The literature lacks information on how the final slow pyrolysis temperature and Amazonian Forest wood species impact charcoal's physical, chemical, and energetical properties. Thus, this study aimed to evaluate the effect of wood species and final slow pyrolysis temperatures on the charcoal quality for the Brazilian steelmaking industry. Wood wast...

This study aimed to design a sequential biorefinery from wine-making by-products for the obtaining value-added products, focusing on extracting natural pigments and the evaluation of bioenergy produced by remaining biomass from Carm´en`ere Grape Residues (CGR) through slow pyrolysis. To achieve these goals, solid-liquid extraction of pigments from ...

Food loss and waste, about 30% of human-consumable food production, pose challenges to safety, the economy, and the environment. A significant portion includes discarded fruit parts, notably seeds. Pequi fruit seeds contribute to agro-industrial waste due to their intricate structure and thorns, raising environmental concerns. Prior research shows ...

Avec le soutien d’une unité du CNRS de Montpellier, une équipe de recherche de l’Université de Pau et des Pays de l’Adour (UPPA) s’intéresse à la valorisation de la balle de riz, la cosse qui entoure ces petits grains bien connus. Leurs objectifs ? Récupérer bio-huile et silice, deux super ingrédients présents dans ce déchet, qui pourraient servir ...

Slow pyrolysis can be used to convert residual agricultural biomass into energy-dense biochar along with its by-product, pyrolysis liquid, for diverse applications. Due to its high concentration of bioactive chemicals, pyrolysis liquid has gained interest as a potential wood protectant. This study aims to evaluate the efficacy of slow pyrolysis liq...

This study employed numerical modeling to investigate the reactivity and kinetics involved in the slow pyrolysis of lignocellulosic biomass. The model integrates a biomass multi-step kinetics scheme with heat, momentum, and mass transfer, and it was based on the transport of species and flow in a porous medium approach. To develop the multi-step ki...

Cashew nut shells (CNS), as non-edible agricultural residues produced by cashew nut shelling units, are largely abundant in West Africa. They present a strong potential for energy production although the presence of specific extractives known collectively as cashew nut shell liquid (CNSL) is problematic. These extractives can account for up to 40 %...

Pétrification est un procédé de transformation de cellulose en roche, permettant d’envisager un artisanat céramique à la mise en forme simple, à partir de papier, corde, coton, bois ou carton. Il se décline en deux étapes : l’infusion d’une solution de silice dans le modèle, suivie d’une pyrolyse sous atmosphère. Lors de cette cuisson, le carbone e...

In Senegal, biomass fuels and more specifically pellets from agricultural residues have attracted interest in recent years. These fuels are eco-friendly materials and represent a better alternative to domestic fuels such as charcoal or firewood due to their availability at local scale associated to their relative uniformity (standard size, possible...

This research assessed the relationship between wood physical-anatomical variables and charcoal physical–mechanical properties. Nine trees were harvested and mechanically processed into standard pieces for laboratory analysis. The following variables were determined: wood density, fiber length and width, fiber lumen diameter and wall thickness, fib...
