Envo Recycling Bins wins Rep. Cori Bush’s 2023 Congressional App Challenge in Missouri’s First District

Rep. Bush has named Sai Keertika Reddy Dorasani, a 12th Grader at Pattonville High School, as the winner of the 2023 Congressional App Challenge in Missouri’s First District.

When asked what inspired the creation of Envo Recycling Bins, the student said, “When recycling at home, I find myself often confused for a long time. if a certain item is recyclable or not. I try to read the instructions in the back, but most of the time, there are no instructions. In sports stadiums, I see a lot of just throwing all their trash and recycling in one bin, and some are confused about which bin they have to use to dispose of their trash. This is why I created Envo recycle bins, which help users see if their item is recycled or composted and dispose of those items in one of the three Envo recycle bins.”

This year’s Challenge saw an unprecedented level of participation, with 374 Members of the House of Representatives hosting competitions, surpassing the previous record of 340. A remarkable 11,334 students from across the United States competed in this year’s Challenge, marking an impressive increase of nearly 1,000 participants compared to the previous record set in 2019. The enthusiasm and creativity these students display is a testament to the growing interest in technology and signal a bright future for American innovation. The surge of ingenuity continued with a whopping 3,645 original applications flooding in, nearly a thousand more than the previous year’s high. This remarkable growth showcases the exceptional talent and innovation within our nation’s youth.


The Congressional App Challenge is an official initiative of the U.S. House of Representatives, where Members of Congress host contests in their districts for middle school and high school students, encouraging them to learn to code and inspiring them to pursue careers in computer science. This resounding show of bipartisan support emphasizes the critical importance of STEM education in today’s rapidly evolving world. Each participating Member of Congress selects a winning app from their district, and each winning team is invited to showcase their winning app to Congress during our annual #HouseOfCode festival. The program is a public-private partnership made possible through funding from Omidyar Network, AWS, Rise, theCoderSchool, Apple, and others.

The 2024 Congressional App Challenge will launch in May of 2024, and eligible students can pre-register for the competition now.
