At The Age of 15 She Invented Building Material From Indian Rice Waste

After seeing the environmental hazards that burning rice waste was causing at her family farm in North India, then-15 year old Bisman Deu saw an opportunity to create something useful, and developed an environmentally sustainable building material out of the farm’s biggest waste product.
She’s 18 now, and finishing school in Chandigarh, but Deu is on a journey with her product, Green Wood, as it becomes more relevant now than ever before.

To understand Deu’s product, one needs to understand the levels of dire pollution that the entire North India region suffers as a result of two major burning seasons for farmers. The first round is in May, during the heat of summer when wheat chaff is burnt and rice crops are sown, and the second in November when rice paddy is burnt and wheat crops are sown.
Deu’s family farm in the North Indian city of Amritsar grows both wheat and rice.
After seeing the burning of the waste products during evening walks with her dad, Deu, who had moved back to India with her family after spending most of her formative years in the U.K., realized that everyone around her was suffering from breathing problems as the air clouded over with the smoke.
“I started researching pollution,” she says, “then I researched the properties of rice husk; it has a high silica content, is waterproof, and termite resistant,” she says.

With research in hand she went on to experiment in her mother’s kitchen, mixing the leftover rice husk with resin and baking it – to form a prototype product, which she named Green Wood. She saw this particle board forming the base building block for housing in rural communities.
“It’s affordable, sturdy,” she says, “instead of cutting wood.”
The idea is to reduce the amount of rice waste that is left for farmers to burn, thereby significantly reducing the levels of pollution that spread across the region.
With sustainability as a large part of the product’s promise, Deu chose to name her product ‘Green Wood’. “I’m actually pretty happy with the name,” she says, “it was a catchy name so I thought of going with it.”
After creating the initial prototype, Deu got two other students to join her in forming a team and they entered HP’s 2013 Social Innovation Relay competition which asked high school students to come up with innovative business products. Green Wood was chosen a winner out of 43,000 student entries globally.
In 2014, Deu was invited by UNICEF to be a keynote speaker and panelist at their State of the World’s Children event in New York.
She’s also currently the only young person on UNICEF’s Wearables For Good judging panel.
“I think these events have really helped me to grow as a person,” she says, adding that she wants to study economics before returning to her innovative entrepreneurial passion.
Alongside developing Green Wood, Deu has also created an initiative to promote entrepreneurship among girls.
“Girls in India are not really motivated to go into this [entrepreneurship] because there is a risk attached to it,” she says, “they want a nine to five job.”
With her Colour The World Pink endeavors, she hopes to begin to change the female mindset from a young age. “I want to teach kids the satisfaction of earning money,” Deu says.
Admittedly her product will take a couple more years to fully develop and market. “I would start with Chandigarh,” her home town, and then expand, she says.
“Compared to steel or regular wood, this will be pretty cheap,” says Deu.
Green Wood has already attracted company interest not only from across India, but also from places as far away as Ecuador.

And there are many examples of inspiring actions taken by CEOs and companies in support of their employees. But as we’ve come to recognize that this crisis will last more than a few short weeks, companies are now defining their approach for the long haul.
