Digestion requires enzymes and mucin for hydrolysis of ingested 
foods into smaller components, e.g. amino acids, glucose, etc. 
before it can be absorbed and utilized. There are no intestinal tract 
enzymes to hydrolyze or break down plastic, therefore no digestion of 
this material can occur. Plastic will be excreted, in the feces, without 
any change.
