When Brayan Riascos looks at the Wisconsin cattle herds, he sees untapped potential.
A third-year Ph.D. civil and environmental engineering student from Colombia, Riascos’ research looks at what most consider the least attractive part of dairy and beef cattle — the piles of manure — and he sees what could someday be the building block of a more sustainable plastic than traditional petroleum-based production.
Any plastic made from manure undergoes several chemical makeovers before it’s a finished product, and certainly looks — and thankfully, smells — nothing like its source material.
