At a farm outside Las Vegas, a herd of pigs feasts on lobster, sausage links and beef. In town, people at a community center sit for a dinner that may include sliders and truffle mac and cheese.
The two meals have something in common：Both came from the kitchens of Sin City’s opulent casinos, where the axiom of excess is increasingly being reconsidered and waste reduction has taken hold.
The environmental and financial impacts of leftover food are more important than ever to Las Vegas’ world-famous casinos, which in recent years have developed and expanded innovative practices to cut back on what they send to the landfill by thousands of tons a year.
Food scraps are turned into compost or taken to a farm to feed thousands of pigs. Expired minibar snacks are donated to community organizations. Banquet meals that were never served go to a food bank. Oyster shells are even shipped thousands of miles to Chesapeake Bay.
