A 17-year old boy, Udit Singhal (a resident of Delhi), was inspired to know why does a kabadiwala refuse to take the glass bottles after their use. During this research, he stumbles on to the fact that the glass bottles can be crushed in no time and turn them into a value-by-product.
His further exploration he found a firm in New Zealand, called Expleco Ltd that used to crush down the glass bottles. He contacted the New Zealand company over the phone and established a rapport with them over a short period. The name of this project is –"Zero Waste". The machine costs about 4000 dollars.
The crushing of bottles can reduce its volume about 90%. A bottle of beer (300 ml) can yield 263 gm of sand while a champagne bottle (750 ml) can produce about 838 gm of sand. The sand produced is very safe to use in brick making, road repair and it is stronger than the sand that is usually used for construction. This is high in silica content about 76% of silica which holds the brick and the concrete more firmly.
There are more ways to tackle the environmental problems around us , take the first step eventually you will land into where it leads to innovation.
