Reimagine waste jackfruit

NXplorers students in India found a way to turn waste jackfruit into biofuel.

NXplorers students in Sri Ramakrishna High School, India, reimagined the use of waste jackfruit to develop an energy solution that would create an economic alternative for farmers, and lead to a cleaner, greener environment.

Up to 40 per cent of the food produced in India is either lost or wasted*. Even though India is the largest jackfruit producer in the world, only a small amount is used. Most of the fruit is left to ripen and spoil. Not only does this cause a lot of food wastage, it means that farmers make less money, and it also has a negative effect on health as the rotting fruit increases the risk of diseases spread by mosquitos.

The NXplorers students came up with the idea to reimagine waste jackfruit as an alternative fuel and rethink waste in their communities. Their idea was firmly rooted in driving a sustainable change that would support farmers to switch to an eco-friendly fuel option. These are the steps they followed…

Repurpose jackfruits

The students observed that their locality had a lot of jackfruit trees. During the rainy season, they would see countless jackfruits being left to rot. They had neither the technology nor time on their hands to be able to harvest them effectively. They observed that the abandoned jackfruits eventually ended up in a rotten state, which also attracted mosquitos and other pathogens, making the area more prone to dangerous diseases. Due to abandoned jackfruits rotting away, pathogens found their way into the farmlands. To keep the pathogens away, the farmers started actively using a lot of harmful chemicals and strong pesticides. Our NXplorers students wanted to repurpose the waste jackfruit to stop this vicious cycle from repeating itself.

Reinvent the solution

Using the NXplorers toolkit and NXthinking methodologies, the students were able to finalise a solution – they decided to produce ethanol from jackfruit. The students factored in various aspects, like practicality, scalability, scope and functionality of their idea. Taking part in the NXplorers programme enabled them to apply their problem solving and critical thinking skills in real life and find solutions to their day-to-day problems.

Recreate biofuel

Through the process of fermentation and distillation, bioethanol was created from the waste jackfruits. Bioethanol has a significant role to play as a biofuel, a fuel of the future, as it has immense potential to reduce the amount of carbon dioxide emissions.

Rethink waste in communities

Some of the NXplorers students grew up in households that had always worked closely to maintain ecological balance. Due to many of their parents being involved in agriculture, they were extremely aware of the problems within the community environment and the need to develop solutions together. By developing a biofuel from waste jackfruits, the students helped their local community to rethink waste and see how it could be made useful again, fostering a culture of conservation at the same time.
