The global supply chain has been growing strongly in recent years. This development brings many benefits to the economy, society, and human resources in each country but also causes a large number of concerns related to the environment since traditional logistics activities in the supply chain have been releasing a significant amount of emissions. For that reason, many solutions have been proposed to deal with these environmental pollution problems. Among these, three promising solutions are expected to completely solve environmental problems in every supply chain: (i) Application of blockchain in the supply chain, (ii) Use of renewable energy and alternative fuels, and (iii) Design of a closed supply chain. However, it seems to lack a comprehensive study of these solutions aiming to overcome the drawbacks of traditional logistics. Indeed, this work focuses on analyzing and evaluating the three above-mentioned solutions and the impacts of each solution on solving problems related to traditional logistics. More importantly, this work also identifies critical factors and challenges such as policies, laws, awareness, and risks that are found to be remarkable difficulties in the shifting progress of traditional logistics to green logistics. Finally, directions for developing and deploying green solutions to the logistics, supply chain, and shipping sectors toward decarbonization strategies and net-zero goals are discussed in detail.

Though food scarcity realizing in many places in the world, food waste generation still shows its increasing trend because of cultural and habitual changes, as well as technological characteristics. However, food waste comprises a large amount of organic material and biodegradable components, showing that it could be a potential source for producing hydrogen (H 2) aiming to satisfy the key goals of diversifying the energy supply and reducing environmental pollution. Indeed, this research addresses the potential possibilities to use food waste for the production of H 2 by using a water gasification reactor. In this work, food waste was gasified by varying the operating parameters in the H 2 production process and the addition of additives. In this investigation, different additives such as HCl, NaCl, and NaHCO 3 were considered to investigate at different reactor temperatures like 300, 350, and 400 °C for different reaction durations like 30, 45, and 60 min. The results revealed that the best average yields of CH 4 , H 2 , CO 2 , CO, and total gas were obtained as 1.5, 12.9, 0.2, 0.1, and 13.9 mol/kg, respectively, when the reaction employed with NaHCO 3 additive than the other cases (with HCl, NaCl additives and no additive cases). The H 2 production efficiency was estimated as 43%, 34%, 27%, and 30% when the use of NaHCO 3 , NaCl, HCl, and no additives. Hence, it is found that the NaHCO 3 catalyst considerably enhances the gasification process through the improvement of the water-gas shift reaction, and thereby H 2 production increases. [Display omitted] • Hydrogen Production from food waste possibilities were experimentally analyzed. • HCl, NaCl, and NaHCO 3 Alkaline metals additives tested in H 2 production. • Analyzed influence of reaction temperature and reaction duration in H 2 production. • NaHCO 3 additive with food waste, improves the water-gas shifting reaction. • NaHCO 3 additive recorded 12.9 mol/kg H 2 production & production efficiency 43%.
