My father long ago claimed I was like a seagull in that I would pick up anything I could get for nothing, now in my 70's nothing has changed.

Needed some bones to make bone ash for a smelting project, a logical source the local butcher shop. I now get all of their waste, once this waste has been rendered, I get gelatin, tallow, bone meal and dog food from the meat crumbs.

All of these products are easily converted into cash.

Building a larger rendering tank from landfill discards.
