New liquid soap packaged is in old plastic soda bottles, plastic water bottles and glass bottles.
Duh. From the New Soap, Old Bottle web site: "We sell brand new liquid soap packaged in old plastic soda bottles, plastic water bottles and glass beer bottles to help clean up our environment. Each bottle is cleaned, sanitized and processed for reuse as packaging for your favorite brand of liquid soap. Big companies aren't going to do this on their own. So, we'll do it for them. We buy name brand liquid soap by the barrel and package it in old bottles here in America." The cherry on top is that in addition to selling name-brand cleaners like Windex and SoftSoap, the site allows you to order environmentally friendly alternatives. You can also set up a recurring order so you (or your business, or school) never run out. Hopefully they'll start stocking this at Target or Wal-Mart sometime soon.
