Meet Pranav Sarma, a student at Artie Henry Middle School in Cedar Park, TX. Pranav recently competed against hundreds of students in the 2019 Austin Energy Regional Science Fair. For his project, Pranav focused on using biomass — a waste material from plants and animals such as wheat stalks or yard waste — to produce a renewable form of energy. His innovative project ended up winning a Best in Climate Protection award.
We spoke with Pranav about his commitment to Net-Zero, what his toughest challenges have been, and what advice he has for others.
My mom and grandma grew up in India, and they have told me lots of stories about how they used waste products — like cow manure and plant husks — for cooking and heating when they were little. This made me curious, and I wanted to measure the amount of heat and energy generated by combusting waste products to see if they could replace fossil fuels.
For my project, I collected various waste products like cow manure and banana peels. Then, I completely dried them out in the sun. Next, I measured the same amount of each material and used it to heat 500 mL of water. I measured the temperature of the flame and the water at one minute intervals until the material completely burned out. Based on the measurements gathered, I calculated the total amount of energy generated by each material, along with the maximum temperature reached by the flame.
The hardest part was figuring out whether the material was completely dry.
In completing my project, I was very excited to learn that we can potentially replace fossil fuels with renewable resources like cow manure, rice and wheat husks, and banana peels. These are all materials that might otherwise end up in a landfill, so it’s really a win-win.
We should all reduce our trash, reuse materials, and recycle. Every little thing we can do to reduce our carbon footprint helps. Some of the ways that I am doing my part include turning off my devices when I am not using them, turning off lights when I leave a room, and conserving water by turning off the tap when I brush my teeth. I also help my parents with composting food scraps like vegetables, fruit peels, coffee, and tea grounds. Our family also recycles, and I help by separating papers, cans, and cardboard boxes. I want to do my part because every little bit counts. We only have one Earth.
