Exploring the science and engineering of new approaches to energy and waste reuse is both a very important and very interesting issue. There have been great efforts made to find potential materials, science, and technology for improvements in the reuse of energy and waste, to ensure energy sustainability and to increase the effectiveness and efficiency of engineering processes to achieve optimum energy production. Most of the efforts have been devoted to materials for photovoltaics, hydrogen production, batteries, and green energy. The range of materials of interest is very wide, from polymers to quantum dots. However, the engineering and environmental issues still present limitations, such as high energy demands, catalyst costs, and insufficient reuse or regeneration of spent adsorbents and catalysts. These challenges have opened new exploration of, for example, cheaper precursors, regeneration of spent adsorbents or catalysts, extraction of useful elements from waste, and overall optimization of engineering processes.
More recently, multifunctional and advanced materials have started to show promise for future applications. Integration of economical precursors, high performance materials, efficient methods, easy-to-use designs, and cost-effective manufacturing are always required for competitive energy production, and one would therefore expect clean energy that could address global warming to remain a major issue for many years. Development of alternative uses and reuses of by-products (waste) has also been of interest, not only to reduce the production of carbon dioxide, but also to achieve zero-waste policies. Overall, efforts are being made toward achieving high efficiency, economical or low-cost, renewable, and eco-friendly energy production.
Adsorption processes utilizing agro-waste as a simple method for removing heavy metals, pollutants, and odor from wastewater, are another important thread for environmental and industrial applications. Exploring new alternative adsorption processes and low-cost, highly efficient, and abundant adsorbents from agro-waste are being pursued for the further development of environmental applications that could remove or reduce a diverse range of hazardous pollutants and facilitate minimization methods for the management of waste on large a scale.
To address the above issues, the 3rd International Tropical Renewable Energy Conference (i?TREC) 2018, with the main theme of “Sustainable Development of Tropical Renewable Energy,” was held on September 6–8, 2018, at the Discovery Kartika Plaza, Bali, Indonesia. This conference was proudly organized by the Tropical Renewable Energy Center, Faculty of Engineering, Universitas Indonesia. The conference consisted of four symposia, including Smart Grids and Regulation, Bioenergy, Multifunctional and Advanced Materials, and Eco Tropical Built Environment.
