While studying at Jadavpur University, Banerjee wanted to find a creative and socially beneficial alternative to bricks. Along with his classmates, Banerjee created, a social enterprise called Qube in 2017. Its product is the Plastiqube-an alternative brick made from waste plastic.

Banerjee and his team work with waste collectors to gather garbage, including water bottles and abandoned bags. The garbage is then cleaned, cut up and pressed into blocks by hand. “Each Plastiqube brick costs 5 to 6 rupees (about 8 cents) to make,while the average clay brick sells for about 10 rupees (14 cents),” Banerjee says. What 's more, unlike traditional bricks, Plastiqubes don' t use any mortar (砂浆). “They are basically like Lego bricks,” explains Banerjee, now aged 22. He adds,“There are interlocking designs on the bottom and the top, and they lock between each other.

India is estimated to throw away over 25, 000 tons of plastic waste every day. Around 40% of it is left uncollected. “We’re building something sustainable (可持续的) out of garbage,” Banerjee says. By taking coal and mortar out of the brick making process, Banerjee claims Plastiqubes can reduce energy use by 70 percent, generating a much lower carbon foot-print than traditional bricks.

Each Plastiqube brick contains 1.6 kilograms of waste plastic. They haven't yet been tried out for practical purpose but tests on their fire resistance and long- term steadiness are now in progress. Banerjee believes they will last even longer than traditional clay bricks, while removing waste plastic from the environment for centuries.

Banerjee's innovation has, already won him recognition. He was a regional finalist for the United Nation's 2018 Young Champions of the Earth awards. He is also part of the Yunus and Yunus Global Fellowship. Banerjee will not only encourage young engineers to dream big, but also to think carefully about the environmental impact. “My advice is to start something while keeping a goal that it has to be sustainable in the long term,” he says.
