Concept explainers
(a)
Interpretation:
Based on recycling code, identify the full form the following abbreviation: “V”.
Concept Introduction:
These day plastics are considered to be the most versatile synthetic material due to their molding property with durability. However plastic is associated with their environment harms as solid waste. They contribute a major portion to the solid waste which is nearly 8%. There are mainly six kind of mostly used plastics in world.
(b)
Interpretation:
Based on recycling code, identify the full form the following abbreviation: “PP”.
