Problem Statement:
Globally, over 1 million plastic bottles are purchased every minute, which translates to over 1 billion bottles per day. The global recycling rate for plastic bottles is estimated to be less than 25%, with some reports suggesting it’s as low as 5% for single-use plastic bottles.
These statistics highlight the urgent need for sustainable solutions to address the environmental, resource, and health challenges posed by the widespread use of plastic water bottles.

About the Innovation:
This team of young inventors designed a plastic bottle with a special cap that contains the fungus Pestalopia Microspore. Pestalotiopsis microspora is a species of endophytic fungus capable of breaking down and digesting polyurethane. Once the bottle is used, a twist in the cap releases the fungi which digest the plastic bottle in approximately 2 weeks!

DiscoverSTEM founders Mirza Rizwan and Mirza Faizan have made history by becoming the first Indian to win the coveted George Washington Honor Medal from the Freedoms Foundation – USA.

Started in 1949 by former US President Dwight D. Eisenhower, Freedoms Foundation honors exceptional contributions of Americans towards communities in the USA. Generally reserved for the US citizens, the awarding organization made an exception to recognize the stellar research work and its impact of India’s Mr. Rizwan in designing and implementing a unique STEM & Innovation program for American children, thereby revolutionizing the education system in the USA.

Few of the other notable non-US citizens who have received George Washington Honor Medal include Ms. Margaret Thatcher (Former Prime Minister of United Kingdom), Lech Walesa (Former President of Poland and Noble Prize winner) and world-renowned Russian writer Aleksandr Solzhenitsyn. As the latest recipients of this prestigious honor, Mirza brothers join historically acclaimed group of citizens whose work and dedication advance the American ideals, the award letter says.

Some of the distinguished US citizens who have received this award for their stellar contributions in their field are Walt Disney, Astronauts Sally Ride and John Glenn, Capt. Sully Sullenberger, Athletes like Arthur Ashe, George Foreman and Tiger Woods and famous US educator Jaime Escalante.
