     1        polystyrene to make the foam.
 
     2   Q.   I see.  Point 4: "Confirm that we started supply of foam
              boxes in China in January 93"?
     3        A.  OK.
 
     4   Q.   What is the point of that?  That means they were using
              HCFCs to China in January 1993?
     5        A.  Correct.  They were a supplier to that market.
 
     6   Q.   Those foam boxes, were they, I might have got this wrong,
              were they supplied by a company in America?
     7        A.  No.  Pacific Cup -----
 
     8   Q.   Or was it replaced by a company in America?
              A.  Pacific Cup appears to have an address in Hong Kong.
     9
         Q.   Yes, I understand that.  But I thought you said they
    10        brought those materials?
              A.  I said they licensed technology to produce.  Dow in
    11        America developed a technology that enabled an industrial
              process to use C02 as a blowing agent for polystyrene foam
    12        and subsequently sold, not sold that licence, but licensed
              that technology to Pacific Cup for a fee.
    13
         Q.   Did you in America, did McDonald's ever have paper
    14        packaging before they had polystyrene packaging for the
              same purpose?
    15        A.  I think prior to 1985 there was paper and paper board
              packaging used rather than foam clam shells.
    16
         Q.   So when you changed to HCFCs in 1988ish, you could have
    17        changed to paper packaging?
              A.  Well, in 1975 when some transition was made from paper
    18        board to foam, there were studies done that found that the
              use of the foam package had a less environmental impact
    19        than did use of paper board packaging in our country.  So
              we knew that if that was the case then, the industry
    20        conducted a study in 1990 showing that the environmental
              impact of using those paper board containers was either
    21        balanced with or worst than using the foam containers in
              our country with the given regional issues in the
    22        environment we had. So we did not feel that was a good
              alternative.
    23
         Q.   It was an alternative but not as good as HCFC-22?
    24        A.  It was not as good an alternative, no.
 
    25   Q.   Even though HCFC-22, HCFCs were known to damage the ozone
              layer but only at small rate, you still chose to carry on 
    26        using those when you could have chosen paper? 
              A.  We chose the alternative with the least environmental 
    27        impact as we knew it.
 
    28   Q.   OK.  For pentane and butane you said emissions of
              hydrocarbons has a problem in the atmosphere.  What
    29        exactly are the problems caused by the emissions of
              pentane and butane?
    30        A.  I think that was already established.  They are,
              hydrocarbons cause smog and they contribute to enhanced
