List two uses of high density polyethylene other than those listed in the table:
HDPE plastic is also used to store bleach, baby powder, and vitamins.
Two plastics that are targeted for recycling from household waste are polyethylene terephthalate (PETE) and high density polyethylene (HDPE). One of the problems of recycling such materials is separating them. Suppose you have been hired to set up a process for separating large quantities of waste plastic that is a mixture of PETE and HDPE. Describe how you might perform this separation:
To separate PETE and HDPE plastics on an industrial scale, you could place large quantities of recycled products in a vat water so the PETE products sink while the HDPE products float.
<span>The rare earth elements include the lanthanide series, scandium and yttrium. They are a set of seventeen chemical elements in the periodic table. They really are not that rare but they occur together in nature and are hard to separate from one another.</span>
