Biodegradable Plastics are superior to any other plastic.

Hello bakhter, 10.0 Decomposition of the plastic 10.1 It is true that majority of the decomposition products would be carbon dioxide; oxygen and water, bio-plastic also contain metals such as lead and cobalt to accelerate the decay process. These metals are known carcinogen (Kazantzis, G. 1981). 11.0 Economically viable to continue at least until it has become unsustainable 11.1 To argue that if a product has a due date is inferior is deeply flawed. First, our argument consists of at-this-moment comparison of traditional plastics and bio-plastics. This means currently, bio-plastics is still inferior to traditional in terms of cost. 12.0 "corn is such a expendable product…" 12.1 corns may be expendable however for farmers who want to make the most money he or she needs to do one or two things. First, farmers might want to consider clearing his field to grow corns instead of rice. This means lesser rice yield and thus higher prices for rice. 12.2 Second, farmers might want to clear forested land to grow additional cons. This thus would lead to unintended environmental effects which ultimately, government need to pump money to address. This in turn affects the consumers as we are the one who would be paying taxes. 13.0 Recycling 13.1 So far I have not given any argument about recycling except the points to help me remember. The small percentage of recycling does not nullify my claim since we are able to get back some of the cost of producing plastic as compared to bio-plastics which currently does not have any recycling programs. 13.2 This brings my next point as to why bio-plastics do not lend themselves to being recyclable. PLA have a high energy cost to produce and a relatively high energy cost to recycle. This means, it is more feasible to just produce the plastic from stock. 13.3 In contrast, traditional plastics takes low energy to produce and have a low energy cost (75% less) to recycle. (Hutchinson, 2008) 14.0 Uses 14.1 It may be true that increasingly, bio-plastics are lending themselves to a wider spectrum of uses. However, traditional plastics are still superior in quality and the variant of uses. 14.2 Plastic Surgery, 14.2a silicon is the go-to plastic for implants because it does not degenerate inside the human body. Indeed traditional plastics are selected for such uses as it has minimum environmental interaction unlike bio-plastics which are made with the opposite intention in mind 14.3 Storage and disposal of bio-chemical waste 14.3a again traditional plastics have the upper hand as we do not want contaminant to leach out 14.4 Fireproof material 14.4a Aerogel and other high heat plastics are ideal for use in shutter re-entry and other high heat environment. 14.5 Long lasting products 14.5a consumer items which are built to last such also do not use bio-plastics 14.6 I could go on about this but I think that enough examples for the day.
