US transportation agencies have been increasingly using recycled asphalt shingles (RAS) in hot mix asphalt (HMA) applications over the last 25 years. Initial use of RAS started with recycled postmanufacturers shingles, but now agencies are showing a growing interest in using post-consumer (tear-off) RAS in asphalt applications. Post-consumer asphalt shingles typically have 20 to 30 percent asph...

Inertness and the indiscriminate use of synthetic polymers leading to increased land and water pollution are of great concern. Plastic is the most useful synthetic polymer, employed in wide range of applications viz. the packaging industries, agriculture, household practices, etc. Unpredicted use of synthetic polymers is leading towards the accumulation of increased solid waste in the natural e...

Polyhydroxyalkanoates (PHA) are efficient, renewable and environment friendly polymeric esters. These polymers are synthesized by a variety of microbes under stress conditions. This study was carried out to check the suitability of waste frying oil in comparison to other oils for economical bioplastic production. Six bacterial strains were isolated and identified as Bacillus cereus (KF270349), ...

Finding new uses for waste or discarded material is an important environmental goal; being able to use a waste material to treat another waste is an even more attractive objective, and this was the purpose of the present work. We previously showed that used automobile tires have an affinity for a toxic contaminant, dichlorophenol (DCP), absorbing and releasing it based on concentration driving ...

• The investigated hospital uses 531g of plastic consumables/patient/day. most important consumables are PPE, accounting for 52% the polymers. relevant polymers PP and latex. Plastic packaging accounts an additional 3% weight consumables. studied account 20% hospital's mixed waste. Plastics have become omnipresent in healthcare but quantitative data on mass flows scarce. This study, therefore, ...

Owing to the overconsumption of petroleum-based resources and growing demand for fossil-based fuels chemicals, it has become imperative adopt alternative that are renewable. With availability biomass, is believed this technology capability valorize waste into wealth. Recently, efficient utilization plant a chief renewable resource, gained tremendous attention in research as offers distinct soci...

Polymeric materials have become an integral part of our society, and their high demand has created a large quantity polymers that end up in the waste stream.

Transcriptomes and proteomes of Pseudomonas putida LS46 cultured with biodiesel-derived waste glycerol or waste free fatty acids, as sole carbon sources, were compared under conditions that were either permissive or non-permissive for synthesis of medium chain length polyhydroxyalkanoates (mcl-PHA). The objectives of this study were to elucidate mechanisms that influence activation of biopolyme...
