The aim of this study was to investigate the bioenergy potential of greenhouse vegetable wastes like tomato, pepper, and eggplant wastes individually, in equal-mass binary mixtures, and in equal-mass ternary mixtures und...

Abstract Biochar yield prediction plays a critical role in optimizing pyrolysis processes and advancing sustainable biomass utilization. This study introduces a hybrid machine learning framework that integrates Decision ...

In the present study, the biochar produced by fast pyrolysis at 350 C of untreated and acid treated cellulose are evaluated as supports of CueRu@Pt core-shell nanoparticles (2.9 e3.5 nm) for the electro-oxidation of meth...

This study examines the fast pyrolysis of rosehip seed waste (RSW) in a fluidized bed reactor, evaluating its potential for syngas production and effective waste valorization. The fluidization behavior of sand/RSW mixtur...

Waste materials from agricultural and food packaging usage pose significant health and environmental challenges, where the main source of waste originates from plastics and protein-based amino acids, and their thermal de...

BackgroundTar-rich coals serve as an important coal-based oil and gas resource in China, while their pyrolysis product distribution is governed by the coupling effects of coal properties and reaction conditions. Therefor...

The extensive reliance on fossil resources for fuels and platform chemicals has raised critical concerns over resource depletion and increasing greenhouse gas emissions. To address these challenges, microalgae offer a pr...

Abstract The dual challenges of waste biomass disposal and escalating contamination by inorganic, organic, and emerging microplastic pollutants demand sustainable, circular remediation strategies. Biochar, a carbon-rich,...

ZnO nanorods (NRs) were grown on fluorine doped tin oxide (FTO) substrates at low temperatures (90 °C) from Zn2+ precursors in alkaline media previously seeded with ZnO nanoparticles. These were deposited onto the FTO s...

Catalytic fast pyrolysis of sunflower seed shells was performed using a two-stage fixed bed reactor to produce partially deoxygenated bio-oils. Ketonization and aldol condensation reactions were performed in a dual bed r...

"Four nickel-based catalysts are synthesized by wet impregnation and evaluated for the hydrotreatment/hydrodeoxygenation of beech wood fast-pyrolysis bio-oil. Parameters such as elemental analysis, pH value, and water c...

In this study, thin nickel oxide nanomembranes were obtained using thermal chemical spraying technology, which involves spraying a green-colored chemical solution at a rate of 30 sprays onto glass substrates with an area...

"The thermochemical decomposition of beech wood biomass results in a poor quality bio-oil, which cannot be directly used in diesel engines. In order to make this oil resemble liquid fossil fuels, an upgrading technique s...

"The growing concern about the increase in greenhouse gases and the consequences of these reached the point of having to resort to new and innovative technologies. In order to ensure the sustainable development of these ...

Abstract Accurate prediction of bio-oil yield from pyrolysis of organic solid waste is still the main problem in the field of biomass valorization, mostly because of high variability in the composition and the heterogene...

The co-production of bio-char and upgraded bio-oil by fast pyrolysis of raw and sulfuric-acid pretreated agro-industrial wastes (corn cob, sugarcane bagasse and sunfower seed hull) was investigated to valorize wastes as ...

ABSTRACT Phosphorus (P) is one of the nutrients that most limits agricultural productivity, especially in tropical soils. Enriched biochar has been proposed to increase the bioavailability of P and other nutrients in the...

Abstract In this study, we examined how substrate temperature affects the structural, morphological, electronic, and magnetic properties of nickel ferrite (NiFe2O4) thin films synthesized via spray pyrolysis. We investig...

This study aims to determine the comparison of oil yields obtained from processing HDPE plastic waste by comparing quantitatively and qualitatively the fuel oil produced. The processing of plastic waste into oil by pyrol...

Although significant progress has been made in using biochar for the removal of antibiotics such as tetracycline hydrochloride, challenges remain in improving its dispersion, surface reactivity, and adsorption efficiency...

In this study, thin films of cadmium oxide (CdO) were synthesized using the chemical thermal decomposition method. The films were deposited onto a glass substrate measuring 2.5 cm x 2.5 cm x 1 mm at a temperature of 400&...

Abstract Microplastics (MPs) have emerged as pervasive contaminants in surface and ground water systems worldwide, making it an increasing threat to ecosystem integrity and human health. Despite a rapid increase in resea...

Although soil C is a critical component of soil health, studies robustly exploring the agronomic and pedoclimatic effects on soil C are limited, especially at the landscape scale. Therefore, a dataset of 1490 topsoil ...
