Question

What is the eventual fate of many discarded water bottles tapped answers?

Answer 1

A little percent of it (around 9.5%)  goes to recycling while a large percent goes to the landfill, ocean and beaches, where it will take years for the plastic to decompose and leak pollutants into the soil and water, threatening the health and safety of marine life.  There is a new recycling method where the plastics are shredded and mix with the other components to make hollow blocks for construction of structures.
