[LOTR] What benefits could friendly relations with orcs bring to society?

Maybe the Orcs could bring medical advancements such as the medicines they use in the Uruk-Hai chapter of The Two Towers.

"Uglúk thrust a flask between his teeth and poured some burning liquid down his throat: he felt a hot fierce glow flow through him. The pain in his legs and ankles vanished. He could stand."

"Seizing him roughly Uglúk pulled him into a sitting position, and tore the bandage off his head. Then he smeared the wound with some dark stuff out of a small wooden box ... He was healing Merry in orc-fashion; and his treatment worked swiftly. When he had forced a drink from his flask down the hobbit’s throat, cut his leg-bonds, and dragged him to his feet, Merry stood up, looking pale but grim and defiant, and very much alive. The gash in his forehead gave him no more trouble, but he bore a brown scar to the end of his days."

Orcs are by nature corrupted in the process through which Morgoth created the first of their species by kidnapping newly awakened elves and twisting them. 

They will always through their twisted hröa tend towards violence and destructiveness. Mistrusting and hating other races and each other, and in the depths of their hearts, they even hate and fear their creator Morgoth as well. As such any long-term and constructive cooperation between orcs and other beings is basically impossible. 

They can and are intelligent, they are crafty engineers and their tunnelling technology is on par with that of dwarfs, although they never create things with esthetics in mind and would rather force others to do labour rather than do it themselves. As for their medical methods, elves seem to have similar and more advanced abilities and Men of the West that remained faithful can also show similar feats, healing with elvish words and simple herbs.

The only cure an orc can hope for is that once their body is dead their fëa can leave its corrupted hröa behind and be reborn in the Halls of Mandos as the elve they were meant to be.
