Answer:
It is necessary to adopt/focus on 5R principles (Reduce, Reprocess, Reuse, Recycle and Recover) of waste management for sustainable development. Port generates four types of wastes i.e., municipal solid waste, industrial waste, bio-medical waste and e-waste.
Explanation:
The primary difference between the two is that Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming, while thermoplastics can be reheated, remolded, and cooled as necessary without causing any chemical changes.
