In Texas, if the deer are received by the processor's cold storage facility with proper tags, and the information entered into a log book, then he can do what he wishes with the "inedible" parts:  sell, trash, give away, or donate them.  As long as the facility is legal and is considered a "final destination", all inedible parts coming out of the facility are legal to posses in any amount without documentation.
Sale of Inedible Wildlife Parts: The following inedible wildlife parts may be purchased or sold provided the part was lawfully taken or possessed:
    Hair, hide, antlers, bones, horns, skull, hooves, or sinew from the following game animals: mule deer, white-tailed deer, pronghorn antelope, desert bighorn sheep, gray or cat squirrels, fox squirrels or red squirrels, and collared peccary or javelina. 
Possession Limit: For all wildlife resources taken for personal consumption and for which there is a possession limit, the possession limit shall not apply after the wildlife resource has reached the possessor's permanent residence and is finally processed.

  Check to make sure.  You should be able to posses parts that have been processed.
