It's the final day of the Waste Management Open going on in Scottsdale.
The WM Open is one of the largest zero waste events and most sustainable sporting events in the world.
"It takes months of planning and a lot going into the tournament," said Janette Micelli, the Communication Manager of Waste Management.
You may notice there are no trash cans at the WMO. And that's because nothing will end up in a landfill.
"Here at our zero waste event, absolutely nothing will go to the landfill and it goes on to its next best use," Micelli said.
The next best use if first gathered in recycling and compost bins.
"Recycling, compost, donation, reuse or the creation of energy," Micelli said.
She says tons of material are picked up, organized and sent off to be further separated.
"Months in advance we're working with Thunderbirds and all vendors and sponsors to make sure they bring in all the appropriate materials. Everything has to be recyclable, compostable or reusable," Micelli said.
They hope to inspire other events to do the same. In 2017, Micelli says 336 tons of material was recycled and 229 tons of material composted.
"if you think about it, over 655,000 fans come through here over a seven day period. That obviously is the highest attended event on the PGA tour, and we hope we're inspiring other events to be green just like we are," Micelli said.
Waste Management has been the title sponsor since 2010. They say for five straight years, nothing has gone to the landfill.
