Computers may contain components that are hazardous wastes. In CRTs,
the main culprit is not phosphorus, but lead. The frit, the material
that unites the front panel with the back panel of a CRT, is almost
pure lead and may be hazardous waste by virtue of failing the TCLP
test for lead of 5 mg/liter (ppm). Likewise, the circuits boards may
be hazardous wastes, for example, due to high levels of lead. Even if
the boards are hazardous wastes, they can be managed as scrap metal
and, as such, are not subject to federal (and Ohio) hazardous waste
requirements. Ohio does not consider CRTs hazardous wastes if they
are reclaimed to recover useful materials.

Briefly, I want to share some info with you on the issue from another
listserver.

The typical computer monitor and television tube, aka Cathode Ray Tube
(CRT), is not homogenous. A CRT is composed of a front panel, back
panel (funnel), and neck (or gun). The front and back panels are
joined by a special frit. The front panel is basically soda-lime
glass contains about 3% lead. The back panel may contain up to 22%
lead. The frit is usually very high in lead and may fail the TCLP
test, thus exhibit the hazardous waste characteristic of toxicity for
lead. CRTs also may contain small amounts of barium, strontium, and
other chemicals for the proper color or physical characteristics.
Lead is added to the glass to enhance the forming process and as a
shield to the radiation generated within the tube. The gun mechanism
is usually the primary site of malfunction. It can be removed from a
defective tube, repaired, and replaced (for example by the Zenith
Corp.)

CRT manufacturers/assemblers/recyclers typically process spent CRT
glass
that satisfies their acceptance specifications. Funnel glass is
generally
fairly uniform in composition from manufacturer to manufacturer, but
panel glass is more problematic. TV monitor panel glass may have 4 or
5 basic compositions. This complicates the process of getting CRTs
recycled. As a general rule, undesirable glass is sent to a
fiberglass manufacturer. Some glass processors can blend
undesirable/off-spec glass to the desired specification.

The dealers listed below handle computer and electronic scrap and can
recycle, process, or broker CRTs. Please note the list of computer
and electronic scrap dealers.
