However, as stewards of this wonderful creation
we occasionally use extremely poor judgment and
are sometimes just trashy. It is from this view
point that Du-More Inc. Dental products are made
of a plastic that biodegrades to nothing more
that CO2, water and humus without leaving
fragments of petro-polymers in the soil.
How is this possible?
We all know that plastic is used in numerous applications that are
beneficial to mankind. Plastics are currently
made from naphtha, which is a by-product of oil
refining, and oil is of course a finite
resource. However, this by-product arises
because the world need fuels and oils for
engines, and would arise whether or not the
by-product were used to make plastic goods, It
is possible to make oxo-biodegradable plastic
from ethanol, which is in turn made from sugar
or other carbohydrates, and this is being done
in Brazil. Unless the oil resources are
left under the ground carbon dioxide will
inevitable is released, but until other fuels
and lubricants have been developed for engines,
it makes good environmental sense to use the
by-product, instead of wasting it by "flare-off"
at the refinery and emitting carbon dioxide to
atmosphere at that stage.
Oxo-Biodegradable 2 Plastic
1. This new technology
produces plastic which degrades by a process
of OXO-degradation.
2. The technology is based on a very small
amount of pro-degradant additive being
introduced into the conventional
manufacturing process, thereby changing the
behavior of the plastic.
3. The degradation of the plastic begins
when the programmed service life is over (as
controlled by the additive composition) and
the product is no longer required.
4. The plastic will be consumed by bacteria
and fungi after the additive has reduced the
molecular structure to a level 3 which
permits living micro-organisms access to the
carbon and hydrogen. It can therefore be
properly described as "biodegradable." The
process continues until the material has
biodegraded to nothing more than CO2, water,
and humus. It does not leave fragment of
petro polymers in the soil.
5. The length of time it takes for
oxo-biodegradable plastic products to
degrade can be 'programmed' at the time of
manufacture and can be as little as a few
months or as much as a few years.
6. Unlike PVC, the polymers from which oxo-biodegradable polymers emit
neither methane nor nitrous oxide under
aerobic or anaerobic conditions.
Socially Responsible Consumers
at present have only branded or Store branded
dental items to select. Dr. Du-More's
Toothbrushes, Dental Flossers, and Toothpicks
offer an excellent choice of quality 100% Green
Products made in the USA .
The argument that
oxo-biodegradable plastics are undesirable
because their components are designed to be
deliberately and totally lost is a fallacy,
because the advantages of oxo-biodegradable
products are not mutually exclusive. If people
want to incinerate with heat recovery, or
mechanically recycle them or compost the or
re-use them, then that's OK, and they cost very
little if anything more than conventional
products. The key point is what happen to the
plastic which is not collected, and get into the
environment as LITTER.
Oxo-biodegradable plastic is not "deliberately
and totally lost" because biodegradation on land
is a source of plant nutrients, just as is
straw, grass, leaves etc.
