Científicos de la Universidad de North Carolina han desarrollado un procedimiento mediante el que, a partir del estiércol de cerdo, generan un sustituto del petróleo para la producción de asfalto de carreteras (y no, no huelen)

Manure-asphalt-1

Environment Researchers from North Carolina A&T State University have developed a process that uses pig manure as a low-cost replacement for petroleum in the production of road asphalt. In searching for bio alternatives, the group discovered that swine waste is especially rich in oils very similar to petroleum, at a grade too low to make gasoline but suited for asphalt.
