Introduction:
Plastic, particularly single-use plastics are known to be
some of worst man-made environmental polluters.
Plastics is often seen littering beaches
and natural spots, as well as entering food chains in the form of microplastics,
losing a threats to human beings and animals.
However, the connection that the plastics have to green house
gases (GHS) emissions, the main drives of the anthropogenic climatic change, and, is perhaps
less well known and receives far less
media coverage. In 2019 report, Plastic generated 1.8 billion tonnes of
greenhouse gases emissions, 3.4% of global emission with 90% of these emissions
coming from their production and conversion from fossil fuels. By 2060, emissions
from the plastics life cycle are set to more double reaching 4.3 billion tonnes
of greenhouse gases emission.
Plastics are made from fossil fuel. They are essentially a
different form of fossil fuel, and have a very large number of carbon
footprint. Huge amounts of energy are required to create plastic plus the
energy needed to extract and transport fossil fuels comes at a great cost in
terms of emissions.
Therefore, the plastics also play a large role in
contributing to climate change. Production is projected to continue to grow at an
extremely fast rate. It is predicted that plastic production between now and
2050 will contribute over 50 gigatonnes of carbon emissions; however the real
figures will likely be much higher.
Additionally, a 2018 study found that when the most
common types of plastics are composed to sunlight and begins to degrade, they
release trace amounts of green house
gases, specially methane, a greenhouse gases 84 times more potent than carbon
dioxide.
Emissions are higher in plastics exposed to air in
comparison to those in water i.e, on land compiared to in lakes, waterways and
oceans. While these are trace amounts meaning the emissions are small, they
could have an impact in the future as plastics production and hence pollution increase
over the next thirty years.
Clearly, the carbon footprint of plastics is yet another
incentive particularly single use plastics, and an a large scale. we must continue alternatives that can be
mass-produced, and while also having a significantly lower impact in the
environment.
Solutions:
A common rebuttal to finding alternatives to plastics is
that the alternatives themselves can pose mlre of a risk to the environment,
mainly due to plastics requiring less material to make bags, bottles,
containers and other products. This is in relation to alternatives like glass
and paper, where more of the material is required to make a quality product; this
means heavier transport loads, more material used and more waste, which all
contribute to environmental degradation and emissions.
However, we have seen that these are not the only
solutions, and more and more radical alternatives to plastics are emerging
everyday. From bamboo products to algae-based packaging, the innovation that
modern technology allows us means that we have access to more solution than
simply glass or paper.
