It was a fitting moniker for a man who made millions in the waste-management business, cleaning up his native New Orleans during the post-Katrina years.
The "trash king," Sidney Torres IV, fully embraced social entrepreneurship last year, when he launched a business to help the city clean up its streets of violent crime. It's something he thinks more business leaders should do.
"There was a storm brewing, and it wasn't a hurricane," Torres told CNBC, reflecting on the crime wave he witnessed in New Orleans' French Quarter in 2014, when violent crime jumped 40 percent.
