Special Issue Information

Dear Colleagues,

Currently, rapid industrialization and economic development worldwide gives rise to ever-increasing energy demand and human population. Additonally, sustained population growth has led to the production of an enormous quantity of waste which needs proper management. One of the keys to confronting these challenges is to change our prototype about waste, whose prospective as an alternative energy resource further lead to low greenhouse gas emission and has been gaining significant consideration with the development of waste-to-fuel technologies (WtE). As a sustainable alternative, rather than considering unwanted things as waste, waste is being deliberated as a potential energy source via WtE technologies. With advanced WtE technologies, a diverse range of waste comprising sewage sludge, food waste, municipal waste, agricultural waste, and the like are converted into renewable and sustainable energy resources such as biodiesel, biogas, syngas, bio-oil, bioethanol, and so forth. Additionally, in the field of waste management, experimentation, process modeling and assessment analysis have emerged as the most pragmatic methods to understand the conversion, relevant aspects and ecological sustainability of the processes, services or product systems respectively.

This Special Issue on “Waste-to-Fuel, Process, and Its Applications” intends to invite novel research that addresses challenges in the wide-ranging area of waste-to-energy technologies, integrated waste conversion approaches, biorefineries, green energy and production of renewable, and sustainable energy. Topics comprise but are not constrained to the following:  

  • Waste-to-energy technologies;
  • Green energy production from waste products;
  • Process modeling/experimentation of conversion technologies based on waste;
  • Potential approaches and optimization of energy recovery from different waste resources;
  • Distinct application of green fuel (such as engines, fuel cells, and so on);
  • Greenhouse gas emission analysis from waste-to-energy approach;
  • Circular bio-economy and life cycle analysis;
  • By-product (fertilizer, metal recovery, etc.) from waste feedstock conversion.

Food waste remains a serious economic, environmental, and ethical problem, whether globally or at a national level. The hospitality industry is responsible for more than one-third of food waste. This study investigated the tackling of food waste in all-inclusive hotels from an employee perspective. It explored employees’ perceptions of the causes and driving factors behind food waste, and considered why food waste occurs, and how best to reduce waste to the minimum. A total of 47 semi-structured interviews were conducted with managers and chefs employed in all-inclusive hotels in Hurghada, Egypt. Critical insights that emerged from the findings include that guest behavior, background, and eating habits, along with the nature of the unlimited pre-paid services offered by all-inclusive programs, are the main drivers for food waste. Furthermore, the operation’s routine and the practices of all-inclusive hotels contribute to food waste, with a lack of technology employed to tackle food waste practices. In addition, inappropriate practices of all-inclusive hotel employees during the food service cycle contribute negatively to food waste. The low room rate package of all-inclusive hotels obliges hotel managers to purchase food raw materials of inadequate quality. Consequently, the final products are below guest expectations and increase the level of food waste. The findings also indicate that guest attitudes and preferences are perceived as key drivers of food waste. This research presents an examination of staff perspectives of the causes of food waste and how to effectively reduce it in the context of an all-inclusive resort. The results have theoretical implications and implications for practitioners. Full article
