In the past, the occurrence of macro alga Ulva lactuca on the coastal areas of Jeju Island, Korea, has resulted in the expansion of devastating green tides, thus affecting coastal sustainability, aesthetic appearances, and tourism activities. This paper proposes a new strategy to investigate the potential of Ulva lactuca as a tribopositive layer for green energy harvesting in TENG applications.

In our study, the mixture of cellulase and pectinase were used to exploit plant matrix. The combination of these enzymes increased the extraction efficiency compared to single enzyme treatment. The fresh tea leaves, byproduct of the green tea processing, were utilized as materials for extracting. And the enzyme-assisted extraction was investigated. Firstly, the materials were treated with the mixture of cellulase and pectinase.

natural fiber for the construction of hybrid bio-composites. In the current research project, a thorough analysis of the use of soy-PF resin for the creation of composites reinforced with jute was conducted. A novel and practical cutlery material was created after the mechanical properties were evaluated and optimized. In order to study the value addition of these newly proposed biocomposite materials as an ecological alternative in terms of natural resources versus synthetic resources, variables such as hardness, cytotoxicity, and degrading qualities of composites were also explored.
