Reader response draft 1
In the article, “Duo turn plastic waste into
concrete idea”, Goy (2016) claims that company BlueRen found an eco-friendly
way to have the capability to incorporate plastic waste in to cement by
converting plastic waste into carbon nanotubes. With this technology, it
provides stronger attributes. Hence, more plastic waste can be recycled which
minimize the use of cement to make concrete. BlueRen's technology involves the
process of converting plastics into hydrocarbon gases and producing carbon
nanotubes. However, studies have shown the conversion of plastic waste into
carbon nanotubes often emit harmful gases and churns out high cost. BlueRen was
supported and given a funding to extend their research in this field of study.
BlueRen technology will make a feasible choice as compared to the typical
method of conversion as the benefits outweigh the disadvantages.
Firstly, we need to understanding the
importance of recycling plastic waste. According to the article "Plastic
recycling" by zero waste Singapore, it stated that plastic waste takes
more than a few hundred years to recycle and plastic waste is non-biodegradable.
This would mean that landfill space is require to bury the plastic and which
will involve natural resources and energy. Moreover, based on another article
"Plastic waste threaten to marine life", Juliette (2002) stated
plastic waste are being washed in to the ocean each year and this would mean
that animals in the ocean might consume the plastic which have the possibility
of suffocating or getting tangled up with the plastic when the animals use it
to build their nest. This might cause the animal to drown or starve, becoming
an easy prey.
Secondly, we need to understand the use of
carbon nanotubes. Carbon nanotubes are made using pure carbon. The material is
light yet strong. Based on a research article, "CNT Technology
overview", nanoscience instruments stated that carbon nanotubes are a
hundred times stronger than steel, weighs one sixth of the steel weight and is
smaller than a human hair. After carbon nanotubes was being
discovered, more popular choice to use is for structural reinforcement
with the flexibility to change to many structures and the strength. However,
the forming of carbon nanotube is inefficient as the catalyst and nanotube formation
required hot gas steam.
With carbon nanotube being a huge demand
in the market and industry, it would definitely be a key success for
BlueRen company once they are able to covert the plastic waste in to carbon
nanotubes.
Therefore, it is important to convert plastic
waste to carbon nanotubes as it would not only safe the environment, but save
cost to produce carbon nanotubes. However, the initial way of converting
plastic waste to carbon nanotubes are often too costly and emits harmful gases
after it was made possible in 2009 according to Goy(2016). Yet, BlueRen company
offers a different process concept which uses different mineral as catalyst
which is more sustainable to the environment and eco-friendly. By converting
the plastic waste to carbon nanotubes which will be used in cements, it is
estimated that there is a 30% savings in cement usuage and a cost efficient
alternative to recycle the plastic waste rather than disposing it through
burning or landfill. This brings out the best of both world as the idea would
not only be cost saving, but also environmentally friendly.
In retrospect, converting plastic waste to
carbon nanotube offers a different kind of solution towards recycling plastic
waste and a cost saving solution to carbon nanotubes which is a favourable
solution.
