This year, more than 13 million plastic caps were collected by local Huntsville area schools.
Boeing, The Solid Waste Disposal Authority and Operation Green Team recognized each school and awarded cash prizes on Wednesday.
The project lasts throughout the school year and in total, the schools receive a total of $28,000 to use how they best see fit.
The grand prize winner took $2,000 for collecting more than 1 million plastic caps.
"It was really fun, we counted a lot of tops. We counted them every day, we had to take some home and count them," said Miracle Burwell, a local student who collected plastic caps.
Organizers say they hope to continue growing the program each year.
