Summary

Bio-based and biodegradable materials have special characteristics such as green, environmental protection, renewable, easy degradation and so on, they mean great significance to realize the goal of carbon neutrality. more and more enterprises and institutions have made great investment in this area, the global key technology also face constant breakthrough, product variety and market expanding, it shows a strong momentum of development. In the next 10 years, at least 20% of petrochemical products, about $800 billion of petrochemical products can be replaced by Bio-based and biodegradable products, however the current replacement rate is less than 5%, every one should make more efforts for its development.

 

The overall goal of this special issue is Bio-based and biodegradable materials, Topics of interest include but not limited as below:

 

1 Preparation of bio-based chemicals, bio-chemical technology, bio-fermentation technology, biomass catalysis;

2 New products, new processes and new equipment of bio-based auxiliaries, bio-based polymer materials and bio-based fibers;

3 New products, new processes and new equipment of biodegradable materials;

 

New knowledge reported in this special issue will provide guidance for sustainable development as well as future manufacturing of bio-based and degradable products.

  • Study on the Properties of Esterified Corn Starch/Polylactide Biodegradable Blends
  • Abstract Fully bio-based and biodegradable starch/polylactic acid blends have received increasing attentions for their biodegradability and potential to offset the use of unsustainable fossil resources, specifically, their application in packaging. Herein, corn starch was first esterified with maleic anhydride and then compounded with polylactide (PLA) to prepare esterified corn starch/polylactic acid blends with starch content up to 35 wt%. The structures, morphologies, thermal and mechanical properties of starch or blends were investigated. The results showed that corn starch was successfully grafted with maleic anhydride, which showed increased crystallinity and particle size than native starch. Esterified corn starch/polylactic acid blends showed good… More

  • The Fabrication of Water-Soluble Chitosan Capsule Shell Modified by Alginate and Gembili Starch (Dioscorea esculenta L)
  • Abstract Capsule shells have been successfully fabricated from water-soluble chitosan (WSC) with the addition of alginate and Gembili starch. WSC was synthesized from crab shell chitosan by depolymerization reaction. The capsule shells were made with the composition of WSC: Alginate, 2:1, 3:1 and 4:1 (w/w) with and without the addition of Gembili starch. Gembili starch was added with a ratio of Alginate: Starch, 1:1 (w/w). The capsule shell properties were evaluated according to Indonesian Pharmacopoeia standard. The solubility test showed that the capsule shells were comply with the standard. The highest degrees of swelling in water and HCl 0.1 N solution… More

  • Preparation of Hollow-Porous Rosin-Based Polyurethane Microspheres with pH-Responsive Characteristics
  • Abstract Preparation of polymer microspheres from naturally occurring resource is a challenge. Here, a rosin-based polyol (RAG) was used to prepare polyurethane resin (RPU) firstly, and then act as both self-assembled precursor and emulsifier, rosin based polyurethane microspheres (RPUMs) were prepared. In the process of self-emulsification, the RPU formed vesicles by self-assembly. The outer shell of the vesicle consisted of hydrophilic segments, while the inner shell contained the hydrophobic phase. After cross-linking the RPU and removal of the solvent in the core, the porous-hollow microspheres with pH-sensitive were obtained. The microspheres were characterized by optical microscope (OM), scanning electron microscopy (SEM)… More

  • Chemically Modified Lignin: Correlation between Structure and Biodegradability
  • Abstract Lignin is the most abundant heteropolymer based on aromatic subunits in nature. Large quantities of lignin are annually produced from pulping processes and biorefinery industries. Its unclearly defined structure and difficult biodegradation mainly limit its utilization. This work focused on the effect of hydroxylation of lignin on its microbial degradation. Butyloxy carbonyl-modified lignin, and hydroxylated-lignin were synthesized with di-tert-butyl dicarbonate and hydrogen peroxide, respectively, using lignin as raw material. The degradation of the modifiedlignins both by P. chrysosporium and B. subtilis were analyzed using UV-vis spectroscopy. Results revealed that the lignin degradation velocity raises with the increase hydroxylation level of… More
