Managing a multiple crew construction site for scrapping.

I've transitioned from from road building to site work jobs. This entails demo, sitework,and underground. In this transition I've got into the scrapping behavior from the disgust of large volume of waste that could laden my wallet and not fill dumpsters. Whats a good tip for lessening the splits I've had to encounter since its "become" lucrative.

I am working a demo job right now. Scrap is clearly stated as the property of the company doing the job.

I would try and get it in righting from the owner/financer
