- Contribution of sustainable fuels for the future of the energy sectorPublication . Serralha, F. N.; Dias, Nilmara; Duarte, Raquel; Borges, Rui PedroThe main driving forces of the development of alternative energy are growing energy demand combined with the search for energy independence and environmental issues, such as global warming. Throughout this chapter, the sustainability of the currently most used alternative fuels, their characteristics, applica- tions, global consumption, and demand data will be discussed. The different strategies and policies for the adoption of renewable energies also will be discussed. Fuels are compared by their contributions to the development of the circularity of the energy sector, by the feedstock and process efficiency. The advantages, disadvantages, and barriers that each one presents are evaluated to better understand which are the most promising and how their production and consumption can be increased. The aim of this chapter is to present the potential alternative fuels within their applications and analyze their contribu- tion to make the energy sector more circular and sustainable.
- Mini-Project of Ethanol Production from Waste as a Teaching MethodologyPublication . Dias, Nilmara; Carvalho, Teresa; Reis, Alexandre L. S.; Serralha, F. N.The development of sustainable alternative fuel, energy and chemical products is happening all over the world. Some of the main reasons for this increase are the increasing demand for fuel and energy due to population growth and economic development; climate change and the need for decreasing greenhouse gas (GHG) emissions; enhancement of waste recovery efforts to redirect waste away from landfills and decrease the reliance on primary raw materials. Thus, it is important to make students aware of these aspects and explore the development of alternative fuels, while giving them the tools to be creative and autonomous. The aim of this paper is to show how the implementation of a mini-project can improve not only students’ knowledge about the production of a biofuel from waste, but also their development of the theoretical and basic skills needed to carry out the mini-project. This paper presents in addition to the methodology used, some results to the implementation of the mini project, specifically the students’ points of view.
