  1. I have noticed that some hydroponic systems use pvc piping… would it be safe to eat greens that are grown in pvc holding water and nutrients?

  7. Thankyou for the info.

  8. Yesterday, I bought a bagpack at Wal-Mart made in China and the bag contained a dark water bottle made of recycling material number two, which smelled really bad like petroleum. Do you think that those containers are safe?. For the smell I tent to desagree. I left the dark water bottle filled with water for a couple of hours after washing it. We will see if that makes it better.

  9. Styrene plastics, including styrofoam are recycled by dissolving in acetone, physically separating out the debris, then evaporating the acetone (vacuum, heat), leaving styrene again. The acetone is recycled by capturing it (pressure, cold) and recycling it to continue the process. This can be extremely economical.

  10. Hi, all. Any certificate prove LDPE is recyclable material?

    I sell plastics for a living. Many of these post consumer recycling programs are way off the mark. Many recyclers don’t know what the hell their doing. My company recycles as a plastics compounder. We however use industrial feedstreams from various molders which are much more stable and sorted properly. Of the plastics above, I’d only be concerned with PVC or chemically known as Polyvinyl Chloride. Don’t burn PVC as it liberates hydrogen chloride gas. If you were dumb enough to burn PVC with a plastic commonly used in plumbing products called Acetal, you could find yourself creating a mini toxic explosion. Also, rigid PVC generally a little safer than flexible PVC due to the decreased use of Phalate plasticizers… Oh, by the way, many in my business who purchase scrap plastics call companies like Waste Management.. “Waste of time Management”. Their stuff is just garbage and of little value unless sorted properly.

      I would love to see all of this HDPE that is being thrown into land fills, be shredded and turned into 3/8″ sheeting for low cost housing. I am also looking to see if there is a pre-made machine (of if I have to build it) to turn HDPE into hollow building studs, basically a 3/8″ walled, rectangular box of almost any length you want.
      If you are on LinkedIn, I would love to connect.

    When your saying “considered safe” does that also include being microwave safe?

  14. I”m wondering about milk cartons and other boxboard. I thought these were compostable paper or recyclable paper. I’ve just found out they are covered with Plastic # PET. So, no more into the compost. But what about recycling?
