Technological innovations, global climate concerns, and the overuse of fossil-based feedstocks for energy and chemicals have driven the demand for viable, sustainable alternatives for value-added chemicals and fuels production. Recently developed industrially relevant bioenergy c [....] » Read More
Biomass-derived 5-hydroxymethylfurfural (HMF) is a key platform molecule for the sustainable production of 2,5-furandicarboxylic acid (FDCA), a promising renewable alternative to petroleum-derived terephthalic acid. However, efficient FDCA production commonly relies on noble-me [....] » Read More
Anaerobic digestion is a well-established technology that recovers energy and nutrients from organic wastes. However, the effectiveness (and hence the economic viability) of biogas production depends strongly on the efficiency of biomethanation. It is well kno [....] » Read More
The production of syngas through biomass gasification has attracted considerable attention due to its potential to promote circularity, enhance sustainability, and address emerging needs, including those driven by socio-political events, to improve energy self-sufficiency. N [....] » Read More
Biomass is a renewable source of energy that includes biodegradable matter of plant and animal origin, in which solar energy is stored through the process of photosynthesis. The process of producing biofuels from biomass involves a range of diverse conversion methods, which depen [....] » Read More
Bioenergy is the largest source of renewable energy nowadays. Multitude of biomass feedstocks can be used to produce electricity, heating houses, biofuels for transportation, and supplying process heat for industrial facilities. Biomass residues and waste are potentially major co [....] » Read More
Waste printed circuit boards (WPCBs) represent a significant secondary resource of carbonaceous materials; however, their recycling is challenged by the presence of brominated flame retardants and toxic organic compounds. This study explores the catalytic valorization of metal-fr [....] » Read More
This work introduces a novel two-stage continuous fermentation process for converting industrial waste CO2 into omega-3 fatty acids and biodiesel. In the first anaerobic stage, bacteria convert CO2 into acetic acid (~3%), which acts as an intermediate carbon source. In the second [....] » Read More
Title : Hydrogen production from contaminated residual biomass: An integrated gasification and SEWGS process study
Enrico Paris, CREA-IT, Italy
The restoration of heavy metal-contaminated soils through Plant-Assisted BioRemediation (PABR) represents a sustainable environmental strategy, yet it generates a significant secondary waste stream: contaminated biomass that requires specialized disposal. This study investigates [....] » Read More
Title : Application of vanadium and tantalum single-site zeolite catalysts in heterogeneous catalysis
Stanislaw Dzwigaj, Sorbonne University, France
The metal ions well dispersed at zeolite framework are considered to be active sites of catalytic processes. Therefore, the incorporation of these metals into zeolites as isolated tetrahedral sites appears to be the important task. We have earlier shown that the incorporation of [....] » Read More
Title : Green management of enterprises as a response to climate change
Dai Yeun Jeong, Asia Climate Change Education Center, Korea, Republic of
Since industrialization was promoted in the 18th century, the enterprises focused on maximization of profit without considering nature being polluted and/or destructed in the process of resource extraction, production and distribution of goods and services. This is termed traditi [....] » Read More
