Jin Zhu, Professor, Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, China.
Prof. Jin Zhu got his Ph.D. from Marquette University in 2001 and did postdoctoral research at Cornell University from 2001 to 2003. He worked at several US companies before he returned China in 2009. He is currently working at Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences (NIMTE). His research interests are bio-based polymers. He has published more than 220 research papers and 100 patents granted. Several technologies have been transferred to companies and commercialized. He is also the chief book editor of bio-based polymer materials& bio-based furan polyesters which are both published by China Science Press.

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.

  • 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
