Topic 2: Persistent waste materials (plastics) in the environment
Discuss the issue and develop an overview of the problem as described in the Topic below. Your report should address the points as indicated, estimated of
quantities, materials and other relevant information.
Please limit your report to about 4-6 pages (appendices are OK) including ****figures, tables, calculations, references.*****
Decomposition characteristics of plastics in the environment depends on both the conditions in the environment and the characteristics of the polymeric
material. Degradation rates of the plastics (even those with added starch) depends strongly on the type and amount of additives used. The half-life of most
plastics is over 100 years in landfills or the environment.
Select one type of plastic (PP: polypropylene, PS: polystyrene, PET: polyethylene terephthalate, LDPE: low density polyethylene, HDPE: high density
polyethylene PVC: polyvinyl chloride) and discuss:
-where it is used
-how much is used and discarded
-provide preliminary calculations for use and discarding rates of the specific -type of plastic

 

Sample Solution

Improper handling of plastic waste and related chemical pollution has garnered much attention in recent years owing to the associated detrimental impacts on human health and the environment. Both plastics and persistent organic pollutants, POPs, share certain common traits such as persistence, resistance to biological degradation, and the ability to get transported over long distances. Plastic waste can undergo long-range transport through rivers and the oceans, break down into microplastics and get transported through the air, or remain locked in waste dump yards and landfills. Over time, environmental processes lead to the leaching and release of accumulated POPs from these plastic wastes.

regards to the osmosis of pieces into lumps. Mill operator recognizes pieces and lumps of data, the differentiation being that a piece is comprised of various pieces of data. It is fascinating regards to the osmosis of pieces into lumps. Mill operator recognizes pieces and lumps of data, the differentiation being that a piece is comprised of various pieces of data. It is fascinating to take note of that while there is a limited ability to recall lumps of data, how much pieces in every one of those lumps can change broadly (Miller, 1956). Anyway it’s anything but a straightforward instance of having the memorable option huge pieces right away, somewhat that as each piece turns out to be more natural, it very well may be acclimatized into a lump, which is then recollected itself. Recoding is the interaction by which individual pieces are ‘recoded’ and allocated to lumps. Consequently the ends that can be drawn from Miller’s unique work is that, while there is an acknowledged breaking point to the quantity of pi
