Sustainable Materials and Technologies

Coconut husk (CH), a solid biowaste derived from coconut, is typically used in household items, such as doormats. Recent studies have shown that CH is rich in lignocellulose, which can make for energy-related applications of CH. To this end, a global team of researchers, in a new study, make use of CH to develop self-powered energy storage and harvesting devices, achieving high energy density and output performance, and opening doors to a circular economy.
