They believe that the tamarind-shell nanosheets, when scaled up, could be an eco-friendly alternative to their industrially produced counterparts, and cut down on waste at the same time.

Cleaner production of tamarind fruit shell into bio-mass derived porous 3D-activated carbon nanosheets by CVD technique for supercapacitor applications. Chemosphere , 2021; 282: 131033 DOI: 10. ...

The scientists started by washing tamarind shells that were obtained as waste from the food industry, after which the shells were dried at a temperature of 100 ºC (212 ºF) for about six hours.
