Second generation biorefining in Ecuador: Circular bioeconomy, zero waste technology, environment and sustainable development: The nexus
Lourdes M. Orejuela-Escobar, Andrea C. Landázuri, Barry Goodell
2021, 6(2): 83-107. doi: 10.1016/j.jobab.2021.01.004
Abstract:
The projection of world population growth with concurrent generation of large volumes of agro-industrial waste that negatively affect the environment is of great concern. Therefore, this review article describes the nexus between concepts of Circular...
Integrated lignocellulosic biorefinery: Gateway for production of second generation ethanol and value added products
Amisha Patel, Amita R. Shah
2021, 6(2): 108-128. doi: 10.1016/j.jobab.2021.02.001
Abstract:
An increasing demand for energy and depleting petroleum sources has elevated the need for producing alternative renewable resources. Owing to the prominence of lignocellulosic biomass as bio-renewable and the most abundant resource on Earth, this cri...

Bacterial cellulose/glycolic acid/glycerol composite membrane as a system to deliver glycolic acid for anti-aging treatment
Bricard Mbituyimana, Lin Mao, Sanming Hu, Muhammad Wajid Ullah, Kun Chen, Lina Fu, Weiwei Zhao, Zhijun Shi, Guang Yang
2021, 6(2): 129-141. doi: 10.1016/j.jobab.2021.02.003
Abstract:

Glycolic acid (GA), as an anti-aging skincare ingredient, plays a pivotal role in anti-aging treatment. However, its benefits could be overshadowed due to its side effects including skin burning and irritation when overused. Bacterial cellulose (BC) ...

Chitin derived nitrogen-doped porous carbons with ultrahigh specific surface area and tailored hierarchical porosity for high performance supercapacitors
Si Zheng, Jianwei Zhang, Hongbing Deng, Yumin Du, Xiaowen Shi
2021, 6(2): 142-151. doi: 10.1016/j.jobab.2021.02.002
Abstract:

In this study, we report the fabrication of nitrogen rich activated nanosized carbon with hierarchical micro/mesoporous and ultrahigh specific surface area by template-free and one-step carbonization-activation method, which greatly simplified the pr...

Dynamical mechanical properties of wood-high density polyethylene composites filled with recycled rubber
Feiyu Tian, Ling Chen, Xinwu Xu
2021, 6(2): 152-159. doi: 10.1016/j.jobab.2021.02.007
Abstract:

Application of out-of-service rubber from a variety of sources is of both environment-protecting and resource-saving importance. To that end, recycled tire rubber was utilized as a filler to fabricate wood-high density polyethylene (HDPE) composite w...

Experimental evaluation of rice husk ash for applications in geopolymer mortars
G. Ogwang, P.W. Olupot, H. Kasedde, E. Menya, H. Storz, Y. Kiros
2021, 6(2): 160-167. doi: 10.1016/j.jobab.2021.02.008
Abstract:

Rice husks obtained from upland and lowland rice varieties were characterized for composition and content of ash. Each of the rice husk varieties was fired at temperatures of 600, 800 and 900 ℃ for a soaking period of 3 h. The resultant rice husk ash...

Packaging and degradability properties of polyvinyl alcohol/gelatin nanocomposite films filled water hyacinth cellulose nanocrystals
Henry C. Oyeoka, Chinomso M. Ewulonu, Iheoma C. Nwuzor, Chizoba M. Obele, Joseph T. Nwabanne
2021, 6(2): 168-185. doi: 10.1016/j.jobab.2021.02.009
Abstract:

Cellulose nanocrystals isolated from water hyacinth fiber (WHF) have been studied as a reinforcement for polyvinyl alcohol (PVA)-gelatin nanocomposite. Central composite design was used to study and optimize effects of the PVA, gelatin and cellulose ...
