“…Green energy conversion and storage are emerging needs toward a sustainable future. The conversion of source-abundant biomass to value-added chemicals has been one of the feasible solutions. − 5-Hydroxymethylfurfural (HMF), a typical biomass platform chemical originated from the dehydration of glucose, has aroused extensive attention owing to its broad applications in the production of pharmaceuticals, agrochemicals, and monomers . Among them, 2,5-furanedicarboxylic acid (FDCA), derived from the oxidation of HMF, can be polymerized into poly(ethylene 2,5-furanedicarboxylate), which is an environmentally friendly replacement to petroleum-derived products like poly(ethylene terephthalate). , …”

5-Hydroxymethylfurfural oxidation reaction (HMFOR) is regarded as a promising approach to attain biomassderived high-value chemical products. As the HMFOR process is complicated, and the two-step oxidation of the aldehyde group and hydroxyl group in 5-hydroxymethylfurfural (HMF) is typically involved, it is fundamentally significant to understand the different catalytic processes for HMFOR. In this work, we identify direct and synergistic oxidation types for HMFOR on cobalt oxide catalysts. For the direct HMFOR process, Co 3 O 4 was found to have a higher activity for the aldehyde group than for the hydroxyl group due to the higher reaction barrier of hydration in the hydroxyl oxidation. By studying the hydroxyl oxidation behaviors in transition metal oxides, NiO exhibited optimal hydroxyl activity owing to the appropriate OH adsorption energy for alcohol dehydrogenation. Therefore, the optimal HMFOR performance was achieved by accurately introducing Ni into the tetrahedral catalytic sites of cobalt spinel oxides to improve the hydroxyl activity. The integrated catalytic sites enhanced the overall activity of HMFOR with 92.42% FDCA yield and 90.35% faradaic efficiency. This work provides a promising perspective for designing efficient electrocatalysts for HMFOR.

“…The bioeconomy focus on recovery of waste biomass in integrated, multi‐output production chains, optimizing their value over time (Stegmann et al., 2020). Idea for biorefineries was derived for the treatment of waste and wastewater, and can be best result in maintaining social, ecological, economic and long term sustainable hurdles that can be good option for GHG emission reduction and implementation of techno‐economic analysis (TEA) of biorefineries as well as life cycle assessment (LCA) methodologies may assess sustainability (Lopes et al., 2020).…”

The world is facing a severe energy crisis due to rapid industrialization, population explosion, and modern lifestyle. Conventional energy sources are running out of stock and accordingly, an ardent need for the search for alternative feedstock for energy recovery has been the research focus for the past few decades. In context to this energy turmoil, the lignocellulosic biomasses have emerged as an excellent surrogate antecedent for energy procreation in this present scenario of the energy crisis. Among numerous feasible biomass energy recovery methods, the biochemical route and the thermochemical route are the most prevailing. Accordingly, several biomass characteristics require well understanding to access the extent of possible energy recovery. The compositional features assessed (in terms of cellulose, hemicellulose, extractives, and lignin content) as well as the ultimate analysis carried out (in terms of the carbon, hydrogen, oxygen, sulfur, and nitrogen content) as one of the major parameters for evaluating the energy recovery potential and subsequently, a Van Krevelen diagram was obtained to define their energy recovery potential. The calorific value of the three biomass specimens obtained by using an adiabatic bomb calorimeter and subsequently, their oil equivalence was presented. A tariff and budgetary analysis evaluated to define their respective economic incentives and their potential scope to meet the energy crisis scenario. Finally, a scoring matrix analysis conducted parallelly by evaluating the various parameters by adopting the rank correlation method to screen out the best biomass category. The overall scheme of study adopted for screening a particular waste biomass category from three widely available agriculture waste biomass samples (rice husk, corn cob, and nutshell) through multiple criteria and thereby evaluating the most ideal biomass as the surrogate source to meet the ever‐increasing energy demand which are prevalent in the state of Jharkhand, India.

“…However, the recent changes in the view of the economy as circular [ 3 ] renders the determination of some materials as wastes very complex and never straightforward [ 10 ]. Some materials called wastes in the past, e.g., organic fractions of municipal wastes, agriculture leftovers, etc., lost their attributes as they became relevant feedstocks for the energy and fine chemical sectors [ 11 ]. The food wastes bring another uncertainty in terms of definition.…”

Plastic can be used for many things and at the same time is the most versatile material in our modern world. However, the uncontrolled and unprecedented use of plastic comes to its end. The global ban on plastic brings significant changes in technology but even more so in civil perception—changes taking place before our eyes. The aim of this study was to find answers to the questions about the readiness of consumers for a global ban on plastic. Within the research, the differences in consumer acceptance in countries in Europe, South and North America and Asia and the expression of social readiness to change attitudes towards plastic food packaging were analyzed. This work sketches the legal framework related to limiting the use of one-use food packaging made of fossil raw materials at the level of the European Union, Poland and Portugal but also at the level of the two largest economies in the world, China and the United States, as well as lower-income countries, e.g., Ukraine and Brazil. The survey results were analyzed using descriptive and inferential statistics. The performed study demonstrates that, in in all the surveyed countries, appropriate legal acts related to the reduction of plastic in everyday life are already in place. Furthermore, this work demonstrates the full understanding of plastic banning in all surveyed countries. Consumers are aware that every effort should be made to prevent the world from drowning in plastic waste. Society is, in general, open to the use of bioplastics produced from the second-generation resource if second-generation bioplastics contribute to environmental and pollution reduction targets.
