I don't have a Linkedin account. So if someone can dig a bit on this that would help. I was trying a search again on Community Waste LTD and think I might have found a shred of evidence. I came across  Osman Moro Fukuyama. His linkedin account says he is " Board Member  at Community Waste Company Ghana Ltd"

Maybe see if some of his connections line up with EWSI somewhere??
