GlaxoSmithKline
In Term 4, I attended a pharmaceutical-related sabbatical relating
to the analysis and synthesis of aspirin, where I learnt more of the
pharmaceutical industry. Even though money put into R&D has been increasing
exponentially over the years, the number of products developed every year has remained
rather constant, which shows that it has become more and more difficult to
develop such products that benefit and help to cure humans.
During the tour of the plant, we saw huge machinery that
could store 30 thousand litres of reactants, huge stirring mechanisms and huge
vessels. It was my first time visiting a chemical plant and we learnt of
various ways in which the plant is kept safe from the hazardous chemicals being
used. We learnt in school that acids corrodes metals, which is the reason why
the metal pipes were lined with glass on the inner surface. However, bases also
corrode the glass, hence those specialised pipes could only be used to carry
chemicals acidic in nature. To dry the manufactured products which came in the
form of powder, the Archimedes screw was used to allow the powder to be dried
evenly. To manually dry the product, heat was applied while pressure “sucked up”
the water.
As for the visit to their Research laboratories and Quality
labs, we saw various equipment being used such as gas chromatography machines
and scanning electron microscope machines, of which we have learned in schools
but never actually saw. These labs investigate old or new products and
processes and design ways so as to optimise the quality and quantity of the
products being produced, while the quality labs ensured the quality of the
products, to guarantee the confidence of their customers.
GSK has also designed and is constructing a “Factory of the
Future” located in Woodlands, where the solvents used and energy will be
recycled. For example, the steam generated will be converted to thermal energy
and reused over and over again. The company hopes to reduce its carbon
footprint by 30% by 2015. To see such a large MNC actively conserving the
environment, each of us should also play a part in ensuring sustainable
development in the future.
