In the rapidly developing modern society, many raw materials, such as crushed limestone and river sand, which are limited, are consumed by the concrete industry. Naturally, the usage of waste materials in concrete have become an interesting research area in recent years, which is used to reduce the negative influence of concrete on the environment. Hence, this paper presents the development of ...

Microplastics are widespread in coastal and marine environments, sediments serve as a sink for microplastics. In this study, four sediment cores were collected from the Kuala Gula Mangrove area. The abundance of microplastics mangrove ranged 25–130 items/kg dry weight. highest microplastic was observed at KG04 site near mouth river. number by sampling significantly different (p < 0.01), with...

Bio-based materials and new dyeing technologies have gained growing interest, as companies actively want to enhance their products sustainability remove environmental hazardous pollutants. This article describes for the first time waterless studies using supercritical carbon dioxide (SC-CO2) a natural anthraquinone dye emodin polylactide (PLA) polyester (PET) fabric colouration. The colour of d...

Polypropylene (PP) hybrid composites were prepared by the combination of natural reinforcements and poly(ethylene terephthalate) (PET) fibers. Wood, flax, sugar palm fibers used to increase stiffness strength, while PET served improve impact resistance. Interfacial adhesion was increased using a maleated PP (MAPP) coupling agent. The containing 20 wt% homogenized in twin-screw compounder then i...
