That was the start of many other inventions - one of which is now being showcased at Expo 2020 Visitor Centre in Dubai, reports The Khaleej Times. Nine-year-old Harshith is a Grade 4 student of Bright Riders School Abu Dhabi. His project, called 'Robotic waste segregation to organic composting', was chosen to be part of Expo 2020 Young Innovators programme. "My robot, Wsegrebot, segregates waste into green, wet, metal, paper, wood and plastic.

The wet and brown waste, like paper and wood, will be shredded. Then the waste is converted into organic compost, which turns into soil when mixed with sand," Harshith said. By turning waste into something that would be useful for farming, he seeks to "turn the desert into a garden". "My vision for the project is to make the UAE green, and promote chemicalfree agriculture. For this, I make my projects from waste materials," the little eco-warrior said wearing the Expo 2020 badge given to him by officials.

He has also made a cleaning robot using old cars, cardboard and motor. "I had made a smaller robot to help my mother. Now I have made a bigger one to help with cleaning." For the past few years, Harshith is also leading a campaign against plastic use. He makes paper bags to replace plastic bags in baqalas and other shops. He will continue and expand his drive when he returns to his native city of Srikakulam in the Indian state of Andhra Pradesh during vacation. "I have taken my campaign to 20 schools in Srikakulam. I want to reach out to schools in Abu Dhabi, too."
