"The solution is innovative, combining portability with solar power, making it practical for areas with unreliable electricity."

"This idea tackles the serious issue of plastic waste from everyday products. It’s a smart and practical step toward a cleaner planet."

"Very innovative, and the portability aspect is great. A question: how many markers can you reliably test in parallel on a paper strip before the signal gets messy? Scalability might run into technical constraints."

"The project aligns well with sustainable development goals. It’s a great example of turning waste into value—something industries are increasingly looking for."

"Amazing concept — using AI and financial math to make sense of hidden signals most people ignore."
