This study evaluates the economic cost and sustainability of treating residual municipal solid waste (MSW) through five management scenarios. In baseline scenario (Bsc), all was managed landfilling, while in 1 (Sc1) treated by incineration. Sc2 employed anaerobic digestion (AD) for food Sc3 AD waste, incineration combustible plastic wastes, landfilling. Sc4 using AD, incineration, recycling was...

Nutrient depletion in Tanzanian sisal production has led to yield decreases over time. We use nutrient mass balances embedded within a life cycle assessment quantify the extent of for different systems, and then used circular economy principles identify potential cosubstrates from anaerobically digest with wastes. The biogas produced was generate bioelectricity digestate residual can be as fert...

background: dental waste can be hazardous to humans and the environment. objective: to determine the current status of dental waste management in private and public dental clinics and private dental offices in shiraz, southern iran. methods: this cross-sectional study was conducted at the shiraz university of medical sciences from february through june 2013. a stratified random sampling method ...

Among the many force s to which hydraulic structures are exposed to, the forces induced by cavitation incident are of typical hydrodynamic unknown forces. The aim of this study is to define these forces as coupled fluid-structure interaction under two dynamic effects. The first dynamic effect which incorporates facilities for dealing with cavitation fluid is based on the appearance and bursting...

This paper deals with water resource management problems faced from an Automatic Control point of view. The motivation for the study is the need for an automated management policy for an artificial reservoir (dam). Two problems are addressed in the article: the control of the dam gate, that is a typical control problem, and the definition of the water flow to supply to the user, that is a decis...

The waste from semiconductor manufacturing processes causes serious pollution to the environment. In this work, a non-toxic material was developed under room temperature conditions for the fabrication of green electronics. Flexible organic thin-film transistors (OTFTs) on plastic substrates are increasingly in demand due to their high visible transmission and small size for use as displays and ...

Abstract Plastic is a product widely used daily and contributes to huge waste, which can cause potential environmental impact worldwide. The production of bioplastics lessen plastic waste while also benefiting the environment. There are still few studies examining influence in different contexts. This investigation assesses cradle-to-gate life cycle durian peel-derived considering their contrib...
