- Abstract:
- ... Green waste (GW), rich in cellulose and hemicellulose, is a valuable resource. Developing alternative sustainable technologies to utilize GW is attracting increasing attention. In this study, microwave hydrothermal carbonization (MHTC) process parameters including holding temperature, holding time, and liquid-to-solid ratio were optimized by a response surface design to tailor the properties of hy ...

- Abstract:
- ... 3D printing enables the complex or customized structures production in high speed and resolution. However, the lack of bio-based materials with user-defined biochemical and mechanical property is a significant barrier that limits the widespread adoption of 3D printing for products fabrication. Development of eco-friendly natural-derived biopolymers for 3D printing technologies and their promising ...

- Abstract:
- ... Bamboo features the fastest growing speed and abundant in the plant kingdom. However, it remains a huge challenge to prepare large flat surface boards by directly sawing or cutting due to the hollow cylindrical shape of bamboo culms. We herein have demonstrated the preparation of facile scalable fabrication of larger flattened bamboo board without cutting it into arcs bamboo strips by high-press s ...

The main objective of this study was to evaluate the Ea of ground bamboo using near infrared spectroscopy in real time. 80 bamboo samples with different diameters were selected using random sampling. Ea was determined using the Coats-Redfern method, and Ea of reaction order (n) at n = 1 an ...

- Abstract:
- ... In emerging bioeconomies, the compostable biopolymers polyhydroxyalkanoates (PHAs) are desirable products due to their similarity to petropolymers. While industrial PHA production has been growing rapidly, obtaining a cheap and sustainable carbon source is still a challenge. Among biobased feedstocks, lignocellulose is a cheap, abundant and potentially sustainable carbon source. However, because o ...

In this study, a reutilization of caustic lye during cold caustic extraction (i.e., CCE) process to produce high-purity dissolving pulp and high-concentrated hemicellulose solution was proposed. The results showed that the lye can be reused about 12 times for producing high-purity dissolving pulps. With the number of CCE stages of 12, the hemicellulose in the lye can be auto-concentrated to about ...

- Abstract:
- ... Autohydrolysis (AH) prior to the kraft process is one way to valorize hemicelluloses. The presented results show that AH also has a beneficial effect insofar as kraft cooking can be substituted by soda cooking, and higher brightness levels can be achieved under the same bleaching conditions. The lignin has more free phenolic groups after AH, which is attributable to depolymerization, and which cou ...

It was found that both stresses, drought and excess of rain induced a decrease of uronic acid in the matrix and an increase of the structuring pectins. Besides, a drought led to an increase of hemicellulose p ...
