Being the lowest fraction, it is also the highest in heavy metals such as Fe, Mg and Ni, among others.

Polyethylene terephthalate (PET) is a member of the polyester family. The presence of a large aromatic ring and repeating units give it significant strength and stability. It has numerous applications from plastic soda bottles and food containers, to carpet and furniture.
