Need address of CELBI in Portugal

[BIODATA LTDA.]

Hi!
I am a relatively new user in the internet, and I am hoping that somebody 
out there can help me.  I need to find the address, telephone number, fax, 
etc. of a Pulping anf Forestry company in Portugal.
The name of the company is Cellullose Beira Industrial S.A. CELBI.  Please 
help me, because I need a paper published by them,  which I haven't been 
able to find anywhere.

Thanks very much!!
