieved through reuse
and refurbishing. The environm ental
and social benefits of reuse i nclude
diminished demand for new products
and virgin raw materials (with their
own environmental issues); lar ger
quantities of pure water and electricity
for associated manufacturing; less
packaging per unit; availability of technology
to wider swaths of society due
to greater affordability of pr oducts;
and diminished use of landfills.
Audiovisual components, televi -
sions, VCRs, mobile phones, o ther
handheld devices, and computer components
contain valuable eleme nts
and substances suitable for reclamation,
including lead, copper, and gold.

The Electronics TakeBack Coalition
is a campaign aimed at protect ing
human health and limiting envi ronmental
effects where electronics are
being produced, used, and discarded.
The ETBC aims to place responsibility
for disposal of technology products on
electronic manufacturers and b rand
owners, primarily through community
promotions and legal enforcement initiatives.
It provides recommendations
for consumer recycling and a l ist of
recyclers judged environmentally responsible.
Basel Action Network is uniquely
focused on addressing global environmental
injustices and economic inefficiency
of global "toxic trade". It works
for human rights and the environment
by preventing disproportionate dumping
on a large scale. It promotes sustainable
solutions and attempts to ban
waste trade.
PROCESSING
TECHNIQUE
In an alternative bulk system, a
hopper conveys material for shredding
into a sophisticated mechanical separator,
with screening and granulating
machines to separate constitue nt
metal and plastic fractions, which are
sold to smelters or plastics recyclers.
Such recycling machinery is enclosed
and employs a dust collection system.
Most of the emissions are caught by
scrubbers and screens. Magnets, eddy
currents, and trommel screens are
employed to separate glass, pl astic,
and ferrous and nonferrous met als,
which can then be further separated
at a smelter. Leaded glass from CRTs
is reused in car batteries, ammunition,
and lead wheel weights, or sol d to
foundries as a fluxing agent in processing
raw lead ore. Copper, gold, palladium,
silver, and tin are valuable metals
sold to smelters for recycling. Hazardous
smoke and gases are captured,
contained, and treated to miti gate
environmental threat. These methods
allow for safe reclamation of all valuable
computer construction materials.
Hewlett-Packard product recycl ing
solutions manager Renee St. De nis
describes its process as: "We move
them through giant shredders a bout
30 feet tall and it shreds eve rything
into pieces about the size of a quarter.
Once your disk drive is shredded
into pieces about this big, it's hard to
get the data off."

ELECTRONIC WASTE
SUBSTANCES
Some computer components can
be reused in assembling new co m-
puter products, while others a re reduced
to metals that can be re used
in applications as varied as construction,
flatware, and jewelry.
Substances found in large quantities
include epoxy resins, fiberglass,
PCBs, PVC (polyvinyl chlorides), thermosetting
plastics, lead, tin, copper,
silicon, beryllium, carbon, iron and aluminium.
Elements found in trace amounts
include americium, antimony, arsenic,
barium, bismuth, boron, cobalt , europium,
gallium, germanium, gold, indium,
lithium, manganese, nickel, niobium,
palladium, platinum, rho dium,
ruthenium, selenium, silver, tantalum,
terbium, thorium, titanium, vanadium,
and yttrium.
ADVANTAGES OF E-
WASTE MANAGEMENT
‣ Create jobs,e-cycling create jobs
for professional recyclers.
‣ Conserve natural resources, recycling
covers valuable material s
from old electronics that can be
used to make new products.
‣ Saves landfill space,e-waste i s
growing waste stream by recycling
these items.
DISADVANTAGES OF E-
WASTE MANAGEMENT:
‣ Non-biodegradable wastes take a
long time or never to decompose.
‣ The leading disadvantage of this
process is it's effective cost is very
high.
