The article “Grading down Plastics'' brings out the necessary information about plastics which every individual should be aware of. The day to day usage of plastics has turned out to be indispensable. Right from the mobile phone to a small tag in a dress are made out of plastics. The basic requirements for a human being to survive are food, shelter and clothes, meanwhile the use of plastics is gradually becoming a need in this modern era. 



    Apart from the problem of decomposition and health hazards caused due to the use of plastics, there are certain challenges and complications involved in the process of down-cycling and in the mixing of different types of plastics together, also. Every time plastic is down-cycled, it delivers a lower grade and the chemical synthetics used will makes the whole process toxic and hazardous. The article presents four important concepts to manage plastics as: 

Identifying the resin code to sort out and process plastic accordingly 

  • Understanding the quality by measuring Grade (type) and Gauge (thickness) 
  • Avoiding added additives and coloured plastics 
  • Throwing out plastics without food and liquid scraps sticking to it 


Based on the down-cycling process, the article explains whether the common plastic items used in home passes it or not. The common Mineral water bottles, Plastic shopping bags, Take-away food containers and Ready-to-eat snacks are made out of plastic. Apart from the thicker plastic bags without any added colours or graphics, the rest of items cannot go under the down-cycling process as everything is of low gauge level. The mineral water bottle, take away food containers are all one time use products. The plastic shopping bags and plastic covers are usually very thin with an extremely low gauge, and therefore cannot be down-cycled. Whereas the Ready-to-eat snacks packets are made with metalized plastics, which is wise to avoid using even. Thus it is concluded that a proper replacement should be found for plastic in order to safe the environment.

However she introduced some simile and metaphor to draw the attention of her readers especially females .                          On getting into the title of the poem, “The Looking Glass” literally means “mirror”. But an analytical view of the title would recognize the word “glass” in itself means “mirror”, coming from its root
