Special Issue Information

Dear Colleagues,

This Special Issue is designed to update the state-of-the-art technologies regarding bio-based composite products from biomass, such as wood, agriculture stem, and other natural fibers. We are welcoming any papers related to (but not limit to) the following subjects:

  1. Fiber retting: Technologies to convert biomass and agricultural bast into the fibers, including the mechanical retting, bacterial retting, chemical retting, and other techniques.
  2. Natural fiber characterizations: The physical and mechanical properties of different natural fibers including wood, kenaf, hemp, cotton, wheat straw, bamboo, sisal, flex, and others.
  3. Fiber treatments: (1) To enhance the interfacial bonding of the fibers and the performance of the resulting composites; (2) to functionalize the fibers for functional composite products.
  4. Bio-based resin, including, tannin, protein, soy, and other plant-based adhesives, used for the bio-based composites.
  5. Bioproducts manufacturing: Processing techniques for both structural and non-structural natural fiber composites.
  6. Physical and mechanical properties, including decay resistant, biodegradability, mechanical performance, and physical performance (thermal, sound, and others) of the natural fiber composites.
  7. Bioproducts applications for automobile, building, transportation, aerospace, and others.
  8. Biomass to carbon conversion processes, biocarbon activation, as well as their applications, including water filtration and bio-electrodes.
  9. The life cycle analysis (LCA) of bioproducts

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The processes of hemp bast fiber retting, forming, and drying offer the opportunity for value-added products such as natural fiber-reinforced composites. A new process for the retting of raw bast fibers through enzyme-triggered self-cultured bacterial retting was developed in the lab-scale setup. This study focused on comparing the energy consumption and environmental impacts of this bacterial retting process with the thermochemical retting process currently widely used to obtain lignocellulosic fibers for composites. The gate-to-gate life cycle assessment (LCA) models of the two retting processes were constructed to run a comparison analysis using the TRACI (the tool for the reduction and assessment of chemical and other environmental impacts) method for environmental impacts and the cumulative energy demand (CED) method for energy consumptions. This work has demonstrated the advantages of the bacterial retting method from an environmental standpoint. The result of our research shows about a 24% gate-to-gate reduction in CED for bacterial retting and 20–25% lower environmental impacts relating to global warming, smog formation, acidification, carcinogenics, non-carcinogenics, respiratory effects, ecotoxicity, and fossil fuel depletion when compared to that of thermochemical retting.
