In the
article “Duo turn plastic waste into concrete idea”, Goy (2016) claims that
company BlueRen found an eco-friendly way to incorporate plastic waste into
cement by converting plastic waste into carbon nanotubes. Goy stated the
technology provides stronger attributes which enhances the overall strength of
concrete. Hence, more plastic waste can be recycled which minimizes the use of
cement to make concrete. Goy mentioned BlueRen's technology involves the
process of converting plastics into hydrocarbon gases and producing carbon
nanotubes. Despite studies have shown the normal conversion of plastic waste
into carbon nanotubes often emit harmful gases and result in higher costs, BlueRen
uses a different catalyst which is more environmentally friendly. BlueRen was
supported by external sources and given a funding to extend their research in
this field of study. Recycled carbon nanotubes from plastic waste has the
capability of protecting the environment while being cost-effective leads to a
huge market demand in the near future.
First,
understanding the importance of recycling plastic waste and environmental
protection is essential. According to Zero Waste Singapore, they stated that plastic
waste takes more than a few hundred years to recycle and plastic waste is non-biodegradable.
Landfill spaces are required to bury the plastic or by burning the plastic
waste which involves natural resources and energy. Moreover, another article by
Jowit (2002) stated that plastic wastes were being washed in to the ocean each
year and animals in the ocean might consume the plastic. This raises the
possibility of suffocating or getting tangled up with the plastic when the
animals use the plastic waste to build their nest which causes the animals to
drown or starve. Thus, the importance of recycling plastic waste will
undeniably save the environment and protect animals from the potential harm of
plastic waste.
Next, the
need to understand the demand of carbon nanotubes in the market and how the
conversion is cost saving is necessary. Carbon nanotubes are made using
pure carbon which is light yet strong. Based on "CNT Technology
Overview", nanoscience instruments stated that carbon nanotubes are a
hundred times stronger than steel, weighs one-sixth of steel’s weight and is
thinner than a strand of human hair. Carbon nanotubes is widely used for
structural reinforcement with the flexibility to change many structures and
their strength after being discovered. However, forming of the carbon nanotubes
is inefficient as the catalyst and nanotube formation requires hot gas steam
making it too costly and detrimental due to the harmful gases produced.
Therefore, BlueRen company offers a different process concept which uses
different minerals as a catalyst, making it more sustainable to the environment
and eco-friendly. With carbon nanotube being a huge demand in the
market and industry, it would be a key success for BlueRen company once they
are able to covert the plastic waste into carbon nanotubes with the new process
concept.
Converting
plastic waste to carbon nanotubes saves the environment and costs to produce
carbon nanotubes by using BlueRen technology. Converting plastic waste to
carbon nanotubes implementing in cement is estimated to have a 30% reduction in
cement usage, acting as a cost-efficient alternative. Furthermore, recycling
plastic waste will be a better alternative as compared to burning or landfill.
In
hindsight, converting plastic waste to carbon nanotube is a favourable solution
for the necessity to protect the environment while being able to be a cost
saving solution.
