India, July 5 -- Perhaps it is the learning at engineering schools that sometimes sows small seeds of entrepreneurial thinking. Jayesh Pakhale was at the end of his mechanical engineering course at Sinhagad College and had to prepare to leave his hostel room. "When I was in the final year of my graduation, I found myself with a surplus of old college journals, books, and newspapers that I needed to dispose of. I set out to find a local "kabadiwala" in the market who could come to my place and collect all the scrap material at a fair price. Unfortunately, I was unable to find one. They all required me to transport the heavy 100kg+ material to their shop, which simply wasn't feasible."

That made him think. How did senior citizens, and work...
