Question

polypropylene can be recycle or not

Answer 1

A reasonable proportion of polypropylene is recycled from major industries, but a significant proportion is still dumped into landfills. It is currently not as economically viable to recycle PP as it is to recycle other polymers, in particular HDPE, LDPE and PET.

Answer 2

hello frnds.
_________

Polypropylene is a polymer plastic that is a member of 'Polyolefin' (polymer derived from alkaneus) family. It is a highly versatile material that has many beneficial physical properties, and most importantly it is also reusable.
In chemical terms, it is a linear hydrocarbon polymer, which has less dissatisfaction. On the hydrocarbon chain, a methyl group can affect the physical properties, such as melting temperature.
An easy way to identify PP is using nearby infrared radiation (NIR) techniques. It should be noted that it can not work with dark plastic because dark colors absorb radiation.
