Great article! You're right on the mark regarding the recyclability of plastic bags. Like you, I conducted the same post-mortem on where they went after being stuffed in a retailers curbside collection bin. I too found that all roads lead back to Trex and contacted them to learn more about their program. Their recycling efforts and sustainability programs are beyond commendable, they are a model for anyone producing durable products using plastic. They estimate that 32,000 US retailers are now participating in their recycling program. And, all of their competitors have moved over to the same production approach. Nice job!
