Summary: The study investigated the effect of compounding and plastic processing methods on the physical properties of starch-based bioplastics reinforced with sugarcane bagasse cellulose fibers. Twin-screw extruders and injection molding were found to result in a more homogeneous distribution of fibers and improved mechanical properties. The solubility of the bioplastics ranged from 24.9% to 28.2%, making them a viable alternative to conventional plastics.

Summary: This research paper explores the use of agricultural waste ash (AWA) as a partial substitute for cement to produce ultrahigh-strength concrete (UHSC), and investigates the impact of using sugarcane bagasse ash (SBA) and corn stalk ash (CSA) on UHSC properties. The findings show that replacing 24% of cement mass (SBA 20% + CSA 4%) can result in UHSC with compressive and flexural strengths exceeding 205 and 27 MPa, respectively, at 28 days. Higher replacements of AWA (SBA 30% + CSA 8%) lead to lower permeability.

Summary: The aim of this study was to evaluate the anaerobic degradability and potential recovery of biomethane from different bioplastics. The results showed that certain polylactic acid-based items can degrade completely and contribute positively to biomethane production. Starch-based items showed a faster degradation of the starch component compared to the polyester component. Anaerobic digestion and/or anaerobic digestion coupled to digestate composting may be the best strategy for disposing of these wastes while meeting the principles of Circular Economy.

Summary: Finding an environmentally acceptable solution to the increasing plastic demand and ecological destruction is crucial. This study focused on the environmentally friendly production of bioplastic samples derived from corn starch, rice starch, and tapioca starch. By testing the physical and chemical properties of the samples produced with different ratios of fillers and plasticizers, it was found that starch-based bioplastics are a better alternative material for the packaging sector.

Summary: The study focuses on using agricultural waste ash as a partial substitute for OPC to produce sustainable ultra-high-performance concrete (SUHPC). Different agricultural residue ashes (RHA, SLA, and OWA) were used to replace 50% of the OPC weight. The effects on the properties of UHPC were evaluated, including slump flow, compressive strength, tensile strength, flexural strength, water sorptivity, permeability, and chloride penetration. The results showed that SUHPC can be prepared with a compressive strength of more than 155 MPa when 50% of the OPC is replaced with (SLA 25% + RHA 25%).

Summary: The production of bioplastics, mainly from polysaccharides such as starch, has become a growing strategy to mitigate the environmental impacts of plastic waste. The use of plasticizers, blends, and reinforcement with lignocellulosic components has shown promising and environmentally safe alternatives for overcoming the limitations of bioplastics.

Summary: Ideal climatic and environmental conditions in Sri Lanka make it a perfect place for sugarcane cultivation all year round. However, this leads to the production of a significant amount of sugarcane bagasse ash (SCBA), which has no commercial use but poses potential environmental and health risks. Recent studies have focused on using SCBA as a pozzolanic material in structural applications and this study evaluates the microstructure and pozzolanic capacities of SCBA samples from three sugar manufacturing facilities in Sri Lanka. By comparing the attributes of the samples and investigating the impact of SCBA generation process parameters, the ideal source of SCBA for pozzolanic material has been identified, along with other potential areas of research on SCBA and its applications.

Summary: The demand for green biodegradable plastics as a replacement for synthetic ones is increasing due to the current environmental threats. This study investigates the properties of bioplastics made from yam and potato tuber peels, including their morphology, physical, mechanical, and thermal characteristics. These bioplastics offer a sustainable solution to the problem of plastic waste and have potential applications in edible food packaging. The research found that bioplastics produced using hydrochloric acid exhibited darker color and higher modulus of elasticity compared to those produced using acetic acid. Additionally, waste potato peel-based bioplastics showed better water absorption and thermal stability than yam-based ones. Among all the bioplastics produced, waste potato peel-based bioplastics produced using hydrochloric acid exhibited the best physical, mechanical, and thermal properties.

Summary: UV-B irradiation was found to be a milder modification method than chemical oxidation on corn and potato carbohydrates. Potato carbohydrates, especially amylose, were more susceptible to changes upon irradiation, whereas corn ones, particularly amylopectin, were more stable. Functional properties were not significantly influenced by UV-B treatment.

Summary: This study presents a simple and efficient method for preparing high-performance novel starch-based bioplastics with excellent mechanical properties, water resistance, thermal resistance, and biodegradability. The bioplastics can be reused, crushed, dissolved, and re-poured after use and achieve complete degradation within six weeks. These characteristics make them a good alternative to traditional petroleum-based plastics.

Summary: In this article, the authors present a comprehensive characterization of superparamagnetic iron oxide nanoparticles (SPION) modified with the HBS ligand, showing improved colloidal stability in nanofluids for advanced oil recovery. The chemical modification of the particles' surface by the HBS ligand was demonstrated, and the anionic groups on the surface of SPION-HBS nanoparticles improved their stability and interfacial properties in enhanced oil recovery (EOR) application. The SPION-HBS nanofluid exhibited higher oil production, attributed to the more efficient change in wettability due to the electrostatic interactions between the sulfonate groups and the porous surface of limestone rock.
