Abstract

Nanocellulose, a sustainable and biodegradable material derived from natural cellulose, holds immense potential for addressing global environmental challenges. This article reviews the production methods, structural modifications, and applications of nanocellulose derivatives in environmental contexts, emphasizing their role in water purification, pollutant adsorption, and renewable energy solutions. The systematic literature review highlights the unique properties of nanocellulose, such as high mechanical strength, large specific surface area, and tunable chemical functionalities, which enable its use in various industrial, biomedical, and environmental applications. Results indicate that nanocellulose-based materials outperform conventional materials in efficiency and sustainability, particularly in water treatment and biodegradable packaging. Despite its advantages, challenges remain, including production costs, dispersibility in polymer matrices, and stability under high humidity. These limitations necessitate further research and collaborative innovation to enhance its applicability and affordability.

Abstract

In the face of climate change challenges and declining fossil energy resources, bioethanol is emerging as an environmentally friendly renewable energy solution. This article aims to review the potential, opportunities, and challenges in utilizing agricultural waste as the main raw material for bioethanol production. By analyzing various recent studies, it is found that agricultural wastes such as rice straw, corn cob, and bagasse have significant carbohydrate content for conversion into ethanol. Second-generation bioethanol production technologies utilizing lignocellulose offer higher efficiency than previous generations but face technical and economic challenges, including complex pretreatment requirements and high production costs. This review shows that bioethanol utilization can reduce dependence on fossil fuels while providing a sustainable solution for waste management. Policy support, technological innovation, and cross-sector collaboration are needed to accelerate the development of agricultural waste-based bioethanol, especially in developing countries such as Indonesia.
