    Acidic Magnetic Biocarbon-Enabled Upgrading of Biomass-Based Hexanedione into Pyrroles

    Zhimei Li1, Kuan Tian2, Keping Wang2, Zhengyi Li2, Haoli Qin1,*, Hu Li2,*

    Journal of Renewable Materials, Vol.11, No.11, pp. 3847-3865, 2023, DOI:10.32604/jrm.2023.030122

    Abstract Sustainable acquisition of bioactive compounds from biomass-based platform molecules is a green alternative for existing CO2-emitting fossil-fuel technologies. Herein, a core–shell magnetic biocarbon catalyst functionalized with sulfonic acid (Fe3O4@SiO2@chitosan-SO3H, MBC-SO3H) was prepared to be efficient for the synthesis of various N-substituted pyrroles (up to 99% yield) from bio-based hexanedione and amines under mild conditions. The abundance of Brønsted acid sites in the MBC-SO3H ensured smooth condensation of 2,5-hexanedione with a variety of amines to produce N-substituted pyrroles. The reaction was illustrated to follow the conventional PallKnorr coupling pathway, which includes three cascade reaction steps: amination, loop closure… More > Graphic Abstract

    Valorization of Aloe barbadensis Miller. (Aloe vera) Processing Waste

    Jeltzlin Semerel1, Nigel John1, Wim Dehaen2, Pedro Fardim3,*

    Journal of Renewable Materials, Vol.11, No.3, pp. 1031-1061, 2023, DOI:10.32604/jrm.2022.023449

    Abstract Aloe vera plant is known worldwide for its medicinal properties and application in gel-based products such as shampoo, soap, and sunscreen. However, the demand for these gel-based products has led to a surplus production of Aloe vera processing waste. An Aloe vera gel processing facility could generate up to 4000 kg of Aloe vera waste per month. Currently the Aloe vera waste is being disposed to the landfill or used as fertilizer. A sustainable management system for the Aloe vera processing waste should be considered, due to the negative societal and environmental impacts of the currents waste disposal methods. Therefore, this… More > Graphic Abstract

    Review of Cellulose Smart Material: Biomass Conversion Process and Progress on Cellulose-Based Electroactive Paper

    S.H. Hassan1,2, Lee Hwei Voon1*, T.S. Velayutham2*, Lindong Zhai3, Hyun Chan Kim3, Jaehwan Kim3

    Journal of Renewable Materials, Vol.6, No.1, pp. 1-25, 2018, DOI:10.7569/JRM.2017.634173

    Abstract Cellulose is a renewable biomass material and natural polymer which is abundantly available on Earth, and includes agricultural wastes, forestry residues, and woody materials. The excellent and smart characteristics of cellulose materials, such as lightweight, biocompatibility, biodegradability, high mechanical strength/stiffness and low thermal expansibility, have made cellulose a high-potential material for various industry applications. Cellulose has recently been discovered as a smart material in the electroactive polymers family which carries the name of cellulose-based electroactive paper (EAPap). The shear piezoelectricity in cellulose polymers is able to induce large displacement output, low actuation voltage, and low… More >
