    Clearly a good step to radically improve energy efficiency in the production of polycarbonates.

    With the global recession, many chemical plants will have a hard time justifying a move from the present phosgene chemistry. However, long-term (Five to seven years) the energy savings alone will make such an upgrade very attractive

    Just after reading this, I read about arboform; a composite polymer based on lignin (byproduct of paper production). All very interesting.

    I thought you would like that. Nothing wrong with turning a waste product into a useful product.

    Chemical Processing is a good journal to subscribe to

    So what are we going to do with the leftover phosgene? Start another war with the Germans?

    Hmmmm, never thought about that.

    What *are* we going to do with all that phosgene??

    I'll think of something ....
