BACKGROUND High Density Polyethylene (HDPE) is one of the most often used polymers in biomedical applications. The limitations of HDPE are its visco-elastic behavior, low modulus and poor bioactivity. To improve HDPE properties, HA nanoparticles can be added to form polymer composite that can be used as alternatives to metals for bone substitutes and orthopaedic implant applications. METHOD I...

Automated solid waste processing is a very compli­ cated task: complicated equipment should be consid­ ered despite the fact that it can cause inordinate downtime if misapplied. Examples from laboratory re­ search and development are compared with reports of �eld experience to produce guidelines for distinguish­ mg between the types of equipment complexity that are and are not acceptable. A ren...

Although recycling is considered the core of a circular economy for returning materials to the supply chain, its procedures are poorly understood. Waste recycling is considered a big source of energy saving and a promoter of CO2 recovery. Besides that, it generates jobs and changes markets worldwide. The Brasilian National Policy on Solid Waste (PNRS) recognizes Waste Pickers as the major socia...

BACKGROUND The replacement of hard tissues demands biocompatible and sometimes bioactive materials with properties similar to those of bone. Nano-composites made of biocompatible polymers and bioactive inorganic nano particles such as HDPE/HA have attracted attention as permanent bone substitutes due to their excellent mechanical properties and biocompatibility. METHOD The HDPE/HA nano-compos...

Abstrak Perkerasan jalan terutama pada perkerasan lentur sering mengalami kerusakan yang lebih cepat akibat beban muatan kendaraan. Penggunaan bahan tambah ( additive ) menjadi salah satu alternatif digunakan untuk mendapatkan kualitas lapis baik. Penelitian ini bertujuan nilai Kadar Aspal Optimum (KAO) dan kinerja VIM, VMA VFA campuran lapisan AC-WC dengan penambahan limbah plastik High Densit...

Abstract Implementing plastic waste in construction materials is a sustainable disposal method to overcome pollution. The current study aims optimize the integration of cement bricks regarding their thermomechanical properties order develop an eco-friendly building material. Polyethylene terephthalate (PET) and high-density polyethylene (HDPE) partially substituted with different ratios (0, 2.5...

The main objective of this study was to determine the mold resistance and mechanical properties of fungicide-treated wood and bamboo flour/high density polyethylene (HDPE) composites. Zinc borate (ZB), 4,5-dichloro2-octyl-isothiazolone (DCOIT), zinc pyrithione (ZPT), and carbendazim (MBC) were used as fungicides. Then, treated and untreated samples were exposed to mold fungi (Aspergillus niger,...

Non-isothermal crystallization of neat high density polyethylene (HDPE), wood flour (WF)/HDPE composite (WPC), virgin Kevlar fiber (KF) reinforced WPC (KFWPC), and grafted Kevlar fiber (GKF) reinforced WPC (GKFWPC) was investigated by means of differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD). Several theoretical models were applied to describe the process of nonis...

The overall goal of this study is to propose a new approach simplify the recycling process for producing high quality material from waste beverage bottles and other sources at lower cost by using mechanical chemical reactions inside injection molding machines in one-step process. water soft drink are made PET material, while caps mainly HDPE. blends HDPE incompatible. resulted has poor properti...

Fiber-reinforced polymer (FRP) is the most promising technique in present era to bring sustainability, reliability, and pseudo ductility concrete structures due its superior properties. Thermoplastic thermoset polymers are thrown-out synthetic waste that contributes environmental pollution for a long time. Knowing this issue an attempt was made use High-Density Polyethylene Fiber (HDPE) fillers...
