With technological advancess
and changing trends, the life span of products,
particularly in the IT and telecommunications
sectors, is on the decline. The growing consumerism
in these sectors is fuelling growth in the EEE
markets, and shorter product life spans favour
plastics because of increased consumption.
A new EU legislation (Directive 2002/96/EC)
regarding the collection and recycling of waste
from electrical and electronic equipment (WEEE)
came into effect on 13th August 2005. This means
that producers of Electrical and Electronic
Equipment (EEE) will now have to finance the
end-of-life recycling and recovery costs of
all their products. This will lead to introduction
of product design changes by original equipment
manufacturers (OEMs), which plastics processors
will have to adapt to.
Among the many repercussions of the design changes
will be possible standardization of grades and
a gradual reduction of the variety of plastics
used in EEE products. A wider range of plastics
makes the recycling process difficult and expensive
due to the separation involved prior to the
shredding of material. Polypropylene (PP) could
find greater application as they can be easily
modified to cover a wider property range, thereby
reducing the variety of plastics in appliances.
The variable recyclability of different plastics
will also become a determining factor when OEMs
choose the plastics to be used in EEE products.
Plastics that are easier to recycle will command
better value, thus Monomaterial (unfilled) plastics
or unblended and crystalline polymers will be
favoured. On the other hand, polyvinyl chloride
(PVC) and other polymers that are not easily
recyclable will progressively lose value. In
addition, coloured plastics that do not require
paint or finish coatings will become more popular,
since removal of coatings is time-consuming.
With the increased emphasis on recyclability,
some additive producers are starting to market
additives to improve the quality of recycled
plastics. While a few additives have been specifically
designed for the task, most of them such as
compatibilizers and chain extenders are familiar
chemistries that are finding new applications.
However, recyclers are hesitant to use them
as they feel that they are not economical, due
to the low price of recyclates.
Since some essential plastics in EEE are difficult
as well as expensive to recycle, it is imperative
that plastics producers support the development
of recycling technologies that simplify the
process and make it financially viable. Some
advances in this area are the development of
automatic sorting, improvement of machinery
used to process recycled plastics and extraction
of halogenated flame-retardant.
Plastics for the EEE markets are usually a small
fraction of the plastics producer's total business.
Most producers do not consider the EEE markets
as a major focus, preferring to invest in larger
sectors such as automotives or packaging. However,
this consumer-driven market calls for stable
growth and consequently, continuous demand for
plastics. As a result, plastics producers have
the opportunity to use the new legislations
to gain business by improving and demonstrating
the recyclability of their products.
