NC State Students Launch Company To Modernize Dumpsters

Two NC State ECE students part of team that wants to create a smarter dumpster that improves the efficiency of waste collection. These students are founders of Trashr, a sensor technology that optimizes waste collection efforts to save time and money while also improving sustainability.

NC State ECE double-major students Goutham Subramanian and Hartley LeRoy (center), joined by fellow NC State Engineering students Nick Conlon and Nick Sischo all had an interest in entrepreneurship, but they had no idea their first startup would focus on waste and recycling.

These students are founders of Trashr, a sensor technology that optimizes waste collection efforts to save time and money while also improving sustainability.

“We can check how full a dumpster is with a sensor. On a huge campus like NC State, this is really helpful for dumpsters in isolated areas,” Subramanian said.

Instead of emptying faraway dumpsters on a weekly or daily schedule, Trashr will notify waste collection personnel when a dumpster is full. This results in improved efficiency, less fuel use and better waste management.

Created On Campus

The idea for Trashr emerged in 2016 during Make-a-thon, an NC State competition that challenges student teams to prototype a solution to improve campus sustainability.

“A couple hours in, we’re looking at all this data [about campus waste] and kind of flustered,” Subramanian recalled.

Overwhelmed by the amount of waste and the management process, the team narrowed its focus on improving the efficiency of waste removal. What if well-placed sensors in dumpsters could alert waste management staff when a dumpster needed to be emptied? This could eliminate inefficiencies of emptying partially-filled dumpsters.

After winning the waste category of Make-a-thon, the team reached out to NC State’s Office of Waste Reduction and Recycling. Lani St. Hill, the office’s outreach coordinator, helped the students understand the waste management industry, common operational challenges and the importance of their work.

“Innovation for waste management is crucial for our communities today as we generate globally more than 3.5 million tons of garbage per day,” St. Hill said. “Having students tackle these global challenges and find solutions can have a huge impact on the world.”

Campus As A Testbed

A few months after Make-a-thon, the team won an NC State Sustainability Fund grant to develop and test the prototype on campus. Partnering with Waste Reduction and Recycling, the students placed sensors on several campus dumpsters to learn what worked and what didn’t.

“We had this perfect idea in our head,” Subramanian said. “But we found the magnet didn’t work all the time and battery life didn’t last. So, we changed the sensor itself and every single component.”

After summer internships with different corporations, the team reunited this fall more motivated than ever to develop a market-ready product.  As they hammer out details ranging from patents and pricing to software development and analytics, the team is also further testing its sensors on campus.

“We had no idea how much went into waste management,” LeRoy said. “It’s been nice to have so much support from the entrepreneurship community and NC State in general. I’ve been surprised with how many people are willing to help.”

Now juniors, the team plans to continue refining the product, as well as a business plan.

“I’ve always been interested in entrepreneurship but never thought it’d involve trash,” Conlon said. “But now I know there are a lot of problems to be solved in this area.”
