Microwave (MW)-assisted torrefaction and pelleting could enhance biomass fuel properties energy applications. Plastic wastes are considered as a replacement source binder in pellets to minimize their effect on the environment pollutants. High-density polyethylene (HDPE), an extractable plastic from recycling waste, was investigated for torrefied wheat barley straw pellets. Fuel pellet character...

Information on the flows of specific polymers through anthroposphere forms basis any assessment environmental implications plastic. This work presents a dynamic probabilistic material flow analysis seven commodity thermoplastics: low-density polyethylene (LDPE), high-density (HDPE), polypropylene (PP), polystyrene (PS), expanded (EPS), polyvinylchloride (PVC), and terephthalate (PET). The exami...

Nowadays, waste has become a problem faced by people worldwide, especially in Indonesia. Wastes that are difficult to process, like plastics, can disturb environmental aesthetics, cleanliness, and health. They have power is decipher, so the researcher applied several methods them. Through an experimental this research designed products of lighting elements for cafés made plastic bottles types P...

the polymeric and non-polymeric petrochemical wastes are environmentally unfavorable materials. we have to found a way to reuse these wastes in a safe manner. in styrene-butadiene rubber (sbr) production plant two major wastes are produced one is a fine rubber powder and the other is recycled n-methyl pyrrolidone (nmp). in high-density polyethylene (hdpe) production plant also a low molecular w...

The purpose of this study was to investigate the validity of infrared tympanic temperature (IR T(ty)) as a thermal index to evaluate the heat strain of workers in hot environments, in comparison with rectal temperatures at various depths (T(re-4, -8, and -16) for 4, 8 and 16 cm from the anal sphincter). Eight males underwent twelve experimental conditions: two activities (rest and exercise) × t...

The experiment was conducted in three model drinking water distribution systems (DWDSs) made of unplasticized polyvinyl chloride (PVC), silane cross-linked polyethylene (PEX) and high density polyethylene (HDPE) pipes to which tap water was introduced. After 2 years of system operation, microbial communities in the DWDSs were characterized with scanning electron microscopy, heterotrophic plate ...

Soil fumigants are used to control a wide variety of soil-borne pests in high-cash-value crops. Application of soil fumigants through drip irrigation systems is receiving increasing attention as a method to improve the uniformity of fumigant application. Little information is available on the emissions and soil distribution of fumigants following subsurface drip application, or the effect of pl...

Selective laser sintering (SLS) has been investigated for the production of bioactive implants and tissue scaffolds using composites of high-density polyethylene (HDPE) reinforced with hydroxyapatite (HA) with the aim of achieving the rapid manufacturing of customized implants. Single-layer and multilayer block specimens made of HA-HDPE composites with 30 and 40 vol % HA were sintered successfu...

Banana fiber (BaF)-filled composites based on high density polyethylene (HDPE)/Nylon-6 blends were prepared via a two-step extrusion method. Maleic anhydride grafted styrene/ethylene-butylene/styrene triblock polymer (SEBS-g-MA) and maleic anhydride grafted polyethylene (PE-g-MA) were used to enhance impact performance and interfacial bonding between BaF and the resins. Mechanical, crystallizat...
