Conventional Plastics depend largely on food packaging and circuit boards. Their versatility, cost, low weight, and durability is related to it, hence is also their dependence on modern living.
These advantages also have significant drawbacks in waste disposal as well as in replacement materials. Since chemical structure of plastic consists of strong C-C bond links along with polyethylene, polypropylene and polystyrene, it take about thousands of years to completely degrade.
In case it is not disposed of properly, plastic continues to persist in the environment, thus leading to plastic pollution. Therefore, most of the plastic in the present times is mostly single-use. Improper disposal of plastic which leads to toxicity of sea, bio-accumulation of plastic chemicals, micro-plastic particles is not the only grave problem.
Conventional Plastic which is derived from petroleum generate high carbon footprint, thus adding to global warming. Over the years, scientists have created viable alternatives for conventional plastics. However, it is a challenge to create alternatives which have comparable material properties that can be both produced and disposed in a sustainable way.
One of such options is bio plastic which is derived form a renewable biomass source, for instance, starch, vegetable oils and food waste. Although bio plastics do not biodegrade faster in comparison to petrochemical analogues, by-products of bio plastic are environment friendly and non-toxic. They however remain in the environment for a considerable period of time and can be equally harmful if not disposed properly.
