Abstract Straw utilization is a key issue related to agricultural production and air pollution control. In this study, a novel extrusion process was proposed to improve the physical and mechanical properties of the straw-reinforced linear low-density polyethylene (LLDPE) composite. Instead of crushing the straw and mixing it with plastic matrix, the new method mixes straw with plastic matrix in its original form. The intact long rice straws were parallelly spread on the LLDPE film and then rolled up together into a prefabricated roll. The rolls experienced three extrusion processes as follows: (1) twin-screw melting, cooling and crushing, single-screw extruding; (2) twin-screw…

Abstract The biodegradation of polymeric biocomposites formed from epoxidized linseed oil and various types of fillers
(pine needles, pine bark, grain mill waste, rapeseed cake) and a control sample without filler was studied during
180 days of exposure to two types of forest soil: deciduous and coniferous. The weight loss, morphological, and
structural changes of polymer composites were noticed after 180 days of the soil burial test. The greatest weight
loss of all tested samples was observed in coniferous forest soil (41.8%–63.2%), while in deciduous forest soil, it
ranged between 37.7% and 42.3%. The most significant changes in the intensities of…

Bio-based/Degradable Materials towards A Sustainable Future)
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…

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…

Abstract With a growing population, changes in consumerism behavior and trends in consumption in Indo-Pacific Asia, our seafood processing and consumption practices produce a large volume of waste products. There are several advantages in regulating and sustaining shellfish processing industries. The major advantage of waste management is that it leads to better conservation of natural resources in the long run. Shrimp shell waste contains useful biomaterials, which are still untapped due to inadequate waste disposal and solid waste management. Chitin, the major component of shell waste, can be extracted either chemically or biologically. The chemical extraction approaches, which use acids and…

Abstract The construction of grouting butt joints of bamboo tubes is simple and efficient. However, when the joint is bent, the low tensile strength of the mortar easily leads to cracking of the mortar prior to the failure of the bamboo tube. In this paper, a comparative test of the bending capacity was performed on grouting butt joints reinforced by nonperforated, fully perforated, and semiperforated steel plates embedded in bamboo tubes to obtain the load-displacement curves and ultimate bearing capacity of various specimens. The strengthening effect of CFRP pasted on bamboo tubes was also studied. The results show that the opening…

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)…

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…
