The identification and classification of plastics plays an important role in waste management and recycling processes. Present electrical and optical sorting techniques lack the required resolution for accurate identification in a high throughput manner for a diverse set of plastics commonly found in municipal waste. In this work a multi-spectral infrared spectroscopic technique is employed to ...
Application of waste bulk moulded composite (BMC) as a filler for isotactic polypropylene composites
The aim of this study was to produce isotactic polypropylene based composites filled with waste thermosetting bulk moulded composite (BMC). The influence of BMC waste addition (5, 10, 20 wt%) on composites structure and properties was investigated. Moreover, additional studies of chemical treatment of the filler were prepared. Modification of BMC waste by calcium stearate (CaSt) powder allows t...
Natural fiber as a sound-absorbing biocompisite material is believed to not only reduce noise pollution but also absorb heat. There are many underutilized coconut husks, which so far the use of husks conventional. The focus this research find right solution in well composite engineering for technological purposes. method will pure experiments using controlled specimens mechanical Engineering la...
This work investigates the feasibility of using recycled high density polyethylene (rHDPE), recycled polypropylene (rPP) and old newsprint fiber (ONP) to manufacture fiber reinforced composites. The boards were made through air-forming and hot press. The effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...
Tau proteins and amyloid-β (Aβ) peptides are the current recognized cerebrospinal fluid (CSF) biomarkers used as an aid in the diagnosis of Alzheimer's disease (AD). However, there is no consensus on their clinical use due to non-qualified cut-off values, probably related to the observed high pre-analytical and analytical variability. Standardized pre-analytical protocols have therefore been pr...
The Indonesian archipelago, especially Bali, has extensive coastline and marine waters. However, it is undeniable that some of these waters contain much plastic waste. Nusa Dua are located in the Bali Province area with many complex activities, ranging from port water sports, tourism, restaurants, hotels, fishing others, so they have a high potential for waste pollution. Plastic floats ocean wi...
More than 1,000 boxes of sewage sludge are stockpiled at this base camp. It was composted during the beginning of a pilot study in 2004. Armies around the globe have always had to deal with the problem of solid waste. Today, a large percentage of solid waste is packaging materials (cardboard, paper, and plastic), in addition to waste food and sewage sludge. While much of the solid waste generat...
The distribution, abundance, and characteristics of neuston plastic in the North Pacific, Bering Sea, and Japan Sea were studied during the 4-year period 1985-88 at 203 neuston stations encompassing ca. 91,000 m2 of sampling. The highest total density of neuston plastic was 316,800 pieces/km2 at lat. 35"59'N, long. 152"OO'E in Transitional Water east of Japan. The highest total concentration of...
