    Peyman Ahmadi1,*, Davood Efhamisisi1,*, Marie-France Thévenon2,3, Hamid Zarea Hosseinabadi1, Reza Oladi1, Jean Gerard2,3

    Journal of Renewable Materials, Vol.12, No.10, pp. 1715-1728, 2024, DOI:10.32604/jrm.2024.054076 - 23 October 2024

    Abstract Sugarcane bagasse is an agro-waste that could replace timber resources for the production of bio-composites. Composite boards such as particleboard offer an issue for the use and recycling of poor quality timber, and these engineered products can overcome some solid wood limitations such as heterogeneity and dimension. Bagasse offers an alternative to wood chips for particleboard production but present some disadvantages as well, such as poor physico-mechanical properties. To address these issues, bagasse fibers were treated with an innovative natural resin formulated with tannin and furfural. Impregnated particles with different concentrations of resin (5%, 10%,… More > Graphic Abstract

    Slow Pyrolysis of Sugarcane Bagasse for the Production of Char and the Potential of Its By-Product for Wood Protection

    Febrina Dellarose Boer1,2,3, Jérémy Valette1,2, Jean-Michel Commandré1,2, Mériem Fournier3,4, Marie-France Thévenon1,2,*

    Journal of Renewable Materials, Vol.9, No.1, pp. 97-117, 2021, DOI:10.32604/jrm.2021.013147 - 30 November 2020

    Abstract Sugarcane bagasse was pyrolyzed using a laboratory fixed bed reactor to produce char and its by-product (pyrolysis liquid). The pyrolysis experiments were carried out using different temperatures (400°C and 500°C), heating rate (1 °C/min and 10 °C/min), and holding time (30 min and 60 min). Char was characterized according to its thermal properties, while the pyrolysis liquid was tested for its anti-fungal and anti-termite activities. Pyrolysis temperature and heating rate had a significant influence on the char properties and the yield of char and pyrolysis liquid, where a high-quality char and high yield of pyrolysis… More >

    Effect of Y-Methacryloxypropyltrimethoxysilane (MPS) and Tetraethoxysilane (TEOS) Towards Preparation of Oil Absorbent Foams from Polyvinyl Alcohol (PVA) Reinforced with Microfibrillated Cellulose (MFC)

    Dzun Noraini Jimat*, Sharifah Shahira Syed Putra, Parveen Jamal, Wan Mohd Fazli Wan Nawawi, Mohammed Saedi Jami

    Journal of Renewable Materials, Vol.8, No.7, pp. 739-757, 2020, DOI:10.32604/jrm.2020.010357 - 01 June 2020

    Abstract Increasing usage of foams in various industry sectors had causing serious disposal problems once it reaches the end of its life-cycle. Herein, PVA-MFC foam was prepared by freeze-drying using polyvinyl alcohol (PVA) and microfibrillated cellulose (MFC) as a reinforced material from sugarcane bagasse (SCB). In this study, the PVA-MFC foam was chemically silylated with Y-methacryloxypropyltrimethoxysilane (MPS) and tetraethoxysilane (TEOS). The wetting ability and mechanical strength of the silylated 2,20PVA-MFC foam was greatly enhanced compared with unmodified 2,20PVA-MFC foam. The silane chemicals (MPS and TEOS) had been confirmed grafted on 2,20PVA-MFC foam due to the presence of Si-C… More >

    Performance Comparison of Chemically Modified Sugarcane Bagasse for Removing Cd(II) in Water Environment

    Manh Khai Nguyen1,*, Minh Trang Hoang1,2, Thi Thuy Pham1, Bart Van der Bruggen2

    Journal of Renewable Materials, Vol.7, No.5, pp. 415-428, 2019, DOI:10.32604/jrm.2019.04371

    Abstract This paper evaluates the adsorption capacity of chemically sugarcane bagasses with sodium hydroxide (SHS), citric acid (CAS), tartaric acid (TAS) and unmodified sugarcane bagasse (SB) for cadmium adsorption in water environment. The results prove adsorption capacity for Cd (II) increases after chemical modification and the adsorption fits perfectly with the Langmuir isotherm. CAS had the highest maximum adsorption capacity of 45.45 mg/g followed by TAS with 38.46 mg/g and SHS with 29.41 at optimum pH 5.0 and 120 minutes equilibrium time while 1 g SB removed 18.8 mg Cd (II) in the same conditions.

    Isolation and Characterization of Nanocellulose Obtained from Industrial Crop Waste Resources by Using Mild Acid Hydrolysis

    Galia Moreno, Karla Ramirez, Marianelly Esquivel, Guillermo Jimenez*

    Journal of Renewable Materials, Vol.6, No.4, pp. 362-369, 2018, DOI:10.7569/JRM.2017.634167

    Abstract Cellulose, microcrystalline cellulose and nanocellulose were prepared from three agricultural waste resources: pineapple leaf (PALF), banana rachis (BR), and sugarcane bagasse (SCB). Each waste resource was first converted into microcrystalline cellulose which was subsequently converted into cellulose nanoparticles by using mild (30% w/v) and strong (60% w/v) sulfuric acid concentrations for extraction. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA) were used to characterize each waste resource and extracted cellulosic materials. Furthermore, nanocelluloses were studied by zeta potential, size analysis, and transmission electron microscopy (TEM). Cellulose nanowhiskers were successfully obtained and More >

    Microfibrillated Cellulose from Sugarcane Bagasse as a Biorefinery Product for Ethanol Production

    Rafael Grande1*, Eliane Trovatti2, Maria Tereza B. Pimenta3, Antonio J. F. Carvalho1

    Journal of Renewable Materials, Vol.6, No.2, pp. 195-202, 2018, DOI:10.7569/JRM.2018.634109

    Abstract Research involving the preparation of microfibrillated cellulose (MFC) from sugarcane bagasse is a relevant topic to the production of new nanomaterials and more accessible cellulose substrates for the production of second generation ethanol. Regarding the transformation of cellulose into glucose, the precursor of second generation ethanol, this nanosized cellulosic substrate represents a more appropriate material for the chemical hydrolysis process. The high aspect ratio of MFC improves hydrolysis, requiring mild conditions and decreasing the generation of by-products. Here, MFC was prepared from sugarcane bagasse by ultrasound defibrillation. This material was oxidized with 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) to More >

    Influence of Sugarcane Bagasse Fiber Size on Biodegradable Composites of Thermoplastic Starch

    Bruno Henrique dos Santos, Karen de Souza do Prado, Asaph Armando Jacinto, Márcia Aparecida da Silva Spinacé*

    Journal of Renewable Materials, Vol.6, No.2, pp. 176-182, 2018, DOI:10.7569/JRM.2018.634101

    Abstract Although thermoplastic starch (TPS) is biodegradable, its low mechanical resistance limits its wide application. Sugarcane bagasse (SB) fibers can be used as reinforcement in TPS matrix composites, but the influence of fiber size on the properties of the composite is still unknown. In this study, TPS composites reinforced with SB short fibers of four sizes were processed and characterized in order to analyze the influence of fiber size on the mechanical properties of the TPS/SB composite. It was observed that the interaction between fiber and matrix was good and optimized when the fibers are sifted More >

    Kênia F. R. Lamounier1, Patrisia O. Rodrigues1, Daniel Pasquini2*, Milla A. Baffi1

    Journal of Renewable Materials, Vol.6, No.2, pp. 169-175, 2018, DOI:10.7569/JRM.2017.634151

    Abstract This study investigates the efficiency of a crude enzymatic extract produced by Aspergillus fumigatus SCBM6 by solid state fermentation (SSF) in the hydrolysis of alkali pretreated sugarcane bagasse (PTB). After SSF using in natura sugarcane bagasse (SCB), the enzymatic extract presented 21.33 U.g–1 of β-glucosidase and 544.46 U.g–1of xylanase. The alkaline pretreatment with sodium hydroxide (2% NaOH (w/v) removed 43% of the lignin from PTB and the cellulosic fraction increased to 75%. The hydrolysis was optimized as a function of time, temperature, and concentration of PTB. After hydrolysis, the maximum yield (30.05%) of total released More >

    Alternatives of Small-Scale Biorefineries for the Integrated Production of Xylitol from Sugarcane Bagasse

    Nicolás M. Clauser1*, Soledad Gutiérrez2, María C. Area1, Fernando E. Felissia1, María E. Vallejos1

    Journal of Renewable Materials, Vol.6, No.2, pp. 139-151, 2018, DOI:10.7569/JRM.2017.634145

    Abstract Small-scale biorefinery from sugarcane bagasse offers new possibilities to the sugar and ethanol industries. The aim of this study was to evaluate the feasibility of a small-scale biorefinery for the production of xylitol from sugarcane bagasse. The liquid fraction from the autohydrolysis treatment was selected as the source of sugars for xylitol and two scenarios were analyzed for the residual solid: ethanol or pellet production. A technical-economic analysis of alternatives was applied. The internal rate of return (IRR) was used to compare the selected proposals. The highest IRR values were obtained when processing 70,000 dry More >
