Regarding the others in the business, none that I'm aware of are publicly traded so EWSI is a unique investment opportunity. Apparently they're talking with Toshiba based on some of the pics on their facebook wall.
Also, I've noticed that none of the recyclers are proficient in all aspects of the disposal, and still have a pile of stuff to dump at the end of the day. EWSI is committed to zero landfill at the end of the day, and that is where all the legislation is headed around the globe today.
IMO, Martin is ahead of the game logistically. There are a ton of recyclers that will need the help of EWSI moving forward.
I'll wager that even Apple's program could use some help from the likes of Martin Nielson, and EWSI in the future. Perhaps Al Gore will buy out EWSI down the road ;-)
