[CHARLIE CRAY RESPONDS:]
STUDIES SHOW PLASTICIZERS CAN BE EMITTED OVER TIME. PLUS VINYL
CHLORIDE MONOMER, A CARCINOGEN, CAN BE RELEASED IN THE FIRST
FEW DAYS. BOTH OF THESE WOULD BE AT HIGHER LEVELS WHEN PVC IS
MICROWAVED. EVEN FDA WARNS AGAINST MICROWAVING IN PLASTIC.
WHILE MOST FLEXIBLE WRAP IS PVDC (POLYVINYLIDENE CHLORIDE) --
THAT'S SIMILAR ENOUGH TO PVC TO BE AVOIDED. EVEN THOUGH THE PRODUCTS MAY MEET
STANDARDS FOR CHEMICAL LEACHING (PPT OR WHATEVER) WHY SHOULD
WE BE EXPOSED TO ANY LEVELS (IE THE ARGUMENTS OVER RISK ARE
UNNECESSARY WHEN THERE ARE ALTERNATIVES WHICH DON'T LEACH TOXIC
CHEMICALS)? OTHER REASONS TO AVOID PVC INCLUDE ITS THE LEAST
RECYCLED PLASTIC, DIOXINS FROM PRODUCTION, AND INCINERATION.

The Summary to the Project "Development of Technology and Equipment for Solid
Organic Waste Incineration"
We have developped a new technology and equipment for solid organic waste
incineration. Woodworking industry waste (chips, shavings, wood dust), solid
organic waste of agricultural manufacture (sunflower husks, straw, maize cobs,
any vegetative biomass), waste of plastic, as a rule, are not used and cause
environmental pollution.
The burning heat of such waste is of the order of 13.4 - 16.7 MJ/kg (3200 -
4000 Kcal/kg), that is, 100 m3 of natural gas can be replaced by equivalent in
their energy potential 250 kg of organic waste.
Fire-boxes of the steam and water-heating boilers, as well as drying chambers,
heating furnace, kilns and other technological units for thermal treatment of
materials are mostly meant for burning of gaseous or liquid fu l. They are not
suitable for incineration of the organic waste, which have a substantial
content of volatiles (up to 70-80%), low density (120 - 160 kg/m2) and trigger
a sizable entrainment of fuel and ash particles.
Technology and equipment for organic waste incineration in the universal power
module with a special solid-fuel burner as the basic element is offered.
One and the same module is intended for incineration of various wastes and
their mixtures. High technological flexibility of the module allows to adjust
the heat power and the temperature mode over a wide range. This, in its turn,
provides a way for minimization of chlorine dioxide and nitrogen oxides
emissions.
The ingenious constructional approaches applied in the module and the burner
allow to feed organic waste products into the burning zone continuously,
gradually compressing them (up to the density, exceeding the bulk weight
density by the factor of 3 - 5) and to incinerate them with the use of
increased pressure air.
As this takes place, the thermal preparation of fuel is provided prior to the
burning zone, resins decompose into simple hydrocarbons and highly-intensive
burning of fuel is achieved.
Fuel feed arrangement in conjunction with the opposite movement of increased
pressure air afford intravolumetric burning with the calorific intensity of
the fire-bed surface exceeding the analogous index for layering fire-boxes by
the factor of 8 - 10 and that of for separating fire-boxes by the factor of 2
- 3. This index for the new burner may run to 50 - 80 MW/m2.
The attainment of high temperatures in the burning zone makes it possible to
provide slag-tap removal and combustion products cleaning of slag within the
combustion chamber and that ensures high environmental properties of the
suggested module. Even coal preparation waste with ash content amounting to as
much as 40 - 50% can be used as a fuel.
The simplicity and multi-purposeness, ample opportunities for regulating the
heat power and the temperature, the absence of moving parts in the zone of
high temperatures, the reduction of harmful emissions provide the advantage of
the module for solid organic waste incineration over already existing fuel
burning systems.
The suggested module can be installed in new units as well as in the units
being modernized with the aim of cutting down natural gas consumption.
Within the project framework it is suggested to built up the pilot module for
solid organic waste incineration, to conduct its all-round investigations and
to work out recommendations for its use on a mass scale in power and
technological units.

An extension of this discussion would be the recycling of microfiche.
I suspect the silver content will vary with the date of its manufacture, so
there are two possible avenues - silver recovery and film.
Does anyone know of businesses interested in this material?.
Preferably in the Texas-Louisiana-Oklahoma Area.

GREENPEACE ERECTS GIANT BUILDING BLOCKS AT NEW YORK TOY FAIR
TO PROTEST VINYL TOYS
NEW YORK CITY, February 9, 1998 -- The environmental organization
Greenpeace today erected a pyramid of oversized children's toy blocks
spelling out "NO PVC TOYS," at the opening of the annual American
International Toy Fair in New York City.
Greenpeace has been protesting internationally the continued use of
vinyl (PVC) in children's products, including toys, which have been
shown to contain significant quantities of lead, cadmium and chemical
softeners known as phthalates.
Independent studies commissioned by Greenpeace in 1997 revealed that
these materials, used to stabilize and soften vinyl products, are not
totally bound to the plastic, and can leach out when children handle
and chew on the toys.
"We should not have to fear that our children's health will be harmed
by their toys," said Lisa Finaldi, Greenpeace Toxics Campaigner.
"Greenpeace is calling on toy makers and retailers to protect our
children from the dangers of PVC by eliminating this poison plastic
from their products and store shelves."
Lead poisoning is widely recognized to be one of the most serious
threats to children's health. Even very small doses can cause
permanent damage to the nervous system and to intelligence. Cadmium
is usually considered to be five to ten times more toxic than lead.
Phthalate softeners are toxic when ingested by animals, with health
effects ranging from tumors and liver and kidney damage to
reproductive abnormalities.
In several countries, governments have urged manufacturers, retailers,
importers and licensors to stop selling soft vinyl toys for children
under age three. Austria and Denmark will ban hazardous additives in
soft PVC.
In the US, a Greenpeace report published in October 1997 revealed
alarming levels of lead and cadmium in many PVC children's products,
prompting the Consumer Product Safety Commission to request that
manufacturers eliminate lead that can reach children from household,
school, and recreation products.
Despite these serious warnings, the Toy Manufacturers of America and
the large manufacturers such as Mattel and Hasbro continue to defend
vinyl toys and children's products, as evidenced by some of the 1998
products introduced at the Toy Fair.
"What more will it take for these toy manufacturers to heed the
warnings?" said Greenpeace scientist Joe Di Gangi. "Only profit and
greed could motivate them to ignore what responsible companies already
know: its time to get PVC out of children's products."
The entire life-cycle of PVC plastic is a polluting process. Its
production involves highly toxic additives and generates hazardous
chlorinated emissions and wastes. When burned in accidental fires or
incinerators, PVC products are a significant source of dioxin and
secondary hazardous wastes.

Cindy, I think that you raise an interesting question about the use of vinyl in
products related to foods. I would add to Chicken Little's cries, "...and what
happens when we microwave our food in that stuff???"

Dear Listers,
After seeing the recent Greenpeace warnings regarding vinyl in toys, and
following some of the PVC packaging debates over the years in Europe and
the US, I've begun to wonder about the safety of flexible plastic wrap
when it comes in direct contact with food. Have any of you seen studies
on migration potential and the likely health effects? I don't want to
be a chicken little, but I also don't want to be unknowingly ingesting
toxins and serving them to my kids. It occurs to me that cling wrap
commercials just show tightly covered bowls, not cheese or fruit wrapped
in plastic.
Thank you for any leads or instruction you may be able to provide.

I feel I should chime in on the attributes of vinyl. First I must point out
most (all but one) of these advantages are applicable to durable goods
and not disposables items.
1. The chloride component is made from sea water, a renewable and
plentiful resource. this means that almost a third of the material is low
cost and plentiful.
2. It is one of the few materials that is self-extinguishing when lit by
flame. This has lead to its wide use in home construction and although it
may gas off, painted wood and other products may be just as
hazardous. One point that is often missed is the burning building is full of
items that are gassing off.
3. PCV plumbing fixtures make plumbing more affordable, both from the
affordable housing standpoint and the do it your-selfer at home. A
similar benefit is gained from CPVC pipe, which in the last 5 years, was
approved for sprinkler system use. CPVC has the potential to reduce
sprinkler costs by nearly half. According to a fire marshal I know, there
has never in a fully sprinklered building. Installing more sprinkler will
save lives.
4. The non-corrosive attributes of vinyl make the material a good choice
for containers of some types liquids. The environmental costs of a few
ounces of vinyl are often much lower than the amount of an equivalent
material, such as stainless steel. This is especially true in laboratories
and chemical containers, even for some household products.
Remember to recycle,
James
