     1        do what had to be done, if the technology was here, we
              would have, as we have in many cases, move our production
     2        to something different.
 
     3   Q.   What if there was not any alternative?
              A.  Continue to use pentane.
     4
         Q.   So would you say that you consider it more important for
     5        you to package your items than any destruction or damage
              this might be caused to the environment?
     6        A.  No, it is the recommended option available.
 
     7   Q.   But you said that if there were draw backs or dangers,
              then you would carry on using it unless there was
     8        something else?
              A.  I said in my opinion there were no dangers.  It is the
     9        preferred option.  I do not know the technology allows
              currently to use anything else, not that we have not been
    10        looking.  It is the safest option available causing far
              less problem to the atmosphere than the alleged CFC or
    11        HCFC.
 
    12   Q.   Have you heard about pentane blowing agents causing
              problems?  For example, contributing to the greenhouse
    13        effects and, in particular, to photo chemical smog
              formation?
    14        A.  No.
 
    15   Q.   You have not?
              A.  No.
    16
         Q.   Have you read the statement of your witness,
    17        Professor Duxbury?
              A.  Not recently, no.
    18
         MR. JUSTICE BELL:  May I just ask, do you know of any
    19        disadvantage for using pentane as a blowing agent?
              A.  Nothing other than it is a hydrocarbon.  It is the
    20        preferred option to CFC and HCFC.  We have done a lot of
              work and asked a lot of questions about trying to use
    21        carbon dioxide or nitrogen to expand polystyrene.  We have
              not been successful.
    22
              I presume the packaging people who are going to give
    23        testimony can give more details on that than I can, but
              I have not heard of any -- what was it, the word,
    24        something about tropical?
 
    25   MISS STEEL:  The greenhouse effect and photo chemical smog
              formation? 
    26        A.  I have heard with CFCs.  I have not heard it with 
              pentane.  No, sir, I have not. 
    27
         Q.   Would you like to look at Mr. Duxbury's statement?
    28        A.  Where do I look?
 
    29   Q.   It is in yellow bundle 4?
              A.  OK, 4.
