I called the manufacturer today and spoke to a rep. This container is not made of virgin polypropylene. It is from recycled polypropylene. This does mean it is not food safe. It is for storage use only and completely safe for that purpose. The reycle code does not indicate which source of the material was used. Generally white or bronze plastics are more likely to be virgin sourced since recycled resins are darker in color. Evenso, unless it says its food safe you can't be sure. Call the manufacturer. Just as an example of what I mean; When reusable recycled shopping bags from major retailers was tested recently, many were found to have lead content above what is considered safe for food. Yet many people have promoted using them as growbags on the internet.

I've used this particular one for at least 5 years now, bringing it indoors to keep the Bay Laurel alive over the winter.
