Conversion of urban wastes to utilizable sugars is very important as a vital step towards reduction environmental pollution. Consequently, this work was aimed at obtaining cellulase from the gut Oryctes rhinoceros larvae raffia palms in Itokin, Lagos State, Nigeria evaluate its degradability potential on different plant leaves and selected plastic bottles. Cellulase partially purified by combin...

This work reports the thermo-catalytic conversion of medical plastic wastes to fuel oil using detergent grade Zeolite A as catalyst. The effect catalyst on pyrolysis is ascertained from kinetic data obtained thermogravimetric analysis assuming it be a first-order reaction. significant reduction in activation energy thermal degradation reaction found presence runs were performed at different tem...

The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...

Construction and Demolition (C&D) wastes contribute the highest percentage of wastes worldwide (75%). Furthermore, ceramic materials contribute the highest percentage of wastes within the C&D wastes (54%). The current option for disposal of ceramic wastes is landfill. This is due to unavailability of standards, avoidance of risk, lack of knowledge and experience in using ceramic wastes in const...

This paper reexamines policies and outcomes concerning the NY Bight Restoration Plan, and the NY-NJ Harbor Estuary Program (NYNJHEP) precipitated by washups of marine debris and medical wastes in the New York Bight some 25-years ago. Findings indicate progress has been made but further work is necessary. Extensive beach closures have not occurred since 1987-88, although localized closings occur...

The deleterious environmental impacts caused by plastic wastes have attracted worldwide concern. The biobased and biodegradable polyhydroxyalkanoate (PHA) appears to be one of the potential candidates to replace some conventional plastics. However, high production cost of PHAs has limited their market penetration. The major cost absorbing factors are the upstream fermentation processes and the ...

Municipal solid waste (MSW) management has emerged as an important human and environmental health issue. A large number of poor, downtrodden marginalized urban women are thriving on these recyclable wastes and are potentially exposed to a variety of occupational biohazards and safety risks. At present there are about millions of women in India who scavenge the city’s garbage bins and MSW dispos...

Recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. Since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. In the present study, we used a solution electrospinning technique to synthesize nano/micr...

With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...
