why bioplastic is just marketing gimmick?

What is come in our mind when we hear about bioplastic?

Yes,that it is bio friendly.

But that not a true

Bio plastic is not means bio friendly. "Bio plastic just means it made from bio based product" or "bio degradable in nature at controlled atmosphere"

Bio based plastic:

Bioplastic-or biopolymers-is distinct from conventional plastic because it is made from renewable plant feedstocks such as corn, cassava, sugar beet, or sugarcane and notpetrochemicals.

Bioplastic includes polylactic acid (PLA),plant-derived polyethylene terephthalate (PET), polyhydroxyal-kanoate (PHA), and can be mixtures of biopolymers, petro-chemical-derived plastic, and fibers.

Bioplastic is not inherently biodegradable. while manufacturing this plastic gasoline based ethalene or propylene replaced with bio based products made from generally fermentation process.for example polylactive acid.this plastic have characteristics nearly same as general synthetic plastic.they not biodegrade in nature.but their manufacturing process have less carbon footprint than synthetic crude oil based plastic.

The material used in plant-based PET is indistinguishable from its petrochemical equivalent. Plant-based PET, like petrochemical PET, will not decompose, but it can be recycled with conventional PET.Plant-derived PET thus has the same environmental impact asconventional plastic. PLA is not suitable for home composting biodegradation requires an industrial composting process that uses high temperatures (>58 ° C) and 50 percent relative humidity (most home composters operate at <60 ° C and only rarely reach temperatures greater than this).Pure bioplastic will release carbon dioxide (or methane) and water when it breaks down. However, if additives or toxins havebeen added during the manufacturing process, as is generally the case, these may be released during degradation. As with fossil fuel-based plastic, chemicals may be added to a bioplas-tic to add strength, prevent wrinkling, or confer breathability.Further research and lifecycle analyses will help to understandthe role and impacts of different bioplastics.

Environmental Impacts of
Bioplastics 

Bioplastics have been found to be

superior of petroplastics in efficiency to terms petroleum energy consumption, and carbon emissions,but inferior to petroplastics in cost and

applicability. Bioplastic production and use are regarded as more sustainable than

petroplastics because of less requirement of foss fuel as carbon source, less greenhouse gas emission and reduction in

hazardous waste generation. One metric ton of bioplastics generates between 0.8 and 3.2 fewer metric tons of carbon

dioxide than one metric ton of petroleum-based plastics.

But bioplastic manufacture is dependent on petroleum. manufacturer Novamonthas

has reported that production of one kilogram of bioplastic product requires 500g of petroleum and almost 80% of

the energy required to produce common plastic.

NatureWorks has reported that PLA (polylactic acid) bioplastic production delivers a fossil fuel saving of between 25 and 68 per cent compared with petroleum Italian on polyethylene. A detailed study conducted by Franklin Associates and Athena Institute reported that bioplastics are

less environmentally damaging for some products, but damaging for others. This study does not consider the end-of-life of the products, thus ignores environmentally more

the possible methane emissions. 

So conclusion is bioplastic is as harmful  to nature as synthetic plastic.corporates just manipulating customers mind to fool them.
