“…Hydrothermal treatments (HT) are thermochemical processes occurring at medium temperature and high pressure in the presence of water as solvent/reagent in sub and supercritical states. , The hydrothermal liquefaction process has been successfully applied in the chemical recycling of plastics to produce monomers, chemicals, and fuels . The recycling of cellulose acetate by thermochemical processes was already addressed by many authors, especially the pyrolysis of cigarette filters which are mainly made of cellulose acetate with the aim of producing chemicals, fuels, and porous carbon material. − Pyrolysis of cigarette butt filters was investigated by Jankovic et al for the production of porous char having characteristics of a macroporous material with developed mesoporosity suitable to be used in wastewater treatments . The thermochemical degradation of cellulose acetate by HT is poorly investigated, Combs and Woodstone filed a patent on the recovery of a general cellulose acetate waste by hydrolysis in the presence of a hydrolyzing agent, acetic acid, to obtain valuable products such as glucose molecules and reduce the amount of solid which needs to be landfilled .…”

Cellulose acetate waste from eyewear industry is produced in considerable amounts, and its biodegradability is not straightforward due to the presence of plasticizers and the slow kinetics of deacetylation reactions. In this work, the chemical recycling of cellulose acetate waste coming from eyewear industry is proposed through hydrothermal treatment with the aim of acetic acid and diethyl phthalate recovery. Cellulose acetate was first characterized to determine the acetylation degree which was measured to be 2.45 and the amount of diethyl phthalate which was 30% by weight. Hydrothermal tests were performed in batch 10 mL reactors studying the influence of temperature (190−250 °C) and reaction time (10− 240 min). The products were characterized by gas chromatography− mass spectrometry and Fourier transformed IR analysis, in order to determine the acetic acid and diethyl phthalate recovery percentage. The maximum recovery of acetic acid, 90%, was obtained at 250 °C for a reaction time of 30 min; in these conditions, the diethyl phthalate extracted was about 20% by weight, which is 65% of recovery. The diethyl phthalate undergoes a hydrolysis reaction at high temperatures and long reaction times, decreasing its recovery degree. The diethyl phthalate is recovered mainly in the liquid phase extracted with ethanol and for 210 °C and 60 min and 190, 240 min it is almost pure (>97%), with a recovery efficiency of 87%. Cellulose decomposition products, mainly 5-(hydroxymethyl)furfural, were detected in the liquid products with an increase raising the reaction temperature and time. Aspen Plus simulation was performed in order to figure out the whole process including the separation of the products; a preliminary energy balance indicates that combustion of the solid residue can contribute to lower the energy required for the process, which results in 800 MJ/h for a plant capacity of 10 ton day −1 .

“…In the context of the growing global energy demand and concerns about climate change, the development of sustainable and environmentally friendly technologies for energy conversion and production is of paramount importance [1]. One such technology gaining attention is the dry reforming of methane (DRM), a process that converts methane (CH4) and carbon dioxide (CO2) into syngas, a valuable mixture of hydrogen (H2) and carbon monoxide (CO) [2].…”

The utilization of non-noble metal catalysts for the dry reforming of methane (DRM) has gained significant attention in recent years due to the increasing demand for clean and sustainable energy sources. DRM involves the conversion of methane (CH4) and carbon (IV) oxide (CO2) into synthesis gas (syngas), a valuable mixture of hydrogen (H2) and carbon monoxide (CO). Commercialization of non-noble metal catalysts for this reaction presents several challenges that must be addressed to achieve practical implementation. This short review discusses the challenges, opportunities, and future directions of non-noble metal catalysts for DRM. First, the limitations associated with the intrinsic activity and stability of non-noble metals, such as nickel, cobalt, and iron, are explored. Enhancing catalyst performance through compositional modifications, the incorporation of promoters and supports, are ways to overcome these challenges. Directions that hold promise for advancing non-noble metal catalysts in DRM, including the advanced exploration of bimetallic catalysts for synergistic effects, and the integration of non-noble metals into novel catalytic systems, were among the future proposals, while non-noble metal catalysts have the potential to revolutionize the production of syngas and contribute significantly to the transition towards sustainable energy solutions.

“…Responsible Editor: George Z. Kyzas Linear economy generates huge quantities of waste in the aquatic and atmospheric environment. Hence, the scientific and industrial communities worldwide actively search for green approaches to decrease the quantity and hazardous of generated waste and their possible recycling (Nabgan et al 2023). The concept of "zero waste theory" is based on using green and recyclable products and valorizing natural and available resources (Romano et al 2019).…”

An exponential rise in global pollution and industrialization has led to significant economic and environmental problems due to the insufficient application of green technology for the chemical industry and energy production. Nowadays, the scientific and environmental/industrial communities push to apply new sustainable ways and/or materials for energy/environmental applications through the so-called circular (bio)economy. One of today’s hottest topics is primarily valorizing available lignocellulosic biomass wastes into valuable materials for energy or environmentally related applications. This review aims to discuss, from both the chemistry and mechanistic points of view, the recent finding reported on the valorization of biomass wastes into valuable carbon materials. The sorption mechanisms using carbon materials prepared from biomass wastes by emphasizing the relationship between the synthesis route or/and surface modification and the retention performance were discussed towards the removal of organic and heavy metal pollutants from water or air (NOx, CO2, VOCs, SO2, and Hg0). Photocatalytic nanoparticle–coated biomass-based carbon materials have proved to be successful composites for water remediation. The review discusses and simplifies the most raised interfacial, photonic, and physical mechanisms that might take place on the surface of these composites under light irradiation. Finally, the review examines the economic benefits and circular bioeconomy and the challenges of transferring this technology to more comprehensive applications.
