Question

What number on the bottom of a water bottle is reusable?

Answer 1

Ummmmmm.....this question needs a little rethinking and restating.  As it is written, it askes which 'number' is reusable.  It also doesn't say what kind of water bottle it is.  Is it like a water cooler kind of bottle (which are always recycled and reused), or one of those disposable sports bottles (which are made from PET and generally recycled less their caps)?

The numbers on the bottoms of most bottles are a combination of the mold number and the manufacturing date.

Answer 2

its 1 and 2,  most plastic bottles are either1 or 2, other numbers are also recyclable but not as common

Answer 3

i believe you are referring to the number in the triangle right? if i remember correctly, to be able to reuse it safely, the number should be at least 5.
