Why can plastic “nurdles” be made into other plastic forms but formed plastic can no longer be as easily recycled?

Question

To my knowledge, nurdles are the primary pellets that are used as the source to form all plastic pieces. If they get melted down and formed into other plastic parts, what changes that makes those formed parts so much more difficult to melt down into another form?

Answer 1

Think about it like this : murders are the raw eggs. Shaping them into day a water bottle changes the chemical structure of the polymers just like a cooked egg is now fundamentally different than a raw egg… the raw egg can go into cookies or cakes or pudding etc etc but the cooked egg can no longer be used for much else…
