Abstract: Lignocellulosic waste, such as date palm seeds, is treated with industrial waste such as rejected brine solution waste from a water treatment desalination plant to break down lignin and isolate and recover cellulose. Such a method is more cost effective and less toxic than other current and prior methods. Such a method concurrently solves two problems—usage of lignocellulose waste and usage of brine solution waste from a desalination treatment plant—to isolate and recover biocompatible, biodegradable versatile cellulose.

Abstract: A method for extracting lignin from lignocellulosic biomass using a non-choline chloride based natural deep eutectic solvent (NADES) formed from Citric Acid (CA) and Fructose (Fr) comprises mixing the biomass with the NADES, obtaining a lignin-NADES suspension, lyophilizing, rehydrating, and drying the suspension, and repeating the rehydration and drying steps to obtain lignin particles. The biomass used can be Ghaf biomass waste. The NADES preparation includes adding distilled water to reduce viscosity, mixing CA and Fr with distilled water in specific molar ratios of CA:Fr:distilled water of: 1:1:1, or 3:1:1, or 5:1:1, adjusting pH, stirring, and heating. The method also includes specific conditions for mixing, stirring, heating, and terminating the reaction. The lignin-NADES suspension is obtained through vacuum filtering and lyophilized by vacuum freeze-drying. The method avoids the use of acid-precipitation techniques, ensuring an efficient and environmentally friendly lignin extraction process.

Abstract: The present disclosure relates to an improvement in the process of hydrolysis of cellulose to produce nanocellulose using imidazolium-based ionic liquids with short alkyl chains in the presence of transition metal complex and an oxidizing agent.

Abstract: A method for processing a salt solution together with carbon dioxide is disclosed. The method comprises: extracting lignin from biomass; and treating the salt solution with the lignin residue and the carbon dioxide.

Abstract: The biodegradable composite insulation material is made from date palm leaf fibers and powdered okra. The date palm leaf fibers have a concentration of between 50 wt % and 90 wt % of the biodegradable composite insulation material, and the powdered okra has a concentration of between 10 wt % and 50 wt % of the biodegradable composite insulation material. The biodegradable composite insulation material is prepared by mixing date palm leaf fibers and powdered okra, in the above concentrations, to form a mixture. This mixture is then wetted with water, added to a mold, and heated under pressure to form a compressed article. The compressed article is then dried to form the biodegradable composite insulation material.

Abstract: A thermal insulating material made from date palm surface fibers and a method of manufacturing the thermal insulating material using waste material from the date palm tree is provided. The thermal insulating material includes date palm surface fibers and polyvinyl alcohol. The method may include softening date palm surface fibers (DPSF), drying the DPSF, infusing the DPSF with polyvinyl alcohol (PVA), and casting the PVA infused DPSF to produce the thermal insulating material made from date palm surface fibers. The thermal insulating material has a low thermal conductivity, demonstrating its suitability to insulating structures.
